64-487: The English name originates from the Ancient Greek prefix peri- (περί) 'around' and the suffix -cardion (κάρδιον) 'heart'. The pericardium is a tough fibroelastic sac which covers the heart from all sides except at the cardiac root (where the great vessels join the heart) and the bottom (where only the serous pericardium exists to cover the upper surface of the central tendon of diaphragm ). The fibrous pericardium

128-436: A pericardial window or pericardiostomy . The congenital absence of pericardium is rare. When it happens, it usually occurs on the left side. Those affected usually do not have any symptoms and they are usually discovered incidentally. About 30 to 50 percent of the affected people have other heart abnormalities such as atrial septal defect, patent ductus arteriosus, bicuspid aortic valve, and lung abnormalities. On chest X–ray,

192-537: A pitch accent . In Modern Greek, all vowels and consonants are short. Many vowels and diphthongs once pronounced distinctly are pronounced as /i/ ( iotacism ). Some of the stops and glides in diphthongs have become fricatives , and the pitch accent has changed to a stress accent . Many of the changes took place in the Koine Greek period. The writing system of Modern Greek, however, does not reflect all pronunciation changes. The examples below represent Attic Greek in

256-422: A bacterial infection, but may also occur following a myocardial infarction . Pericarditis is usually a short-lived condition that can be successfully treated with painkillers , anti-inflammatories , and colchicine . In some cases, pericarditis can become a long-term condition causing scarring of the pericardium which restricts the heart's movement, known as constrictive pericarditis . Constrictive pericarditis

320-404: A condition known as cardiac tamponade , causing pulsus paradoxus and potentially fatal circulatory failure . Fluid can be removed from the pericardial space for diagnosis or to relieve tamponade using a syringe in a procedure called pericardiocentesis . For cases of recurrent pericardial effusion, an operation to create a hole between the pericardial and pleural spaces can be performed, known as

384-472: A lack of contemporaneous evidence. Several theories exist about what Hellenic dialect groups may have existed between the divergence of early Greek-like speech from the common Proto-Indo-European language and the Classical period. They have the same general outline but differ in some of the detail. The only attested dialect from this period is Mycenaean Greek , but its relationship to the historical dialects and

448-419: A lesser degree. Pamphylian Greek , spoken in a small area on the southwestern coast of Anatolia and little preserved in inscriptions, may be either a fifth major dialect group, or it is Mycenaean Greek overlaid by Doric, with a non-Greek native influence. Regarding the speech of the ancient Macedonians diverse theories have been put forward, but the epigraphic activity and the archaeological discoveries in

512-631: A life-threatening complication, may present with dyspnea, low blood pressure , weakness, restlessness, hyperventilation (rapid breathing), discomfort with lying flat, dizziness, syncope or even loss of consciousness. This causes a type of shock, called obstructive shock, which can lead to organ damage. Non-cardiac symptoms may also present due to the enlarging pericardial effusion compressing nearby structures.  Some examples are nausea and abdominal fullness, dysphagia and hiccups, due to compression of stomach, esophagus, and phrenic nerve respectively. Any process that leads to injury or inflammation of

576-488: A normal pericardium is difficult to be seen on CT and MRI. A complete pericardial defect will show the heart displaced to the left with part of the lungs squeezed between inferior border of heart and diaphragm. Ancient Greek Ancient Greek ( Ἑλληνῐκή , Hellēnikḗ ; [hellɛːnikɛ́ː] ) includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC. It

640-543: A prefix /e-/, called the augment . This was probably originally a separate word, meaning something like "then", added because tenses in PIE had primarily aspectual meaning. The augment is added to the indicative of the aorist, imperfect, and pluperfect, but not to any of the other forms of the aorist (no other forms of the imperfect and pluperfect exist). The two kinds of augment in Greek are syllabic and quantitative. The syllabic augment

704-671: A separate historical stage, though its earliest form closely resembles Attic Greek , and its latest form approaches Medieval Greek , and Koine may be classified as Ancient Greek in a wider sense. There were several regional dialects of Ancient Greek; Attic Greek developed into Koine. Ancient Greek was a pluricentric language , divided into many dialects. The main dialect groups are Attic and Ionic , Aeolic , Arcadocypriot , and Doric , many of them with several subdivisions. Some dialects are found in standardized literary forms in literature , while others are attested only in inscriptions. There are also several historical forms. Homeric Greek

768-609: A standard subject of study in educational institutions of the Western world since the Renaissance . This article primarily contains information about the Epic and Classical periods of the language, which are the best-attested periods and considered most typical of Ancient Greek. From the Hellenistic period ( c.  300 BC ), Ancient Greek was followed by Koine Greek , which is regarded as

832-419: A two-part membrane surrounding the heart: the outer fibrous connective membrane and an inner two-layered serous membrane . The two layers of the serous membrane enclose the pericardial cavity (the potential space ) between them. This pericardial space contains a small amount of pericardial fluid , normally 15-50 mL in volume. The pericardium, specifically the pericardial fluid provides lubrication, maintains

896-510: A vowel or /n s r/ ; final stops were lost, as in γάλα "milk", compared with γάλακτος "of milk" (genitive). Ancient Greek of the classical period also differed in both the inventory and distribution of original PIE phonemes due to numerous sound changes, notably the following: The pronunciation of Ancient Greek was very different from that of Modern Greek . Ancient Greek had long and short vowels ; many diphthongs ; double and single consonants; voiced, voiceless, and aspirated stops ; and

960-556: Is a literary form of Archaic Greek (derived primarily from Ionic and Aeolic) used in the epic poems , the Iliad and the Odyssey , and in later poems by other authors. Homeric Greek had significant differences in grammar and pronunciation from Classical Attic and other Classical-era dialects. The origins, early form and development of the Hellenic language family are not well understood because of

1024-418: Is added to stems beginning with consonants, and simply prefixes e (stems beginning with r , however, add er ). The quantitative augment is added to stems beginning with vowels, and involves lengthening the vowel: Some verbs augment irregularly; the most common variation is e → ei . The irregularity can be explained diachronically by the loss of s between vowels, or that of the letter w , which affected

1088-644: Is called 'East Greek'. Arcadocypriot apparently descended more closely from the Mycenaean Greek of the Bronze Age. Boeotian Greek had come under a strong Northwest Greek influence, and can in some respects be considered a transitional dialect, as exemplified in the poems of the Boeotian poet Pindar who wrote in Doric with a small Aeolic admixture. Thessalian likewise had come under Northwest Greek influence, though to

1152-448: Is considered by some linguists to have been closely related to Greek . Among Indo-European branches with living descendants, Greek is often argued to have the closest genetic ties with Armenian (see also Graeco-Armenian ) and Indo-Iranian languages (see Graeco-Aryan ). Ancient Greek differs from Proto-Indo-European (PIE) and other Indo-European languages in certain ways. In phonotactics , ancient Greek words could end only in

1216-501: Is dullness to percussion, bronchial breath sounds and egophony over the inferior angle of the left scapula. This phenomenon is known as Ewart's sign and is due to compression of the left lung base. Patients with concern for cardiac tamponade may present with abnormal vitals and what's classically known as the Beck's triad , which consists of hypotension (low blood pressure), jugular venous distension and distant heart sounds. Though these are

1280-450: Is most often done by cutting through the pericardium and creating a pericardial window This window provides a path for the fluid to be drained directly into the chest cavity, which prevents future development of cardiac tamponade. In localized effusions, it might be difficult to get safe access for pericardiocentesis, hence a surgical procedure is preferred. In case of malignant effusions, the high likelihood of recurrence of fluid accumulation

1344-465: Is non-specific and may not help identify a pericardial effusion but a very large, chronic effusion can present as "water-bottle sign" on an x-ray, which occurs when the cardiopericardial silhouette is enlarged and assumes the shape of a flask or water bottle. Chest radiograph is also helpful in ruling out pneumothorax, pneumonia, and esophageal rupture. ECG: may present with sinus tachycardia , low voltage QRS as well as electrical alternans . Due to

1408-546: Is often roughly divided into the following periods: Mycenaean Greek ( c.  1400–1200 BC ), Dark Ages ( c.  1200–800 BC ), the Archaic or Epic period ( c.  800–500 BC ), and the Classical period ( c.  500–300 BC ). Ancient Greek was the language of Homer and of fifth-century Athenian historians, playwrights, and philosophers . It has contributed many words to English vocabulary and has been

1472-412: Is reserved for patients with poor echocardiogram findings and for assessing pericardial inflammation, especially for patients with continued inflammation despite treatment. CT and MRI imaging can also be used for continued follow up on patients. Pericardiocentesis : is a procedure in which fluid is aspirated from the pericardial cavity with a needle and catheter. This procedure can be used to analyze

1536-436: Is semi-rigid, while the serous pericardium is quite pliable. The same mesothelium that constitutes the serous pericardium also covers the heart as the epicardium , resulting in a continuous serous membrane invaginated onto itself as two opposing surfaces (over the fibrous pericardium and over the heart). This creates a pouch-like potential space around the heart enclosed between the two opposing serosal surfaces, known as

1600-455: Is sometimes treated by surgically removing the pericardium in a procedure called a pericardiectomy . Fluid can build up within the pericardial space, referred to as a pericardial effusion . Pericardial effusions often occur secondary to pericarditis , kidney failure , or tumours and frequently do not cause any symptoms. Large effusions or effusions that accumulate rapidly can compress the heart and restrict diastolic ventricular filling in

1664-411: Is suspected, echocardiography usually confirms the diagnosis and allows assessment of the size, location and signs of hemodynamic instability. A transthoracic echocardiogram (TTE) is usually sufficient to evaluate pericardial effusion and it may also help distinguish pericardial effusion from pleural effusion and MI. Most pericardial effusions appear as an anechoic area (black or without an echo) between

1728-471: Is the elasticity of the pericardium. When fluid fills the cavity rapidly, the pericardium cannot stretch rapidly, but in chronic effusions, the gradual fluid collection provides the pericardium enough time to accommodate and stretch with the increasing fluid levels. Patients with pericardial effusion may have unremarkable physical exams but often present with tachycardia , distant heart sounds and tachypnea . A physical finding specific to pericardial effusion

1792-532: Is urgently needed for evaluation when there is concern for hemodynamic compromise, a rapidly developing effusion or history of recent cardiac surgery/procedures. Cardiac CT and MRI scans: cross-sectional imaging with computed tomography (CT) can help localize and quantify the effusion, especially in a loculated effusion (an effusion contained to one area). CT imaging also helps assess for pericardial pathology (pericardial thickening, constrictive pericarditis, malignancy-associated pericarditis). Whereas cardiac MRI

1856-698: The Greek region of Macedonia during the last decades has brought to light documents, among which the first texts written in Macedonian , such as the Pella curse tablet , as Hatzopoulos and other scholars note. Based on the conclusions drawn by several studies and findings such as Pella curse tablet , Emilio Crespo and other scholars suggest that ancient Macedonian was a Northwest Doric dialect , which shares isoglosses with its neighboring Thessalian dialects spoken in northeastern Thessaly . Some have also suggested an Aeolic Greek classification. The Lesbian dialect

1920-459: The pericardial space or pericardial cavity , which is filled with a small amount of serous fluid to lubricate the heart's movements and cushions it from any external jerk or shock. The fibrous pericardium is the outside layer of the pericardium, made up of dense and loose connective tissue . While capable of some change in shape , it is largely non-pliable, which acts to protect the heart against blunt forces and sudden pressure change from

1984-501: The present , future , and imperfect are imperfective in aspect; the aorist , present perfect , pluperfect and future perfect are perfective in aspect. Most tenses display all four moods and three voices, although there is no future subjunctive or imperative. Also, there is no imperfect subjunctive, optative or imperative. The infinitives and participles correspond to the finite combinations of tense, aspect, and voice. The indicative of past tenses adds (conceptually, at least)

2048-1031: The 5th century BC. Ancient pronunciation cannot be reconstructed with certainty, but Greek from the period is well documented, and there is little disagreement among linguists as to the general nature of the sounds that the letters represent. /oː/ raised to [uː] , probably by the 4th century BC. Greek, like all of the older Indo-European languages , is highly inflected. It is highly archaic in its preservation of Proto-Indo-European forms. In ancient Greek, nouns (including proper nouns) have five cases ( nominative , genitive , dative , accusative , and vocative ), three genders ( masculine , feminine , and neuter ), and three numbers (singular, dual , and plural ). Verbs have four moods ( indicative , imperative , subjunctive , and optative ) and three voices (active, middle, and passive ), as well as three persons (first, second, and third) and various other forms. Verbs are conjugated through seven combinations of tenses and aspect (generally simply called "tenses"):

2112-490: The Archaic period of ancient Greek (see Homeric Greek for more details): Μῆνιν ἄειδε, θεά, Πηληϊάδεω Ἀχιλῆος οὐλομένην, ἣ μυρί' Ἀχαιοῖς ἄλγε' ἔθηκε, πολλὰς δ' ἰφθίμους ψυχὰς Ἄϊδι προΐαψεν ἡρώων, αὐτοὺς δὲ ἑλώρια τεῦχε κύνεσσιν οἰωνοῖσί τε πᾶσι· Διὸς δ' ἐτελείετο βουλή· ἐξ οὗ δὴ τὰ πρῶτα διαστήτην ἐρίσαντε Ἀτρεΐδης τε ἄναξ ἀνδρῶν καὶ δῖος Ἀχιλλεύς.

2240-665: The anatomic position of the heart in the chest ( levocardia ), and also serves as a barrier to protect the heart from infection and inflammation in adjacent tissues and organs. By definition, a pericardial effusion occurs when the volume of fluid in the cavity exceeds the normal limit. If large enough, it can compress the heart, causing cardiac tamponade and obstructive shock . Some of the presenting symptoms are shortness of breath , chest pressure/pain , and malaise . Important etiologies of pericardial effusions are inflammatory and infectious ( pericarditis ), neoplastic , traumatic, and metabolic causes. Echocardiogram , CT and MRI are

2304-550: The aorist. Following Homer 's practice, the augment is sometimes not made in poetry , especially epic poetry. The augment sometimes substitutes for reduplication; see below. Almost all forms of the perfect, pluperfect, and future perfect reduplicate the initial syllable of the verb stem. (A few irregular forms of perfect do not reduplicate, whereas a handful of irregular aorists reduplicate.) The three types of reduplication are: Irregular duplication can be understood diachronically. For example, lambanō (root lab ) has

2368-419: The augment when it was word-initial. In verbs with a preposition as a prefix, the augment is placed not at the start of the word, but between the preposition and the original verb. For example, προσ(-)βάλλω (I attack) goes to προσ έ βαλoν in the aorist. However compound verbs consisting of a prefix that is not a preposition retain the augment at the start of the word: αὐτο(-)μολῶ goes to ηὐ τομόλησα in

2432-400: The bedside and in a timely manner. A drainage tube is often left in place for 24 hours or more for assessment of re-accumulation of fluid and also for continued drainage. Patients with cardiac tamponade are also given IV fluids and/or vasopressors to increase systemic blood pressure and cardiac output. But in localized or malignant effusions, surgical drainage may be required instead. This

2496-438: The center of Greek scholarship, this division of people and language is quite similar to the results of modern archaeological-linguistic investigation. One standard formulation for the dialects is: West vs. non-West Greek is the strongest-marked and earliest division, with non-West in subsets of Ionic-Attic (or Attic-Ionic) and Aeolic vs. Arcadocypriot, or Aeolic and Arcado-Cypriot vs. Ionic-Attic. Often non-West

2560-457: The chambers (the capacity to expand/ conform to volume changes). During inspiration, right ventricle filling in increased, which causes the Interventricular septum to bulge into the left ventricle, hence leading to reduced left ventricular filling and consequently reduced stroke volume and low systolic blood pressure. Some patients with pericardial effusions may present with no symptoms and

2624-405: The classical findings; all three occur simultaneously in only a minority of patients. Patients presenting with cardiac tamponade may also be evaluated for pulsus paradoxus . Pulsus paradoxus is a phenomenon in which systolic blood pressure drops by 10 mmHg or more during inspiration. In cardiac tamponade, the pressure within the pericardium is significantly higher, hence decreasing the compliance of

2688-419: The diagnosis can be an incidental finding due to imaging of other illnesses. Patients who present with dyspnea or chest pain have a broad differential diagnosis and it may be necessary to rule out other causes like myocardial infarction , pulmonary embolism , pneumothorax , acute pericarditis, pneumonia, and esophageal rupture. Initial tests include electrocardiography (ECG) and chest x-ray. Chest x-ray:

2752-611: The dialect of Sparta ), and Northern Peloponnesus Doric (including Corinthian ). All the groups were represented by colonies beyond Greece proper as well, and these colonies generally developed local characteristics, often under the influence of settlers or neighbors speaking different Greek dialects. After the conquests of Alexander the Great in the late 4th century BC, a new international dialect known as Koine or Common Greek developed, largely based on Attic Greek , but with influence from other dialects. This dialect slowly replaced most of

2816-431: The effusion is compromising heart function and causing cardiac tamponade, it will need to be drained. Fluid can be drained via needle pericardiocentesis as discussed above or surgical procedures, such as a pericardial window . The intervention used depends on the cause of pericardial effusion and the clinical status of the patient. Pericardiocentesis is the choice of treatment in unstable patients: it can be performed at

2880-549: The fluid accumulation around the heart, the heart is further away from the chest leads, which leads to the low voltage QRS. Electrical alternans signifies the up-and-down change of the QRS amplitude with every beat due to the heart swinging in the fluid (as displayed in the ultrasound image in the introduction) . These three findings together should raise suspicion for impending hemodynamic instability associated with cardiac tamponade. Echocardiogram (ultrasound): when pericardial effusion

2944-748: The fluid but more importantly can also provide symptomatic relief, especially in patients with hemodynamic compromise. Pericardiocentesis is usually guided by an echocardiogram to determine the exact location of the effusion and the optimal location of puncture site to minimize risk of complications. After the procedure, the aspirated fluid is analyzed for gross appearance (color, consistency, bloody), cell count, and concentration of glucose, protein, and other cellular components (for example lactate dehydrogenase ). Fluid may be also sent for gram stain, acid fast stain, or culture if high suspicion of infectious cause. Bloody fluids may also be evaluated for malignant cells. Fluid analysis may result in: Treatment depends on

3008-408: The heart looks posteriorly rotated. Another feature is the sharp delineation of pulmonary artery and transverse aorta due to lung deposition between these two structures. If there is partial absence of pericardium, there will be bulge of the left atrial appendage. On CT and MRI scans, similar findings as chest X–ray can be shown. The left sided partial pericardium defect is difficult to see because even

3072-556: The historical Dorians . The invasion is known to have displaced population to the later Attic-Ionic regions, who regarded themselves as descendants of the population displaced by or contending with the Dorians. The Greeks of this period believed there were three major divisions of all Greek people – Dorians, Aeolians, and Ionians (including Athenians), each with their own defining and distinctive dialects. Allowing for their oversight of Arcadian, an obscure mountain dialect, and Cypriot, far from

3136-472: The historical circumstances of the times imply that the overall groups already existed in some form. Scholars assume that major Ancient Greek period dialect groups developed not later than 1120 BC, at the time of the Dorian invasions —and that their first appearances as precise alphabetic writing began in the 8th century BC. The invasion would not be "Dorian" unless the invaders had some cultural relationship to

3200-422: The leading causes are inflammatory, infectious, neoplastic and traumatic. These causes can be categorized into various classes, but an easy way to understand them is dividing them into inflammatory versus non-inflammatory. How much fluid is stored in the pericardial sac at one particular time is based on the balance between production and reabsorption. Studies have shown that much of the fluid that accumulates in

3264-612: The most common methods of diagnosis, although chest X-ray and EKG are also often performed. Pericardiocentesis may be diagnostic as well as therapeutic (form of treatment). Pericardial effusion presentation varies from person to person depending on the size, acuity and underlying cause of the effusion. Some people may be asymptomatic and the effusion may be an incidental finding on an examination. Others with larger effusions may present with chest pressure or pain, dyspnea , shortness of breath , and malaise (a general feeling of discomfort or illness). Yet others with cardiac tamponade,

3328-499: The older dialects, although the Doric dialect has survived in the Tsakonian language , which is spoken in the region of modern Sparta. Doric has also passed down its aorist terminations into most verbs of Demotic Greek . By about the 6th century AD, the Koine had slowly metamorphosed into Medieval Greek . Phrygian is an extinct Indo-European language of West and Central Anatolia , which

3392-484: The outside. It is continuous with the outer adventitial layer of the neighboring great blood vessels , fused with the central fibrous area of the diaphragm on its posterior aspect and attached to the posterior surface of the sternum by the sternopericardial ligaments. The serous pericardium , in turn, is divided into two parts: Both of these layers function in lubricating the heart to prevent friction during heart activity. The visceral serous pericardium extends to

3456-487: The perfect stem eilēpha (not * lelēpha ) because it was originally slambanō , with perfect seslēpha , becoming eilēpha through compensatory lengthening. Reduplication is also visible in the present tense stems of certain verbs. These stems add a syllable consisting of the root's initial consonant followed by i . A nasal stop appears after the reduplication in some verbs. The earliest extant examples of ancient Greek writing ( c.  1450 BC ) are in

3520-559: The pericardial cavity and the limited elasticity of the pericardium, fluid accumulation beyond the normal amount leads to an increased intrapericardial pressure which can negatively affect heart function. A pericardial effusion with enough pressure to adversely affect heart function is called cardiac tamponade . Pericardial effusions can cause cardiac tamponade in acute settings with fluid as little as 150mL. In chronic settings, however, fluid can accumulate anywhere up to 2L before an effusion causes cardiac tamponade. The reason behind this

3584-435: The pericardial sac is from plasma filtration of the epicardial capillaries and a small amount from the myocardium, while the fluid that is drained is mostly via the parietal lymphatic capillaries. Pericardial effusion usually results from a disturbed equilibrium between these two processes or from a structural abnormality that allows excess fluid to enter the pericardial cavity. Because of the limited amount of anatomic space in

3648-414: The pericardium is called pericarditis . This condition typically causes chest pain that spreads to the back and is made worse by lying flat. In patients suffering with pericarditis, a pericardial friction rub can often be heard when listening to the heart with a stethoscope. Pericarditis is often caused by a viral infection ( glandular fever , cytomegalovirus , or coxsackievirus ), or more rarely with

3712-399: The pericardium or inhibits appropriate lymphatic drainage of the fluid from the pericardial cavity leads to fluid accumulation. Pericardial effusions can be found in all populations worldwide but the predominant etiology has changed over time, varying depending on the age, location, and comorbidities of the population in question. Out of all the numerous causes of pericardial effusion, some of

3776-403: The root of the great vessels and joins the parietal serous pericardium at the anatomical base of the heart. This junction occurs at two areas: the ventricular outflow tracts where the aorta and pulmonary trunk leave the heart, and the inflow tracts where the superior / inferior vena cava and pulmonary veins enter the heart. The root of the great vessels and the associated reflections of

3840-435: The serous pericardium creates various smaller sacs and tunnels known as pericardial sinuses , as well as radiographically significant pericardial recesses , where pericardial fluid can pool and mimic mediastinal lymphadenopathy . The pericardium sets the heart in mediastinum and limits its motion, protects it from infection, lubricates it and prevents excessive dilation in cases of acute volume overload. Inflammation of

3904-517: The syllabic script Linear B . Beginning in the 8th century BC, however, the Greek alphabet became standard, albeit with some variation among dialects. Early texts are written in boustrophedon style, but left-to-right became standard during the classic period. Modern editions of ancient Greek texts are usually written with accents and breathing marks , interword spacing , modern punctuation , and sometimes mixed case , but these were all introduced later. The beginning of Homer 's Iliad exemplifies

3968-399: The underlying cause and the severity of the heart impairment. For example, pericardial effusion from autoimmune etiologies may benefit from anti-inflammatory medications. Pericardial effusion due to a viral infection usually resolves within a few weeks without any treatment. Small pericardial effusions without any symptoms don't require treatment and may be watched with serial ultrasounds. If

4032-423: The visceral and the parietal membrane. Complex or malignant effusions are more heterogeneous in appearance, meaning they may have variations in echo on ultrasound. TTE can also differentiate pericardial effusion based on the size. Although it's difficult to define size classifications because they vary with institutions, most commonly they are as follows: small <10, moderate 10–20, large >20. An echocardiogram

Most of the dialect sub-groups listed above had further subdivisions, generally equivalent to a city-state and its surrounding territory, or to an island.
