The gold-standard diagnosis of myocarditis is based on endomyocardial biopsy (EMB). The Dallas criteria, developed in 1986, define myocarditis as an inflammatory infiltrate with or without myocyte necrosis. The Dallas Myocarditis Panel has set forth useful criteria and guidelines in an attempt to classify the morphologic diagnosis of myocarditis.

In the 1980s the so-called Dallas Classification System was developed to diagnose LM, providing histopathological criteria for its diagnosis in endomyocardial biopsies (EMB).

The Dallas criteria for biopsy-based diagnosis of myocarditis, established in 1987, consist of myocyte necrosis and inflammation. A positive biopsy, however, does not correlate with clinical symptoms for example, fulminant from chronic myocarditis The diagnosis of acute viral myocarditis should be based on a high index of suspi-cion, attention to historical clues, and a thorough physical exam.The standard histologic crite-ria for establishing the diagnosis (the Dallas criteria (20)) were established in an adult population. Chow and Hauck performed serial myocardial biopsies on post-mortem hearts of patients who had died of myocarditis.17,18 Even with 5 biopsy samples, only two-thirds of patients studied would have had the diagnosis of myocarditis using the Dallas criteria. Myocarditis is a rare, potentially deadly, and often underdiagnosed cause of heart failure that primarily affects children and young adults. Historically, the diagnosis of myocarditis was confirmed by analysis of endomyocardial biopsy specimens. The Dallas criteria, proposed in 1986 The diagnosis of acute viral myocarditis should be based on a high index of suspi-cion, attention to historical clues, and a thorough physical exam.The standard histologic crite-ria for establishing the diagnosis (the Dallas criteria (20)) were established in an adult population.

Medical. Myocarditis - Genetic Alliance. Biopsy - MedlinePlus Health Information. The standard for the histopathologic diagnosis of myocarditis has been the Dallas criteria. Recently, immunohistochemical studies that include the specification and quantification of interstitial inflammatory cells have been proposed as the diagnostic approach for myocarditis.

In 1984, the Myocarditis Panel met in Dallas to set forth criteria and guidelines to characterize the morphologic diagnosis of myocarditis.1 The panel was . In order to better standardize histological diagnosis, Dallas criteria have been developed (table 3), for first and subsequent biopsies.

The histologic diagnosis of myocarditis was clarified by the Dallas criteria (see the following section on clinical manifestations and diagnosis), but these unfortunately did not include immunohistochemical findings demonstrating a T cellmediated immune response. Diagnosis and presentation of fatal myocarditis Kyt, Ville Saukko, Pekka Lignitz, Eberhard Schwesinger, Gnther Henn, VroniqueHistopathologic reanalysis showed that only 32 of the 142 subjects met the Dallas criteria for myocarditis (75 of pediatric and 28 of adult patients, P .001). Classic Dallas criteria for the pathologic diagnosis of myocarditis require the presence of inflammatory cells simultaneous with evidence of myocyte necrosis on the same microscopic section. Borderline myocarditis is characterized by inflammatory cell infiltrate without myocardial necrosis. The histologic Dallas criteria allow for two categories of myocarditis: active, in which myocyte damage is evident, and borderline, in which a cellular inflammatory infiltrate is not associated with myocyte injury or necrosis (Plate 48.1).2 However, the diagnosis of myocarditis is frequently presumed if a Myocarditis is a pathologic diagnosis made by endomyocardial biopsy, at the time of cardiac explantation, LVAD placement or at autopsy.(lymphocytic, eosinophilic, granulomatous) that is associated with myocyte necrosis or degeneration ( Dallas criteria).

Despite its considerable limitations, yielding diagnostic information in only 10 to 20 of cases,76 EMB findings remain the gold standard for unequiv-ocally establishing the diagnosis. Lake Louise consensus criteria is two out of the following three criteria to fulfil the diagnosis of myocarditis 5Endomyocardial biopsy is graded according to the Dallas criteria, with gradations of myocarditis, borderline myocarditis, and no myocarditis.

Acute myocarditis represents one of the most challenging diagnoses in cardiology, as currently noThe standard Dallas pathological criteria, which were published in 1986, served as the initial attempt to develop standardized diagnostic guidelines for the histopathological classification of myocarditis. The use of the Dallas criteria in the diagnosis of myocarditis is associated with poor sensitivity and specificity, mainly because of the sampling error related to the often focal distribution of the specific histological lesions in cardiac tissue and because of the variability in pathological interpretation Kenneth Lee Baughman, Diagnosis of Myocarditis: Death of Dallas Criteria (2006). never been seen unequivocally in the myocardium. except cytomegalovirus in immunocompromised hosts.

According to the Dallas criteria, acute myocarditis is defined by lymphocytic infiltrates in association with myocyte necrosis (Figs. 4A and 4B).
