Cardiac tamponade and pericardial disorders in connective tissue diseases: case report and literature review.

摘要

Pericardial disorders occurring in connective tissue diseases are not uncommon and may present as acute or chronic pericarditis with or without an effusion. In many instances, a diagnosis of pericardial involvement is not found until autopsy. Echocardiography and other currently employed radiographic techniques have enhanced the ability to make a diagnosis. Approximate frequencies of common connective tissue disorders with pericardial involvement include scleroderma (59%), systemic lupus erythematosus (44%), mixed connective tissue disease (30%), rheumatoid arthritis (24%), and polymyositis/dermatomyositis (11%). Cardiac tamponade or constriction is rare. This article describes a patient with clinical features consistent with mixed connective tissue disease that presented with a pericardial effusion and cardiac tamponade. In addition, a review of pericardial involvement in connective tissue diseases and the occurrence of cardiac tamponade or constriction is included.
