Disease relevance of Pericarditis, Constrictive

• Distinguishing constrictive pericarditis from restrictive cardiomyopathy, usually due to amyloidosis, is a relatively frequent and difficult diagnostic problem [1].
• The relationship between constrictive pericarditis, seen in this patient, and the other more common manifestations of amyloid heart disease, and the hemodynamic profiles of amyloid cardiomyopathy and constrictive pericarditis are reviewed [1].
• METHODS: Pulsed-wave Doppler recording of mitral and superior vena cava flow velocities in 20 patients with chronic obstructive pulmonary disease who had > or = 25% respiratory variation in mitral E-wave velocity were compared with those of 20 patients who had surgically proved constrictive pericarditis [2].
• Rheumatoid arthritis was moderate to severe in 84% of the patients with cardiac tamponade and in 74% of the patients with constrictive pericarditis [3].
• Histologic documentation of intestinal lymphangiectasia in the absence of congestive heart failure, retroperitoneal masses, or constrictive pericarditis marks this case as demonstrating a unique association of SLE with intestinal lymphangiectasia [4].

• Letter: Fulminating idiopathic hemochromatosis presenting as constrictive pericarditis [6].
• Although rare, constrictive pericarditis, a potentially life threatening complication, may occur in systemic lupus erythematosus presumably with an immunological basis [7].
• Rheumatoid constrictive pericarditis should be suspected in any patient with rheumatoid arthritis and unexplained signs of right heart failure [8].
• In addition, there was a positive correlation between high adenosine deaminase values and the development of constrictive pericarditis [9].

Chemical compound and disease context of Pericarditis, Constrictive

• In addition to its routine use in monitoring rejection in heart transplant recipients, endomyocardial biopsy is indicated in the evaluation of possible infiltrative cardiomyopathy, in differentiating restrictive cardiomyopathy from constrictive pericarditis, and in diagnosing and monitoring doxorubicin cardiotoxicity [10].
• Sagittal and coronal cross-sections were particularly well-suited to show the non-uniformity of the pericardial thickening.These results indicate that RNA and MRI are complementary non-invasive methods, and can provide the functional and anatomical information required for the diagnosis of constrictive pericarditis [11].
• A rare case of constrictive pericarditis in procainamide-induced lupus erythematosus syndrome is reported [12].
• These data lend experimental support to recent clinical observations that suggest a causal relation between pericardial irrigation with povidone-iodine and the later development of constrictive pericarditis [13].
• False-positive echocardiographic diagnosis of pericardial effusion. Result of tumor encasement of the heart simulating constrictive pericarditis [14].

Biological context of Pericarditis, Constrictive

• Interventricular septal motion during ventricular diastole was analyzed using M-mode echocardiography in 13 patients with constrictive pericarditis and 12 patients with restrictive cardiomyopathy [15].
• Systolic time intervals were studied in 9 patients with documented constrictive pericarditis before and 15 to 20 minutes after intravenous administration of peruvoside (a quick acting digitalis-like glycoside) to determine underlying myocardial dysfunction [16].
• Maximal rate of fall of left ventricular pressure in cardiomyopathy and constrictive pericarditis [17].

Anatomical context of Pericarditis, Constrictive

• This report describes, for the first time, a patient with constrictive pericarditis caused by direct, extensive infiltration of the pericardium by amyloid, with only minimal amyloid in the myocardium, and a normal heart weight of 320 g [1].
• Indirect findings of impaired right ventricular diastolic filling (eg, dilatation of the inferior vena cava and right atrium) were identified in constrictive pericarditis and restrictive cardiomyopathy [18].
• RESULTS: There was more collagen in the myocardium of patients with constrictive pericarditis than in controls when measured either biochemically by hydroxyproline content (89.4 v 50.4 mg/g dry weight) or by histological measurement of the collagen fraction of the myocardium (2.4% v 7.0%) [19].
• In comparison to constrictive pericarditis, sympathetic efferent pathway is preserved in restrictive cardiomyopathy (p < 0.0001) [20].
• Of the latter, causes of ascites had already been identified in 13 (72.2%), including chronic renal failure in 7, systemic lupus erythematosus in 2, constrictive pericarditis in 2, chronic pancreatitis with chylous ascites in 1, and retroperitoneal lymph node metastasis with chylous ascites in 1 [21].

• Differentiation of constrictive pericarditis and restrictive cardiomyopathy using digitized echocardiography [28].
• We studied 30 patients referred for further evaluation of diastolic function who had a diagnosis of constrictive pericarditis or restrictive cardiomyopathy established by diagnostic tests, including clinical assessment, magnetic resonance imaging, cardiac catheterization, endomyocardial biopsy, and surgical findings [29].
• We describe two cases of severe constrictive pericarditis arising after allogeneic BMT conditioning involving total body irradiation and melphalan to treat Philadelphia-chromosome positive ALL [30].
