Acquired Left Ventricular Endocardial Constriction from Massive Mural Calcific Deposits

Le résumé fourni par la source

Impairment to left ventricular (LV) filling may result from left-sided cardiovascular conditions proximal to the left ventricle (mitral stenosis, cor triatriatum, pulmonary venous obstruction), 1 from LV myocardial conditions (including hypertrophic cardiomyopathy, 2 amyloidosis 3 and hemosiderosis 4 ), from pericardial constriction (of several causes), 5 and from LV endomyocardial fibrosis with or without eosinophilia. 6 The last condition, which occurs mainly in Africa, causes extensive LV endocardial fibrosis located primarily in the LV inflow tract and is associated with little or no mural endocardial calcific deposits. The common denominator of all of these conditions is a normal-sized or small LV cavity. This report describes a hitherto unreported cause of impairment to LV filling: massive LV endocardial calcific deposits associated with LV hypertrophy of undetermined origin.
