Restrictive cardiomyopathy is defined as heart-muscle diseasethat results in impaired ventricular filling, with normal ordecreased diastolic volume of either or both ventricles. Systolicfunction usually remains normal, at least early in the disease,and wall thickness may be normal or increased, depending onthe underlying cause.1 The condition usually results from increasedstiffness of the myocardium that causes pressure within theventricle (or ventricles) to rise precipitously with only smallincreases in volume. Since the condition affects either or bothventricles, it may cause symptoms and signs of right or leftventricular failure. Often, right-sided findings predominate,with . . .
