title: Restrictive-type hemodynamics following valve surgery for rheumatic heart disease.
abstract: Over a six-year period three patients with rheumatic valvular disease presented with congestive heart failure due to abnormalities in myocardial diastolic function. Each patient previously had been operated for mitral stenosis; one patient had additional aortic valve replacement for aortic insufficiency. The mean time for the development of symptoms following surgery was 4.7 years. In all patients, left ventricular systolic function was normal (radionuclide or angiographic ejection fraction greater than 0.50). Abnormalities in diastolic function involved the left ventricle in all patients. Biopsy material from right (one patient) and left (one patient) ventricles was nonspecific in its histologic appearance. Other disease processes, such as constrictive pericarditis and diabetic cardiomyopathy were considered to be clinically unimportant in these patients. Restrictive-type hemodynamics in patients with postoperative rheumatic heart disease may comprise a newly recognized entity.
