title: [Function of the left cardiac ventricle in "pure" aortic insufficiency prior to and following valve replacement with a biological prosthesis].
abstract: Contractibility of the left ventricle was investigated in 15 patients with chronic aortic insufficiency with class II and III NYHA lesions. The patients were examined prior to and 6 months-2 years after valve replacement with biological prosthesis. The following parameters have been determined: end-systolic and end-diastolic left ventricular volumes, ejection fraction, mean rate of circular muscle fibers shortening, and segmental contractibility of the left ventricle. Valve replacement with biological prosthesis improved contract ability of the left ventricle in the great majority of the operated patients with chronic aortic insufficiency. Assessed parameters did not correlate well with those obtained following valve replacement.
