[Diastolic changes in isolated stenosis of the pulmonary artery after correction of valvular defect]

Intracardiac hemodynamics and myocardial function were studied in 20 patients surgically treated for a valve defect. All the patients developed isolated stenosis of the pulmonary artery. It is emphasized that an early postoperative period in relevant correction proceeds with diastolic impairments. Some factors affecting the degree of the diastolic filling of the right ventricle upon the defect correction are determined. Adequate therapy of the disorders in proposed.
