title: [Intracardiac hemodynamics after pulmonary artery valvuloplasty].
abstract: Studies of intracardiac haemodynamics were conducted in 30 patients subjected to valvuloplasty of the pulmonary artery valve. The method of continuous (for several days) right ventricle and pulmonary artery catheterization was employed. The isometric hyperfunction of the right ventricle was found to persist following the elimination of pulmonary valve stenosis. Myocardial insufficiency then develops that requires intensive cardiac therapy.
