title: [Evaluation of the contractile function of the right ventricle in patients with mitral-tricuspid valve defect].
abstract: A comparative analysis is presented of the Sonnenblick contractility index, end-diastolic and systolic pressure in the right ventricle, cardiac index in 76 patients with mitral-tricuspid disease and with a mitral disease alone. Higher figures of the contractility index of the right ventricle were obtained in patients with an organic tricuspid defect with a predominance of insufficiency, than in those with mitral insufficiency and relative tricuspid insufficiency. The contractility index of the right ventricle decreases along with an increasing stenosis of the right venous ostium. The study has demonstrated that the patients with mitral-tricuspid defects tend to display a less distinct inotropic reaction to Digoxin as compared with those having a mitral defect alone.
