[Assessment of myocardial contractile function in the ventricles in acquired heart defects with planned surgical treatment].
The paper analyzes haemodynamic and myocardial parameters in 200 patients with rheumatic heart diseases (mitral and aortic) obtained during catheterization of cardiac cavities and angiocardiography. A relationship of certain haemodynamic parameters with contractility disorders in the left ventricle myocardium has been established. The analysis of all the myocardial and haemodynamic changes can characterize the degree of disorders in the contractility of the myocardium. Disorders in the contractility of the left ventricle myocardium were considered as marked, with the contractility index of the left ventricle myocardium less than 850 relative units, the end diastolic pressure of 15 mm Hg and over and the ejection phase below 55%. The determination of haemodynamic and myocardial parameters and clinical data are of great importance in the evaluation of indications and contra-indications for surgical treatment of patients with valvular defects of the heart.
