[Studying the peculiarities of deformity of the left ventricular walls in patients with hypertrophic cardiomyopathy using vector-echocardiography].

Peculiarities of deformity of the left ventricle (LV) walls were studied in 93 patients in various variants of hypertrophic cardiomyopathy (HCMP). In accordance to complex echocardiography data, including vector-echocardiography, in HCMP the deformity grade and quantity of the affected segments of the LV myocardium have had depended directly on the stenosis degree of the LV tractus deferens (TD). Initially, a capacity for deformity lowers in basal segments of interventricular septum and in the LV anterior wall.

[Plasty of the left atrium in the isolated mitral valve prosthesis implantation].

Possibilities of the procedures conduction of the left atrium (LA) plasty in a mitral valve prosthesis (MVP) were studied. There were examined 553 patients, in whom surgical treatment in the clinic was conducted. In all the patients MVP was conducted for isolated mitral valve failure and dilatation of LA.

[Superior vena cava blood flow measurements for results prognosing of a bidirectional cava-pulmonary anastomosis in correction of hemodynamics parameters in patients with hypoplastic right ventricle].

The method of prediction the enability of closure atrial septal defect before operation or in pre-bypass period during the one and one-half ventricle repair of CHD with hypoplastic right ventricle was presented. The method is based on comparison of the initial blood flow on superior vena cava (SVC) and right-to-left shunt at atrial level. Defect can be closed if flow on SVC and shunt flow are approximately equal.

[Anatomical correction of the main vessels transposition. Echocardiographic estimation of cardiac parameters preoperatively and in immediate period after the operation].

Radical anatomic correction--operation of arterial switch--is performed in the main vessels transposition in majority of the world big cardiosurgical clinics, but its late results are studied insufficiently yet. Echocardiographic cardiac parameters preoperatively and in immediate postoperative period after anatomic correction in the main vessels transposition were presented. Comparative analysis of indexes, including estimation of anatomy and function of cardiac ventricles, depending on initial data and terms of the operation performance was conducted.
