[The surgical procedure in an anomalous muscular bundle of the right ventricle combined with an interventricular heart septal defect].

A defect of the interventricular septum (DIVS) in the perimembranous zone can be a source of reversible (hypertrophy) and irreversible (fibrous degeneration) alterations of the moderator band (MB), normally or abnormally located in the right ventricle of the heart. DIVS goes with changes of MB in 7,27% of the cases. Operations are necessary in combinations of DIVS with changes of MB. Surgical correction is indicated to patients with DIVS and the abnormal muscular band. Operative treatment should not be used for the compensatorily hypertrophic MB, located normally or abnormally.

[Aortic valve prosthesis and the plication of a dissecting aneurysm of the ascending aorta in a patient with infectious endocarditis against a background of chronic kidney failure and its management by regular hemodialysis].

Some literature data are presented on the problem of cardiac surgery in patients with chronic renal insufficiency under regular hemodialysis and on the specificity of performing operations on such patients under conditions of artificial circulation. The authors describe their first experience of a one-step prosthezing of the aortal valve and plication of the dissecting aneurysm of the ascending part of the aorta in the patient receiving the regular hemodialysis during 5 years as well as the positive results of this original operation in dynamics of the first year of observations.

[A new surgical approach to the membranous heart septum and a method for eliminating its defect by a closed procedure].

On the basis of an analysis of the operative wound parameters carried out in significant autopsy material it is concluded that longitudinal median sternotomy and anterolateral thoracotomy in the third intercostal right space permit reaching the upper edge of the membranous septum of the heart using the new para-aortal access. This access allows to place a suture around the septum without opening the heart cavities by the closed method which is an alternative to the open correction of the interventricular septum defect in this ares. In clinical conditions the defect of interventricular septum was completely sutured in 3 patients, partially--in 2 patients, was not sutured in 1. In one patient only on of two interventricular septum defects was closed.

[Aneurysm of the membranous heart septum].

Cardiac membranous septal aneurysm is a rare congenital abnormality which occurs in 0.3% of patients as suspected congenital heart disease and in 19.1% as suspected ventricular septal defect. The main method for its diagnosis is biplane cineangiocardiography along with ventricular contrast injection. The patients with membranous septal aneurysm without hemodynamic abnormalities, complications, and concomitance with other congenital heart diseases require outpatient cardiologist's observation. Hemodynamic abnormalities, complications, and concurrent heart diseases are indications for surgery.

[Surgical topography of the membranous part of the interventricular heart septum].

An investigation of the membranous part of the interventricular septum of the heart during operations and an autopsy material has shown the shape and size of this structure of the heart to be variable and to have complex interrelations with many components of the heart. The ventricular portion of this part of the septum is always covered in some extent with chordae, threads of the tricuspid valve and its anterioseptal commissure. The atriotomic access may be an alternative to the surgical access via the right ventricle, but in this case it is necessary to dissect or cut off the septal cusp from the valve.

[Determination of the input and output volume of the right ventricle based on cineangiocardiography data].

The authors have developed a method of separate determination of the volumes of the input and output portions of the right ventricle by findings of cineangiocardiography made in two projections. The volume of the input portion had been shown to be 1,23 times as great as that of the output portion. A comparison of measurements of the volumes of the input and output portions and the total right ventricle as a whole will reveal their participation in the compensation of congenital and acquired heart diseases.

[Diagnosis and treatment of myxomas of the left atrium].

Two patients with myxomas of the left atrium stimulating mitral stenosis are described. The observations are analyzed. Recommendations for the diagnosis of left atrium myxomas by the methods of cineangiocardiography and echocardiography are given. The methods of operative treatment include ablation of the tumor under conditions of the artificial blood circulation with dissection of the tumor base within the limits of health tissues.
