[Changes in heart size after surgical correction of rheumatic defects complicated by cardiomegaly in reoperated patients].

Twenty-nine patients with a cardiac volume ranging from 1074 to 1596 ml/m2 and with varying left ventricular myocardial contractility abnormalities underwent surgical therapy for acquired valvular disease. The volume of the heart became normal in 16 patients with hypokinesia of one of the left ventricular walls. There was no positive changes in cardiac sizes in 12 patients with hypokinesia of one or two left ventricular walls. Only one patients with left ventricular lateral wall and apical hypokinesia had an enlarged cardiac volume following the surgery.

[Errors and hazards in the diagnosis of aneurysms of the thoracic aorta].

Altogether 70 patients with thoracic aortic aneurysms were investigated. Of them 23 (32.9%) were investigated with prior diagnostic errors. In 13 patients the diagnosis of thoracic aortic aneurysm was made during erroneously performed thoracotomies (12 patients) and laparotomies (one patients). Diagnostic errors leading to bad tactical mistakes, were caused by insufficient patients' examination and wrong interpretation of x-ray findings.

[Diagnosis of aortic valve calcinosis with a view to the surgical treatment of aortic valve disease].

Combined roentgenologic/echocardiographic diagnosis of aortic valve calcinosis was made in 135 patients operated on for a rheumatic aortic heart disease. Four degrees of aortic valve calcinosis were identified: 1) isolated fine points of calcinosis, as revealed by echolocation and specific treatment of the removed valves; 2) small-focal calcinosis as revealed roentgenologically in 79.2% of cases and by echolocation, in 93%; 3) large-focal, and 4) wide-spread calcinosis, the latter two being detectable both roentgenologically and echocardiographically in all cases. The 4-degree classification of aortic valvular lesions allows a detailed assessment of the nature of the affection that is important for the choice of surgical procedure.

[State of the left-cardiac cavities after mitral valve prosthesis].

The article discusses the results of dynamic X-ray examination of the left heart cavities in 86 patients who underwent mitral valve prosthetics for mitral valvular disease. The follow-up period was 42 months. The left-ventricular volume was measured by a special method. It was established that positive time course of the left heart cavities in patients with the sinus rhythm is encountered in 1-3 months after the operation, and by the end of the first year the left cavities are stabilized and often attain their normal size. In patients with cardiac fibrillation, the left heart cavities decrease in size less frequently and at later periods, and total normalization does not occur.

[Recurrent right-ventricular hypertrophy in patients with congenital isolated stenosis of the pulmonary artery and outlet tract of the right ventricle in the immediate and late periods after surgery].

The degree of hypertrophy of the right ventricle is proportionate to the size of the systolic pressure gradient between the right ventricle and pulmonary artery prior to operation. The involution of hypertrophy is dependent on the type of stenosis, age of the patient and the term of surgery.

[Effect of the respiratory phases on the right jugular vein pulsation curve and pulmonary hemodynamics in mitral valve stenosis].

In patients with mitral stenosis the main and early changes in the pulsation curve of the right jugular vein consist in an elevation of the y-collapse. The height of the y-collapse correlates with the degree of venous congestion in the lungs, i.e. a parallelism exists between the signs of venous congestion in the pulmonary and general circulation systems. The degree of venous congestion in the lungs of patients with mitral stenosis varies with the phases of respiration. An elevation of the v-collapse in mitral stenosis cases is observed at early stages of the disease, simultaneously with the disorders in venous circulation in the upper lobes. The mechanism of circulatory disorders in the veins of the general circulation system may be due to not only pulmonary hypertension and right ventricular insufficiency, but also to the changes in the intrathoracic pressure secondary to the changes in pulmonary parenchyma.

[Systolic shift of the right ventricle base in patients with defects of the tricuspid valve].

A study of cinocardioangiograms taken in 29 patients (11-with "pure" tricuspidal insufficiency, 11-with a combined tricuspidal defect and 7-without any disturbances of the intracardiac hemodynamics, all of whom being examined for affections of the lungs and mediastinum) brought evidence that during the systole there occurred an intensive shifting of the right ventricle base (0.5-3 cm, the normal figure being 0.3-0.5 cm). This shift is caused by an increased stroke volume of the right ventricle due to regurgitation and high pulmonary arterial hypertension.
