[Correlation of functional indices of the left ventricle with structural changes in the myocardium].

11 with dilatative cardiomyopathy, 9 with valvular disease and 3 with ischemic heart disease--a full intracardial examination including right ventricular endomyocardial biopsy was performed. The most severe disorders of the hemodynamic parameters were found in the group of patients with dilatative cardiomyopathy. The pressure in the pulmonary artery was the highest of all groups of patients.

[Left atrial myxoma descending deeply into the cavity of the left ventricle].

A female patient, aged 59 is reported with a myxoma of the left auricle, pedunculated deep in left cardiac ventricle. Myxoma was echocardiographically diagnosed and confirmed by left atriography. On the fourth day after the diagnosis of myxoma, with a high efficiency of all examinations and organizational measures the patients was successfully operated.

[Coronary radiography in patients with valvular cardiopathies and stenocardia].

Seventy patients with valvular cardiopathies were performed selective coronarography besides the routine hemodynamic examination during the period 1973-1983. Those 70 patients could be subdivided in the following way: 46 with aortic, 17 - with mitral-aortic and 7 with mitral valvular lesion. Their average age is 46,15 +/- 1,42.

[Cardiovascular changes in the Marfan syndrome].

Marfan's syndrome in its complete and incomplete forms takes very often a course with cardiac complications, predetermining the fate of such patients. The incomplete forms often present difficulties for the timely etiological elucidation of the cardiac changes leading to a retardation in the prescribing a rational regime to the patients and timeliness of the operation treatment. The authors' team own observations are reported on 10 patients with Marfan's syndrome, one with complete form and nine--incomplete forms, all of them with cardiac complications; two with mitral insufficiency, three with aortic insufficiency, four with aortic and mitral insufficiency and one with aortic, mitral and tricuspidal insufficiency; seven of the patients had aneurysm at the initial part of the aorta, manifested to various degrees and one--dysplasia of aorta.

[Clinical diagnostic problems in myxoma of the left atrium].

The difficulties in the diagnosis of left auricle myxoma are discussed, proceeding from seven patients, observed by the authors. In two of them the diagnosis was confirmed by EchoCG and intracardial investigation (left atriography), in three--it was realized by exploratory thoracotomy, and in one of them proceeded directly into operation with extracorporal circulation (ECC), the second was radically operated (with ECC) after one month and the third died during operation due to acute obturation of mitral ostium by an extremely big myxoma; the other two patients were also successfully operated, the diagnosis being preoperatively made. Two patients died of cardiac failure, their diagnosis made at necropsy.

[Significance of sinus rhythm for ventricular function].

The changes in hemodynamics in conditions of dosed loading prior to and post cardioversion were followed up in 21 patients with valvular defects or atherosclerotic myocardiosclerosis and absolute arrhythmia with auricular fibrillation. In conditions of auricular fibrillation all the patients showed data about a deteriorated ventricular function (increased arterial-venous difference--tachycardia), both at rest and at dosed loading. One week after the sinus rhythm restoration, a considerable improvement of ventricular function was observed, at rest and loading (normal arterial-venous difference, higner minute and beat volume), suggesting the favourable effect of the restored sinus activity.

[Our experience in using temporary and permanent electric stimulation in conduction disorders].

The results from the observation of 49 patients with complete and incomplete AV block are reported, 33 of them with attacks of MAC syndrome; asystolia 25, ventricular tachycardia and ventricular fibrillation--8. Temporary electric stimulation is carried out in 31 patients (21 with chronic complete AV block and 10 with incomplete and complete with recent cardiac infarction). In all patients with chronic AV block but one, implantation of a permanent artificial rhythm nuide was necessary.
