[Importance of radioisotope angiography in the diagnosis of vascular diseases].

Radioisotope angiography demonstrates successfully occlusion of the abdominal aorta, aneurysms of the thoracic and abdominal aorta, and occlusion of the iliac and femoral arteries. In occlusion of the renal artery this method supplements contrast vasography of the kidneys providing a quantitative concept of the functional peculiarities and dynamics of the renal blood flow. The results of radioisotope angiography were in full agreement with the clinical picture of the disease and the findings of contrast X-ray angiography in 81.7% of cases; in 11.3% they coincided partly and only in 7% of cases the results were dissimilar.

[Clinical value of the study of myocardial blood flow by the method of Xe133 clearance in ischemic heart disease].

The clearance of intracoronarily introduced 133Xe was employed in investigating the myocardial blood flow in 105 patients, 10 of whom--controls and 95 suffering from various manifestations of ischemic heart disease. Use was made of the biexponential calculation of the clearance curve by taking account of the fast (circulation in normal tissues) and slow exponent (circulation along the cicatricially-altered sections of the myocardium) contributions to the common "effective" myocardial blood flow. In patients with ischemic heart disease a reduction of the myocardial blood flow depending upon the severity of the clinical picture and the degree of the coronary arteries lesion was revealed. A direct correlational dependence between the initial state of the myocardial circulation at rest and the level of the physical efforts tolerance was educed. A conclusion is drawn that the determination of the myocardial circulation by the method of the 133Xe clearance following intracoronarily administration of the substance should be done by taking account of the slow and fast exponents of the clearance curve, these exponents reflecting the circulation in sections of the myocardium differing in their functional activity.

[Hemodynamics and the heart volumes of patients before and after mitral valve prosthesis].

The article deals with a complex study of parameters of the hemodynamics and volume of the cardiac cavities in comparison with a clinical state of patients suffering from mitral defect before and in different periods following prosthesis of the mitral valve. On the basis of the results obtained during examination of 54 patients there was revealed a complete conformity between their clinical state, data of the hemodynamics, the volume of the heart and left auricle. A reverse development of many signs characteristic of the defect was established. The absence of an absolute improvement of some clinical and hemodynamic indices in remote periods following the operation in a number of patients was connected with a marked increase of the cardiac volumes before the operation, an unsatisfactory contractile capacity of the myocardium, the remaining of cardiac fibrillation after the operation.
