[X-ray study of the function of a "preserved" myocardium in chronic cardiac aneurysm compared to intracardiac hemodynamic data].

The data of X-ray, radiokymography and of intracardiac haemodynamic studies were compared in 45 cases of chronic cardiac aneurysms and varying degrees of circulatory insufficiency. Special attention was paid to the study of the functional state of the myocardium beyond the zone of the aneurysm that was conducted with the aid of radiokymography. A certain correlation was established between the amplitude of the radiokymographic curve along the left ventricular margin beyond the aneurysmal zone and the severity of the haemodynamic disorders.

[Clinical course, diagnosis and treatment of idiopathic hypertrophic subaortic stenosis].

Clinical, ECG and X-ray data as well as catheterizational and angiographic data on 20 patients with idiopathic hypertrophic subaortic stenosis were analysed. The problems of medical and surgical treatment of the disease were discussed. The indications for surgical treatment were defined on the basis of the authors' surgical experience (5 operated on patients) and literature data.
