[Intracardiac hemodynamic characteristics in high-degree mitral stenosis and an assessment of the indications for its surgical treatment].

The data from the right cardiac catheterization, echocardiography M-type and radiocardiography were juxtaposed in 54 patients with "pure" or predominating severe mitral stenosis (MS)(mitral valvular opening under 1 cm2)--confirmed at operation, in the determination of their functional and hemodynamic characteristics. The patients were grouped into three groups depending on the degree of pulmonary--capillary pressure increase (PC)--greater than 2.666, greater than 3.

[Aneurysm of the pulmonary artery].

A case with a large aneurysm of the pulmonary artery trunk is described, with a many-year course with non-elucidated-probably complex, etiology. The case was clinically and roentgelogically admitted to be the more frequently met aortic aneurysm. The diagnosis was made by means of right heart catheterization and angiocardiography.
