[Current problems and achievements of cardiosurgery at the Leningrad Medical Institute for Postgraduate Training of Physicians].

The authors analyse the experience with the surgical treatment of about 3000 patients with different forms of cardiac pathology and general lethality in 4,1% of cases. Favorable results were obtained following operations in children of the first three years of life with the open arterial duct, in 4 to 6-year-old children with coarctation of the aorta. The authors show expediency of correction of septal defects before severe disturbances of hemodynamics could develop. The closed method of correction is indicated in non-complicated forms of mitral stenosis. Patients with complicated forms of mitral stenosis, mitral insufficiency should be operated upon under conditions of artificial blood circulation.
