[Experience with orthotopic transplantation of the heart].

The improvement of cardiac transplantation outcomes has resulted, since early eighties, in a considerable annual increment in the number of the operations. Original experience with orthotopic heart transplantation is reported. Eleven transplantations were performed between 31.

[Right ventricular function in occlusion of the right coronary artery].

Hemodynamic studies at rest and under volumetric loads were carried out in 10 dogs before and after the ligation of the right coronary artery with the closed pericardium. The ligation of the right coronary artery resulted in hemodynamic signs of depressed right-ventricular function: decreased systolic blood pressure and elevated end diastolic pressure, combined with the functional curve's downward shift to the right. Total cardiac performance (minute output and mean systemic flow pressure) was also reduced.

[Emergency coronary surgery].

The authors report their experience with combined investigation and surgical treatment of patients with threatened myocardial infarction and those with postinfarction rupture of the interventricular septum. Direct reconstruction of coronary arteries was performed in 12 of 17 patients with threatened myocardial infarction (three patients died, two of cardiac complications). In the survivors, anginal signs either disappeared or became less pronounced.
