Prosthesing the mitral valve with preservation of the posterior cusp was performed in 156 patients. The domestic disk prostheses "Liks", "Emiks" and the bicuspid prosthesis "Medinzh" were used for the implantation. An additional correction of the tricuspid valve was made in 22 patients. The aortal valve needed the correction in 16 patients. The intrahospital lethality was 2.6%. The preservation of the posterior cusp prevents rupture of the posterior wall of the left ventricle, decreases risk of paraprosthetic fistulas and reduces frequency of the development of acute heart failure.

Rupture of the posterior wall of the left ventricle took place in 17 (1.2%) out of 1447 patients operated upon for the replacement of the mitral valve. Among them there were 13 13 early and 4 delayed ruptures. The methods used for liquidation of this complication are described. Four patients recovered (2 patients with early, 1 with a delayed rupture and 1 with a developed false aneurysm of the left ventricle). Literature data concerning the prevention of ruptures of the left ventricle and methods of their liquidation are presented.
