[Surgical treatment of mitral and tricuspid valve defects].

The results of surgical treatment of 265 patients with mitral-tricuspid valvular diseases are analysed. The operations were carried out in the period from Jan. 1, 1977 to Jan. 1, 1990 with various plastic procedures on the tricuspid valve. Hospital mortality was 13.2%. The late-term results were studied in follow-up periods of 6 months to 12 years in 207 (90%) patients. The results were good in 187 (75.9%), satisfactory and poor in 28 (13.5%) patients; 22 (10.6%) patients died. With the hospital losses taken into account, 5-year survival came to 73% and 10-year survival to 54%. Stability of good postoperative results was 79% by the 5th year and 49% by the 10th year. Among the surviving patients 85% are related to functional classes I and II and lead an active life. Plastic operations on the tricuspid valve can be undertaken in 92% of patients with mitral-tricuspid valvular diseases; they produce good late-term results in most cases, ensure stable normalization of hemodynamics, and should be performed more often in clinical practice.
