title: [Triple valve replacement. Evaluation of 90 surgically treated patients].
abstract: Ninety patients, aged 17 to 59 years (average 39.8 yrs) underwent triple valve replacement from January 1967 to December 1979. The aetiology was rheumatic carditis in 84% of cases. There had been previous surgery in 29 cases (19 mitral commissurotomies). All patients were severely symptomatic: 68 (76%) had atrial fibrillation and the cardiothoracic ratio was 0.70 +/- 0.085. In 24 cases, triple valve stenosis (aortic, mitral and tricuspid) was observed; 13 patients had triple regurgitation and 53 patients had mixed lesions (stenosis and regurgitation). Triple mechanical valve prostheses were implanted in 35 cases (Björk or Starr), triple bioprostheses were implanted in 12 cases, and 43 patients received a combination of mechanical and bioprostheses (tricuspid bioprostheses in all 43 cases). The patients were divided into two groups according to the type of valve replacement; Group I: 57 patients, subdivided into Group IA (35 cases, 39%) with triple mechanical prosthesis, and Group IB (22 cases, 25%) with mechanical aortic and mitral valve prostheses and tricuspid bioprostheses; Group II, 33 patients, subdivided into Group IIA (12 patients, 13%) with triple bioprostheses, and Group IIB (21 patients, 23%) with mitral and tricuspid bioprostheses and a mechanical aortic valve prosthesis. Techniques of myocardial protection have have improved since the beginning of this series and at present comprise cardioplegia associated with general hypothermia to 25 degrees C and pericardial irrigation with ice cold saline. The overall operative mortality was 37% (34/90) but in 1979 alone it was only 10%.(ABSTRACT TRUNCATED AT 250 WORDS)
