[Surgical treatment of combined valvular disease in 680 patients].
Between 1982 and May 1993, we operated on 680 patients with combined valvular disease. Previous operations were including closed mitral commissurotomy in 87, and bioprosthetic valve replacement in mitral position in 15. The types of combined valve disease included mitral valve disease combined with functional tricuspid regurgitation (FTR) (245), with organic tricuspid disease (OTD) (10); mitral and aortic disease (258), combined with FTR (128), and with OTD (39). The early mortality was 4.7% in total 2.4% and 6.1% respectively in MVR or DVR plus tricuspid procedures. The main cause of early death was low cardiac output syndrome. The late mortality was 2.6% pt-yr, congestive heart failure and coagulant-related hemorrhage were the predominant causes of late death. We considered that FTR is the outcome of right ventricle decompensation, while tricuspid valve must be actively inspected intraoperatively, and must be corrected completely. OTD can be successfully repaired in most patients. Myocardial protection should be emphasized, and continuous perfusion of cold blood cardioplegia and controlled reperfusion of warm blood contained mannitol have marked effect.
