Abstract
A report is presented of 50 men and 31 women, mean age 50.3 years, who underwent surgery for multivalvular cardiac disease in 1973–1987. NYHA function class was III-IV in 88% of the patients. The most common procedures were aortic + mitral valve replacement (81%), aortic + mitral valve replacement + coronary artery bypass grafting (5%), aortic valve replacement + tricuspid valvuloplasty (5%) and mitral valve replacement + tricuspid valvuloplasty (5%): 95% of the implanted valves were of Björk-Shiley disc type. Nine patients died perioperatively, six due to myocardial infarction and/or low cardiac output. Postoperative bleeding necessitated resternotomy in three cases. Follow-up was complete, with a mean observation time of 4.5 years (a total of 323 patient years). The incidence of thrombotic valve encapsulation was 0.6/100 patient years. Corresponding figures for anticoagulant-related haemorrhage, prosthetic valve endocarditis and paraprosthetic leakage were 0.9, 1.2 and 1.2. In our experience, the rate of late complications after multivalvular reconstruction using Björk-Shiley prosthesis is acceptable if anticoagulant therapy is correctly employed.
