Valve replacement in the young patient with rheumatic heart disease. Review of a twenty-year experience.

During a 20-year period 303 young subjects between 9 and 20 years of age (mean, 16.2 +/- 2.72 years) with rapid and relentlessly progressive valvular disease from rheumatic fever underwent valve replacements. The Starr-Edwards ball valve prosthesis remains the device of choice, although other valves have been implanted. The overall hospital mortality rate was 9.6% in the mitral valve, 3.5% in the aortic valve, and 4.2% in the double valve replacement groups. Actuarial survival at 10, 15, and 20 years was 78.4% (+/- 3.3%), 70.0% (+/- 5.8%), and 59.3% (+/- 11.1%), respectively, for patients with mitral valve replacement. The rates for aortic valve replacement were 85.9% (+/- 4.6%) at 10 and 15 years and 72.7% (12.8%) at 20 years. In the double valve replacement group the survival rates after 5 and 10 years were 79.9% (+/- 5.1%). The incidence of thromboembolism was 0.41, 0.59, and 1.04 per 100 patient-years for the mitral, aortic, and double-valve prostheses, respectively. The prospect of childbearing seems promising in those young women who were subsequently married. Our favorable and gratifying experience in this review bears testimony to the physiologic advantages of the Starr-Edwards valve as the device of choice in the rehabilitation of patients with advanced and severe valvular disease after rheumatic fever.
