This report presents an experience with 44 children, including 9 less than 5 years of age, who were operated upon for replacement of a cardiac valve. Our early operative mortality was 60%, whereas in the past 4 years it has been only 30%. We have operated only on significantly symptomatic children for whom no other therapy was available. From our experience, we cannot judge the necessity of anticoagulants. No patients have required a second operation because the valve has been outgrown, although several patients who underwent mitral valve replacement have had postoperative gradients across the prosthesis.
