Abstract
Fifteen patients of active infective endocarditis (IE) (group A) and 22 patients of inactive IE (group I) were surgically treated in Kyushu University Hospital. Early mortality was 6.7% (1/14) in group A and 0% in group I. Actuarial survival rate was 72.4±11.7%, 21.1±24.8% in group A and 100±0% (p<0.01), 100±0% (p<0.001) in group I at 1 and 5 years after operation, respectively. Five patients required reoperation in group A because of periprosthetic leak (3), prosthetic valve IE (1) and thrombosed valve (1). At 5 years the freedom from reoperation was 64.3±12.8% in group A and 94.7±5.1% (p<0.02) in group I. Thus, in comparison with inactive cases, late results of surgical treatment for active IE were less satisfactory.
