Valve replacement for acute left heart endocarditis.

Abstract

Between January 1982 and June 1993, 66 patients (48 men and 18 women of mean (range) age 50 (21-77) years) underwent valve replacement for acute infective endocarditis. There were 45 aortic valve and 17 mitral valve infections. Four patients had bivalvular involvement. Fifty-three patients suffered from native valve endocarditis, with underlying valvular lesions documented for 31 patients. Staphylococci and Streptococci spp. were responsible for 68% of infection, and 20% of blood and valve cultures were negative. Refractory congestive heart failure was the leading surgical indication in 86% of patients. The mean follow-up period was 44 months. The perioperative mortality rate was 6%. Actuarial survival rates were 88.5% at 1 year and 83% at 3 years. No early recurrence of infection was noted. Six patients (9%) needed reoperation. Satisfactory results confirm that early surgical management should be considered in patients with complicated infective endocarditis.
