Abstract

The clinical course of 22 patients with acute endocarditis treated surgically less than six weeks after the onset of antibiotic therapy was reviewed. The aortic valve was infected in 13 patients, the mitral in six, the tricuspid in two, and one patient had both aortic and mitral valve involvement. The indications for surgical intervention before the completion of adequate antibacterial therapy included uncontrollable congestive heart failure, persistent sepsis, systemic embolization, and multiple septic pulmonary embolizations. The annulus was involved by the infectious process in five of the 13 patients with aortic valve endocarditis, in one of the two patients with tricuspid valve infection, and in none of the patients with mitral valve endocarditis. There were two surgical deaths, for a mortality of 9.1%. During the follow-up period, four patients died three months, seven months, four years, and seven years after surgery. The remaining patients have been followed up for a period of five months to 10 years. One patient has a hemodynamically insignificant paravalvular leak, and another developed paravalvular regurgitation and a false aneurysm of the left sinus of Valsalva two weeks after the initial operation. She subsequently underwent successful valve replacement and repair of the aneurysm. This study confirms that valvular replacement should be done for acute endocarditis as soon as indicated, and that the incidence of reinfection and/or the development of valvular or paravalvular problems is small even in the patients with incomplete antimicrobial therapy, whether or not the annulus is involved by the infectious process.
