Translocation of the aortic valve for prosthetic valve endocarditis.

Abstract

Aortic prosthetic valve endocarditis is frequently associated with a perivalvular ring abscess which destroys the normal annulus, so that it is difficult to seat a new prosthesis. Between November, 1974, and January, 1980, we treated four patients with aortic prosthetic endocarditis by translocation of the aortic valve, closure of the native coronary artery ostia, and placement of saphenous vein bypass grafts to the coronary arteries. In each case operation was undertaken because of progressive congestive heart failure resulting from aortic regurgitation; two patients had systemic emboli, and two patients had uncontrolled infection. Infection was due to Enterococcus in three instances and to an unknown organism in one. Total ischemic times averaged 2 hours, 15 minutes; a 25 mm Dacron graft containing a porcine valve was used to replace the ascending aorta and aortic valve, and two or three saphenous vein grafts were placed to distal coronary arteries. One patient died 40 days postoperatively of renal failure and Pseudomonas pneumonia with an intact repair. The other three patients were hospital survivors, with one doing well until dying of chronic active hepatitis 12 months postoperatively. The other two patients are alive at 4 months and 18 months with satisfactory hemodynamic function and are free of infection. Translocation of the aortic valve for prosthetic valve endocarditis is a useful alternative when conventional replacement techniques cannot be utilized.
