AbstractFrom 1967 to 1993, 21 patients underwent surgical repair of aortic left ventricular discontinuity as a result of acute bacterial endocarditis. Repair of the defect between the aorta and left ventricle was usually with interposition of a patch (prosthetic patch or autologous pericardium), using a continuous monofilament suture. Interrupted pledgetted stitches were used when the ventricular tissue appeared friable. A valve prosthesis was then sewn to the patch and remaining annulus. Three patients died in the immediate perioperative period. Long follow-up ranging from 5 to 142 months (mean 36 months) is available on 17 of 18 survivors. There were six deaths in this group from 11 to 142 months (mean 67 months) from initial surgery. Of 11 long-term survivors (5 to 61 months (mean 21 months) after operation), nine have had event-free courses. Two cases of recurrent subacute bacterial endocarditis occurred 3 and 52 months after surgery in patients who were intravenous drug abusers, both of whom were managed medically. It is concluded that while aortic left ventricular discontinuity remains a potentially lethal complication of acute bacterial endocarditis, débridement of infected necrotic tissue, patch repair of the defect, and prosthetic valve replacement offer satisfactory immediate and late results.
