Surgical Treatment of Ventricular Septal Defect and Ruptured Sinus of Valsalva Associated with Infective Endocarditis

Two patients with ventricular septal detect of Kirklin type I and ruptured right coronary sinus of Valsalva associated with infective endocarditis were operated on. Both had bacillus vegetation clinging to the aortic and pulmonary valves and the right ventricular intimal wall around the septal defect. Aortic and pulmonary regurgitation were also found. The surgical approach included vertical incision of the right ventricular outflow tract and pulmonary trunk and transverse aortotomy. The right coronary sinus of Valsalva showed distinct aneurysmal change in one patient. The aortic valve and infected Valsalva sinus were excised in both cases, and the pulmonary valve and right ventricular wall where infection extended thoroughly débrided. The resulting defect, including the ventricular septal defect and excised right Valsalva sinus and aortic annulus, was closed with one patch, and the prosthetic valve inserted in the position of the original aortic valve using this patch as part of the annulus. Both patients had a good postoperative course and are doing well, although slight pulmonary regurgitation persists.
