Ruptured aneurysms of the sinus of Valsalva.

From 1964 to 1984, 10 male and 5 female patients with ruptured aneurysms of the sinus of Valsalva (ASVs) underwent surgical correction. These procedures constituted 0.23% of the 6,350 surgical procedures that used cardiopulmonary bypass during this period. Five patients had an inflammatory condition (bacterial endocarditis, 4; syphilis, 1), and 1 had an ASV relapse 5 years after her first operation. Coexistent lesions included aortic valve regurgitation in 5 patients, ventricular septal defect in 3 (1 of whom had mitral insufficiency), patent foramen ovale in 2, and atrial septal defect in 1. Ninety-three percent were symptomatic (sudden onset of symptoms, 5 patients; gradual onset, 9 patients), commonly with shortness of breath, fatigability, chest pain, and tachycardia. The following connections occurred: noncoronary sinus to right atrium (RA) (5 patients); right coronary sinus (RCS) to RA (5 patients); and RCS to right ventricle (5 patients). There were no early or late postoperative deaths. One patient underwent reoperation after an ASV relapse. The mean follow-up period (+/- standard deviation) was 7.9 years (range, 10 months to 20.1 years). Eighty percent of the patients were found to be in New York Heart Association class I, and 20% were in class II. Apart from ASV relapse, late complications are determined by prosthetic valve dysfunction or evidence of valve disease. Early surgical intervention is justified in patients with ruptured ASV.
