Background: Aneurysms of sinus of Valsalva are rare. Here, we analyze retrospectively patients operated on at our center during the last 20 years.
Patients and methods: One hundred four cases of congential aneurysm of sinus of Valsalva were operated upon between January 1977 and April 1996. Only 12 aneurysms were unruptured. The majority (76.9%) arose from the right coronary sinus. The right ventricle was the most common chamber of rupture (58.6%). Ventricular septal defect was associated in 46 patients (44.2%), of which 28 (60.9%) were supracristal. Ventricular septal defect was more common in aneurysms arising from the right coronary sinus (91.3%). Aortic incompetence was found in 45 patients (43.3%). The defect was closed through the aortic root alone in 24 patients (23.1%) and through both the aortic root and the chamber of rupture in the remaining 80 patients. Six patients underwent aortic valve repair, and 21 an aortic valve replacement.
Results: There were two hospital deaths (1.92%). Morbidities were few. Follow-up ranged from 1 to 20 years (mean 8.2 +/- 1.1). There was one late noncardiac death, and in the majority, the long-term follow-up was uneventful.
Conclusion: Surgery for aneurysm of sinus of Valsalva yields gratifying results, and it should be undertaken as soon as the condition is diagnosed.
