Surgical repair of a ruptured congenital sinus of Valsalva aneurysm: 10-year experience with 286 cases.

Abstract

Surgical intervention is the main treatment for a ruptured congenital sinus of Valsalva aneurysm (SVA). However, reports on the surgical experience are scarce. We retrospectively analysed the cases of our centre to summarize our 10-year experience. A total of 286 patients who were diagnosed with a congenital ruptured SVA and underwent surgical repair between 2007 and 2016 were identified for the analysis. Follow-up data (mean ± standard deviation: 49.6 ± 34.9 months) were obtained from outpatient department records and telephone calls. The SVAs originated from the right coronary sinus (79.7%), the non-coronary sinus (19.6%) and the left coronary sinus (0.7%) but ruptured into the right ventricle (58.4%) and the right atrium (41.3%). The most commonly associated deformities were a ventricular septal defect (46.3%), aortic valve regurgitation (33.2%) and tricuspid regurgitation (20.3%). The SVA defect was closed by direct suturing (9.1%) or patching (90.9%) through an incision in the cardiac chamber involved or a transaortic approach. The mean postoperative hospital stay duration was 7.2 days, and 98.6% of the patients were discharged in New York Heart Association functional class I or II. The incidence rate of short-term complications was 5.7%. There were 4 late deaths, and 9 patients required rehospitalization due to surgery-related events. The estimated 10-year survival rate was greater than 90% according to the Kaplan-Meier survival curve. Surgical repair is an effective and safe treatment for a ruptured SVA. The majority of patients who undergo surgical repair can survive for a long time.
