    Abstract:
    BACKGROUND: We reviewed our experience with congenital ruptured sinus of Valsalva aneurysms (RSVA) to determine risk factors influencing occurrence and postoperative worsening of aortic regurgitation (AR). METHODS: Over an 11-year period, 210 patients (33 ± 9.7 years old) underwent surgical repair of RSVA. Aneurysm originated from the right noncoronary sinus and other sinuses in 171, 35 and 4 patients, respectively; and ruptured into right ventricle outlet tract in 115 patients, right ventricle in 16, right atrium in 75, and other chambers in 4. Aortic regurgitation (111) and ventricular septal defect (108) were common coexisting anomalies. Patch closure of RSVA was performed in 61 patients, direct sutures in 18 patients, patch closure plus direct sutures in 88 patients, and repair simultaneous with aortic valve replacement in 43 patients. RESULTS: All but one patient survived the operation. In early postoperative periods, AR improved in 26 patients and worsened in 23. In 114 late follow-up patients with echocardiographic assessment, 18 showed deteriorated AR. By logistic regression analysis, RSVA ruptured into the right ventricle outlet tract and secondary changes of the aortic valve were risk factors for preoperative AR, and RSVA repaired with direct sutures had a significantly higher incidence of early worsening of AR. By Cox regression analysis, AR at discharge was an independent risk factor for late follow-up AR worsening. CONCLUSIONS: The RSVA can be repaired with a low mortality and excellent long-term result. An early, aggressive treatment should be recommended to prevent postoperative AR, and a direct-suture closure of RSVA should be avoided to prevent early worsening of AR.
