Ruptured Valsalva Sinus Aneurysm with Ventricular Septal Defect and Double-Chambered Right Ventricle without Heart Failure: A Case Report.

Valsalva sinus aneurysm and double-chambered right ventricle are both rare congenital cardiac anomalies. Ventricular septal defect may be present in approximately 50%-60% of patients with Valsalva sinus aneurysm or approximately 70%-80% of patients with double-chambered right ventricle. However, Valsalva sinus aneurysm, double-chambered right ventricle, and ventricular septal defect rarely coexist in the same patient. As these diseases progress, patients often complain of symptoms of heart failure, due to the shunt flow. The case of a patient with Valsalva sinus aneurysm, double-chambered right ventricle, and ventricular septal defect without symptoms of heart failure had never been reported until now.
