Ruptured sinus of Valsalva aneurysm associated with noncompaction of the ventricular myocardium.

Rupture of a sinus of Valsalva aneurysm is a rare, but life-threatening cardiac abnormality that requires surgical correction when diagnosed, and is frequently associated with other congenital defects, particularly with ventricular septal defect, aortic valve regurgitation, and bicuspid aortic valve. We present the case of a 21-year-old man who had a ruptured aneurysm of the noncoronary sinus into the right atrium, a ventricular septal defect, a persistent left superior vena cava and a noncompaction of the ventricular myocardium diagnosed by two-dimensional echocardiography. Surgical repair was carried out and the patient made an uneventful recovery.
