title: Ventricular tachycardia secondary to aneurysm of sinus of Valsalva.
abstract: A patient with unruptured aneurysm of the sinus of Valsalva presented because of ventricular tachycardia refractory to medical therapy. The underlying problem was not suspected until cardiac catheterization. Once the aneurysm was repaired, the tachycardia was abolished; the patient required no antiarrhythmic drugs. Two points are emphasized: First, cardiac catheterization is often indicated early in cases of ventricular tachycardia without obvious cause. Second, recurrent ventricular tachycardia is a hitherto unreported but important complication of sinus of Valsalva aneurysm.
