Unruptured aneurysm of the sinus of Valsalva presenting with ventricular tachycardia.

We report a case of a large unruptured aneurysm of the right sinus of Valsalva which caused severe right ventricular outflow tract obstruction and presented dramatically with a life threatening ventricular tachycardia. Despite severe aortic incompetence prior to surgery it was possible to resect the aneurysm and repair the aortic root without resort to aortic valve replacement and thus return the anatomy to normal.
