Repair of aortico-left ventricular tunnel originating from the left aortic sinus.

Abstract

We report on a case of an 11-year-old asymptomatic child with aortico-left ventricular tunnel arising from the left aortic sinus. Preoperative transesophageal echocardiography showed a dilated aortic root with mild aortic valve incompetence and demonstrated the course of the tunnel, which originated from the left coronary sinus entering the outlet portion of the left ventricular outflow tract. Patch closure of the aortic end of the tunnel eliminated left ventricular volume overload with immediate marked reduction of cardiomegaly. At 10-month follow-up the child is asymptomatic and receiving no oral medications. Control two-dimensional Doppler echocardiography shows trivial central aortic valve incompetence.
