  • Title: An unusual case of aorto-left ventricular tunnel.
    Author: Vida VL, Bottio T, Stellin G.
    Journal: Cardiol Young; 2004 Apr; 14(2):203-5. PubMed ID: 15691413.
    Abstract:
    An asymptomatic 4-year-old child was referred to our Institution with a provisional diagnosis of severe aortic valvar regurgitation in association with a ventricular septal defect. Intraoperatively, the aortic valve appeared bicuspid, and a tunnel of 7 mm diameter extending between the aorta and the left ventricle was found dividing the anterior commissure into two hemi-commissures. Repair was achieved by reconstructing the anterior commissure by direct reapproximation, and simultaneous obliteration of the aortic side of the tunnel. The aortic valvar leaflet was resuspended onto the arterial wall. This combined approach will hopefully reinforce the poorly supported aortic sinus, and may maintain aortic valvar competence over the long term. Our intraoperative diagnosis of aorto-left ventricular tunnel suggests consideration of this diagnosis when evaluating any patient with suspected aortic valvar incompetence.
