Answer:
AORTO LEFT VENTRICULAR TUNNEL
Findings:
Echo shows an ALVT arising immediately above the right sinus of Valsalva Long-axis view of the tunnel shows Diastolic regurgitation via the tunnel. CECT CORONARY ANGIOGRAPHY AXIAL,SAG IMAGES SHOWS - a tunnel originating from the aorta just above the right coronary sinus and coursing posteriorly around the aorta and traversing thr’ IVseptum and terminating into the superiormost part of left ventricle just below the aortic annulus & dilated LV.
Discussion
Aorto-left ventricular tunnel is a rare congenital, extracardiac channel which connects the ascending aorta above the sinutubular junction to the cavity of the left ventricle. INCIDENCE < 0.1% SEX - M:F=2:1 Associated defects, involving the prox.coronary arteries, or aortic or pulmonary valves, present in <50% cases.
