Aortico-left ventricular tunnel: collective review

Abstract

Aortico-left ventricular tunnel (ALVT) is an extremely rare congenital entity in which an abnormal communication between the aorta and the left ventricle bypasses the aortic valve. The condition usually results in gross aortic regurgitation, rapid cardiac decompensation, and death. An additional case of ALVT managed by successful surgical repair is described. The 38 cases reported in the literature are reviewed with emphasis on the clinical and pathological features, diagnosis, natural history, and management. Early operation is recommended to prevent distortion of the aortic valve, dilatation of the left ventricle, and distortion of the aortic anulus.
