MENDEZ-SANTOS, Jesús Eduardo; OSNAYA-MARTINEZ, Héctor  e  BOBADILLA-AGUIRRE, Alfredo. Left aorto-ventricular tunnel with aortic insufficiency: Case report and literature review. Acta pediatr. Méx [online]. 2015, vol.36, n.1, pp.26-31. ISSN 2395-8235.

The left aorto-ventricular tunnel is a congenital condition that connects the ascending aorta above the sinotubular junction to the left ventricular cavity. Its incidence is 0.001% of all congenital heart disease. There are only about 130 cases reported in the literature. Although its etiology is unknown, one hypothesis is the result of a defective incorporation of bulbus cordis. The diagnosis is suspected based on physical examination and echocardiography findings. The treatment of choice is surgical trough closure of aorto-ventricular tunnel. We report the case of an 11 year old male with left aorto-ventricular tunnel with severe aortic regurgitation treated with tunnel closure at the aortic end aortic valve prosthetic replacement.
