摘要

Aortico-left ventricular tunnel is a very rare congenital heart disease. The aortic orifice of the tunnel usually situates in the right or left coronary sinus. Here we present the case of one child who had an unusual tunnel arising from the noncoronary sinus in addition to an unrestrictive perimembranous ventricular septal defect. Surgical repair was performed at 2 months of age and there was no postoperative residual lesion.
