[Surgical repair of aortico-left ventricular tunnel, a case report]

Aortico-left ventricular tunnel is an extremely rare congenital heart disease. Although there are dozens of English-written literature about this condition, we could not find any report in Japanese. Our patient was a boy whose illness was diagnosed as aortico-left ventricular tunnel when he was three years old. Soon after the diagnosis was made he underwent surgical correction. The orifice of tunnel was closed using EPTFE patch at the aortic side and at the left ventricular side was closed directly. Postoperatively moderate degree of aortic valvular regurgitation was remained. Three years after the surgical correction, now the boy is six years old and doing well. But we anticipate that he man need aortic valve replacement in the near future.
