Aortico-left ventricular tunnel is a rare abnormal communication between th
e ascending aorta and the left ventricle. Early diagnosis and prompt surgic
al repair prevent congestive heart failure or consecutive valvular insuffic
iency. However, in utero diagnosis of this heart malformation has been rare
ly described and none of those children survived. We report on a case of ao
rtico-left ventricular tunnel detected at 32 weeks' gestation with a favour
able outcome after surgical repair at three months of age.
