EP09.31: Prenatally diagnosed aorta‐left ventricular tunnel

We share very rare conditions that have been demonstrated during the fetal period in a fetus 27 weeks referred to our center for suspicion of dilated aorta. After detailed fetal echocardiography, our opinion was an aorta-left ventricular tunnel with an enlarged heart without cardiac failure. Aorto-left ventricular (LV) tunnel (ALVT) is a rare congenital communication between the ascending aorta and the left ventricle. Aorto-LV tunnel is an abnormal paravalvular communication between the ascending aorta and the left ventricle that creates a bidirectional flow of blood from the aorta to the left ventricle. The aortic origin of the tunnel may be situated anywhere above the aortic sinus. The size and the shape of ALVT are variable. The tunnel ventricular orifice opens into the left ventricular cavity as in the majority of cases at the level of the fibrous triangle. The etiology of aortic-ventricular tunnel is unknown. This spectrum may reflect variables according to associated malformations. During the feta period, we followed every three weeks, and at 38 weeks baby was delivered due to severe cardiac failure. On the second day of life, neonatal echocardiography and CT-angio confirmed our prenatal diagnosis. Third day of life baby was operated on successfully. 15 months later, he is still doing well recovering a completely normal cardiac function.
