Aortico-left ventricular tunnel, an unusual congenital cardiac anomaly in adult: application of a new operative technique.
Aortico-left ventricular tunnel is a rare congenital cardiac anomaly. A 45-year-old man was referred to our clinic with unstable angina pectoris. The patient had an aortico-left ventricular tunnel that had been operated on 15 years before and that now showed a recurrence. We performed a new surgical technique, including closure of orifices of the tunnel by resection of the aorta at the left coronary ostium, reconstruction of the aorta with patch plasty, and formation of a neo-left main branch by applying a saphenous magna vein patch at the noncoronary cusp. In this technique, the possibility of aortic regurgitation caused by stretching and distortion of the aortic ring and leaflets by primary suture closure of tunnel is eliminated. The postoperative 2-D colored Doppler echocardiography and cardiac MRI showed an excellent result of the procedure. Coronary flow could be restored, and thus anginal symptoms disappeared.
