The aortico-left ventricular tunnel (AOLVT) is a rare abnormal communication between the ascending aorta and the left ventricle. The pathogenetic mechanism of this congenital anomaly is not completely understood. In addition to our 3 observations, 28 cases have been reported to date. In most cases the first symptoms appeared in early infancy. Clinical presentation and hemodynamics are identical to those of an aortic valve insufficiency. The correct diagnosis can be established by echocardiographic and angiocardiographic methods. Since the aortico-left ventricular tunnel is associated with congestive heart failure in infancy, in most cases surgical intervention is indicated in early childhood. The method of choice for surgical correction is a patch closure of the aortic orifice of the tunnel.
主动脉左心室通道（AOLVT）是升主动脉与左心室之间一种罕见的异常交通。这种先天性畸形的发病机制尚未完全明了。除我们观察到的3例病例外，迄今已报道了28例。大多数病例的首发症状出现在婴儿早期。临床表现和血流动力学与主动脉瓣关闭不全相同。通过超声心动图和心血管造影方法可做出正确诊断。由于主动脉左心室通道在婴儿期与充血性心力衰竭相关，多数情况下在儿童早期即需进行手术干预。手术矫正的首选方法是用补片封闭通道的主动脉口。
