Left ventricular apical-abdominal aortic valved conduit has been a successful procedure for relief of severe left ventricular outlet obstruction. Postoperatively, unusual deformities of the gastric fundus and cardia may be seen on the upper gastrointestinal series and should not be mistaken for pathologic mass lesions. Three deformities are characteristic: anterior impression on the gastric fundus, medial impression on the gastric fundus, and narrowing of the distal esophagus. Occasional gastrointestinal complications including dysphagia and gastric erosion may occur.
左心室心尖-腹主动脉带瓣管道术是缓解严重左心室流出道梗阻的一种成功手术。术后，上消化道造影可能会显示胃底和贲门的异常畸形，不应将其误诊为病理性肿块病变。有三种畸形较为典型：胃底前部压迹、胃底内侧压迹以及食管远端狭窄。偶尔可能会出现包括吞咽困难和胃糜烂在内的胃肠道并发症。
