Right ventricular (subaortic) obstruction has only rarely been described in complete transposition of the great arteries. five patients with complete transposition of the great arteries in whom subaortic stenosis was angiocardiographically demonstrated were studied. All had a pressure gradient of 30 to 55 mm Hg across the aortic outflow tract. Two of the patients manifested mild tricuspid insufficiency, and another two had coarctation of the aorta. The etiologic, anatomic, hemodynamic and prognostic aspects of this unusual anomaly are discussed. An angiocardiographically demonstrated series of this anomaly has not been reported on before.
右心室（主动脉下）梗阻在完全性大动脉转位中仅有极少的病例报道。本文研究了5例经心血管造影证实存在主动脉下狭窄的完全性大动脉转位患者。所有患者在主动脉流出道的压力阶差为30至55毫米汞柱。其中2例患者表现为轻度三尖瓣关闭不全，另外2例患有主动脉缩窄。本文讨论了这种罕见异常的病因、解剖、血流动力学及预后等方面。此前尚未见关于该异常经心血管造影证实的系列报道。
