Primary anatomical repair of TGA has several theoretical advantages over conventional atrial baffle techniques. However, one of the most common postoperative complications of the new technique is the development of an obstruction at the arterial anastomosis to the pulmonary artery (PA). A supravalvular pulmonary stenosis developed progressively over the first months after an arterial switch operation of a simple TGA in a newborn infant. The diagnosis was easily performed by Doppler-echocardiographic follow-up studies. Hemodynamic assessment by cardiac catheterization performed when the patient was five months old revealed a systolic gradient of 76 mm Hg at the arterial anastomosis. Percutaneous balloon angioplasty was successfully performed.
与传统心房内板障技术相比，大动脉转位（TGA）的一期解剖修复具有若干理论优势。然而，新技术最常见的术后并发症之一是在肺动脉（PA）动脉吻合处出现梗阻。一名新生儿单纯TGA行动脉调转手术后的头几个月，逐渐出现了瓣上肺动脉狭窄。通过多普勒超声心动图随访研究很容易做出诊断。患者5个月大时进行的心导管检查血流动力学评估显示，动脉吻合处的收缩期压差为76毫米汞柱。成功实施了经皮球囊血管成形术。
