The management of D-loop transposition of the great arteries with left ventricular outflow tract obstruction and related forms of double-outlet right ventricle is challenging. Association with right ventricular and tricuspid valve hypoplasia and dextrocardia represents a major obstacle to achieve a biventricular repair. The most commonly used technique to deal with this condition, which is the Rastelli operation, further reduces the potentially compromised right ventricular volume due to the left ventricle-to-aorta baffle. Because the Rastelli operation risks later development of left ventricular outflow tract obstruction, aortic translocation can be considered for these patients. We report a case of double-outlet right ventricle with left ventricular outflow tract obstruction in the setting of dextrocardia, left juxtaposition of the atrial appendages, and a small tricuspid valve, which was successfully managed with a biventricular repair by means of an aortic translocation technique.
大动脉 D 型环转位合并左心室流出道梗阻及相关双出口右心室的处理具有挑战性。右心室和三尖瓣发育不良伴右旋心是实现双心室修复的主要障碍。最常用于处理这种情况(Rastelli 手术)的技术进一步减少了因左心室至主动脉分流而受损的右心室容积。由于 Rastelli 手术存在左心室流出道梗阻的潜在风险,因此可考虑对这些患者进行主动脉移位术。我们报告了一例右旋心、左心房附件并列、三尖瓣小的左心室流出道梗阻合并双出口右心室病例,成功地通过主动脉移位技术进行了双心室修复。
