We report a case of a 15 month-old boy who underwent the arterial switch operation using cryopreserved aortic homograft for transposition of the great arteries with pulmonary regurgitation, with coexisting right ventricular outflow tract obstruction precluding atrial switch operation. Follow-up echocardiography at 6 months showed trivial neoaortic valve regurgitation, no significant systemic outflow obstruction, with good cardiac function. In small children, the choice of material for left ventricular outflow tract reconstruction is one of the most crucial issues. Cryopreserved homograft has been one of the primary options for the aortic valve replacement in small children because of the ease of suturing and excellent hemostasis.
我们报告一例15个月大的男孩，其因大动脉转位合并肺动脉反流接受了使用低温保存主动脉同种异体移植物的动脉调转手术，同时并存的右心室流出道梗阻排除了心房调转手术。6个月时的随访超声心动图显示新主动脉瓣微量反流，无明显体循环流出道梗阻，心脏功能良好。在小儿中，左心室流出道重建材料的选择是最关键的问题之一。由于缝合简便且止血效果极佳，低温保存同种异体移植物一直是小儿主动脉瓣置换的主要选择之一。
