Arrhythmias are common problems following Mustard's operation for D-transposition of the great arteries. A 19-year-old male is presented who was diagnosed at birth with D-transposition of the great arteries and a right aortic arch and underwent a Mustard procedure at 12 months of age. He developed sinus node dysfunction and atrial flutter unresponsive to antiarrhythmic drugs and dual chamber pacing. Following complete heart block with radiofrequency catheter ablation of the atrioventricular junction, the patient's heart was paced in VVIR mode. Ventricular function improved after the ablation and persisted in two years' follow-up.
心律失常是大动脉D型转位Mustard手术后常见的问题。本文报告一名19岁男性，出生时被诊断为大动脉D型转位及右位主动脉弓，12个月大时接受了Mustard手术。他出现了窦房结功能障碍和心房扑动，对抗心律失常药物和双腔起搏均无反应。在房室交界区经射频导管消融导致完全性心脏传导阻滞之后，患者心脏以VVIR模式起搏。消融术后心室功能改善，并在两年的随访中持续存在。
