Atrial Parasystole after Heart Transplantation

Three years after undergoing heart transplantation, a 44-year-old man presented with very frequent supraventricular extrasystoles (asterisks). Myocardial rejection and clinically significant hemodynamic alterations were excluded as causes. During an electrophysiologic study, an electrode was positioned in the right atrium of the donor heart and in the native right atrial remnant. As expected, the native atrium was beating independently of the donor atrium. However, the beats from the native atrium elicited a premature atrial depolarization in the donor heart whenever they occurred more than 190 msec after the last atrial depolarization (arrows). Apparent conduction of the cardiac impulse across the recipient–donor atrial suture line is an uncommon cause of arrhythmias after heart transplantation, and its mechanism is unknown. In this case it resulted in atrial parasystole. Changing the rate of pacing of the native atrium had no effect on this phenomenon. During follow-up, the extrasystoles persisted. Since the arrhythmia was well tolerated by the patient, no therapy was initiated.

44岁，男性，心脏移植术后3年，频繁发作室上性期外收缩（星号）。已经排除排斥反应，而且并无明显的血流动力学异常。在电生理检查中，电极安置在供心的右房和自体右房的残余部分。正如所预料的，自体心房有独立于供心之外自主跳动。但是，当自体心房的跳动发生于心房去极化（箭头）之后大于190ms时，引起了供心心房的期前收缩。通过受体-供体心脏缝合处传导的心脏冲动引起是心脏移植后心律失常的非常见原因，而且机制不清，在本病例中它导致了并行收缩。改变自体心房的起搏频率对此现象没有效果。在随访中，并行收缩一直持续，但是患者能够很好的耐受，因此并未对其进行对症治疗。
