Abstract

INTRODUCTION

Atrial tachyarrhythmias (AT) frequently develop later after a Fontan operation and can be successfully treated by ablative therapy. However, new arrhythmias often develop.

METHODS AND RESULTS

Consecutive AT emerging in a Fontan patient were ablated using three-dimensional electro-anatomical mapping. During a 6-year period, nine different AT were ablated, including intraatrial reentrant AT (N=5), focal AT (N=3), and focal atrial fibrillation (N=1) originating from distinct right atrial sites.

CONCLUSION

In a Fontan patient, successive AT can be caused by different mechanisms. These AT are most likely the result of progressive atrial cardiomyopathy and can be treated by catheter ablation.

摘要

引言

房性快速性心律失常（AT）常在Fontan手术后较晚出现，可通过消融治疗成功治愈。然而，新的心律失常常复发。

方法与结果

使用三维电解剖标测对一名Fontan患者连续出现的AT进行消融。在6年期间，共消融了9种不同类型的AT，包括源于不同右心房部位的房内折返性AT（n = 5）、局灶性AT（n = 3）和局灶性心房颤动（n = 1）。

结论

在一名Fontan患者中，连续发生的AT可能由不同机制引起。这些AT很可能是进行性心房心肌病的结果，可通过导管消融治疗。
