Missing pouches in high-density mapping of atrial tachyarrhythmia in congenital heart diseases.

ABSTRACT:

Background

The use of high-density electroanatomical mapping in the Chinese population for congenital heart disease (CHD) is not well reported.

Methods

Retrospective review of consecutive transcatheter ablation of atrial tachyarrhythmia using high-density mapping for CHD patients (at least moderate complexity) in the only tertiary congenital heart center in the territory from January 2017 to January 2019 was conducted. Orion mapping catheter in Rhythmia system (Boston Scientific) was used to create activation and voltage maps. Parameters including mechanism of arrhythmia, acute success, and follow-up data were recorded.

Results

Eight patients were identified (median age 35.5 years) who underwent transcatheter ablation of atrial arrhythmia. More than one reentry circui
