Why the study?
Does ablative therapy improve long-term sinus rhythm maintenance in patients with congenital heart disease and postoperative atrial tachyarrhythmia?
Does ablative therapy improve long-term sinus rhythm maintenance in patients with congenital heart disease and postoperative atrial tachyarrhythmia?
In CHD patients with postoperative atrial tachyarrhythmia, recurrent ATs often originate from new locations rather than previous ablation lesions, and while repeat ablations are frequently needed, most patients ultimately maintain sinus rhythm.
No takes yet. Share an insight, caveat, or question.
Repeat ablation may sustain sinus rhythm in CHD with postoperative AT; leaves open optimal lesion strategies.
Groot et al. (2010) studied this question.
