Key result
Catheter ablation targeting the ridge successfully terminated ridge-related reentry in all 5 patients who developed this arrhythmia after circumferential pulmonary vein isolation and LMI ablation.

Does catheter ablation targeting the ridge terminate ridge-related reentry in patients with prior pulmonary vein isolation and lateral mitral isthmus ablation?
Ridge-related reentry is a variant of perimitral atrial tachycardia that can develop after pulmonary vein isolation and lateral mitral isthmus ablation, and it can be successfully treated with targeted catheter ablation of the ridge.
Takatsuki et al. (2013) conducted an observational in Atrial fibrillation (n=61). Catheter ablation targeting the ridge was evaluated on Termination of ridge-related reentry. Catheter ablation targeting the ridge successfully terminated ridge-related reentry in all 5 patients who developed this arrhythmia after circumferential pulmonary vein isolation and LMI ablation.
