Key result
High-density 3D mapping and RF ablation successfully terminate posterior LA wall tachycardia post-AF ablation.
High-density 3D mapping can successfully localize and guide safe radiofrequency ablation of rare atrial tachycardia originating from the left atrial posterior wall after prior AF ablation.
No takes yet. Share an insight, caveat, or question.
May aid localization of rare post-ablation tachycardias; leaves open generalizability beyond this case.
Gong et al. (2026) studied this question. High-density 3D mapping accurately localized posterior left atrial wall atrial tachycardia post-AF ablation, with radiofrequency ablation promptly terminating tachycardia and 3-month symptom-free foll.
