Pre-emptive PCI enables safe PFA by avoiding a bronchial-to-right coronary collateral near the pulmonary vein.
Pre-emptive PCI of a right coronary CTO can enable safe pulsed-field ablation in patients with critical extracardiac collaterals near the pulmonary vein antrum.

Highlights a rare anatomical risk of collateral damage during pulsed-field ablation; leaves open.
Right coronary chronic total occlusion was incidentally identified in a 67-year-old man scheduled for pulsed-field ablation for paroxysmal atrial fibrillation. The occluded territory was supplied by collateral flow via a bronchial-to-right coronary extracardiac collateral in close proximity to the left pulmonary vein antrum. Pre-emptive percutaneous coronary intervention to avoid reliance on this collateral enabled safe ablation.
