Bronchial-to–Right Coronary Extracardiac Collateral Adjacent to the Left Pulmonary Vein Antrum: Implications for Pulsed Field Ablation
Abstract 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.
