Delayed manifestation of severe coronary artery injury/stenosis associated with cavo-tricuspid isthmus ablation: a case report

Physicians should consider the possibility of CAI associated with RFA procedures involving ablation near the coronary arteries (CAs) in patients presenting with chest discomfort after RFA, even when the presentation is remote from the index procedure. Unanticipated anatomic variations can predispose to CAIs. Therefore, awareness of the relationship between CA course and anatomical ablation site before RFA may be important to prevent CAIs and improve procedural safety.
