Key result
Catheter ablation carries an up to ~2% risk of clinically significant coronary artery injury.
Why the study?
Catheter ablation is widely used for cardiac tachyarrhythmias, but coronary artery injury is one of its most significant potential complications.
Systematic Review
This systematic review outlines the incidence, mechanisms, and preventive strategies for coronary artery injury, a significant potential complication during catheter ablation of cardiac arrhythmias.
Clinicians must maintain vigilance to mitigate rare coronary injury during ablation; extends incidence estimates across modalities for future study.
Catheter ablation is a widely used treatment modality for various cardiac tachyarrhythmias, including atrial and ventricular arrhythmias. Although it is generally considered safe, the procedure carries potential complications, with coronary artery injury being one of the most significant. The aim of this systematic review was to assess the incidence, mechanisms, contributing factors, diagnostic strategies, and preventive measures related to coronary artery injury in patients undergoing catheter ablation, including radiofrequency catheter ablation, cryoablation, and pulsed-field ablation.

Hasegawa et al. (2025) conducted a systematic review in Cardiac Arrhythmias. Catheter ablation (radiofrequency, cryoablation, pulsed-field ablation) was evaluated on Incidence of coronary artery injury. Catheter ablation for cardiac arrhythmias is associated with a rare risk of clinically significant coronary artery injury, with reported incidences ranging from 0.04% to 1.7% across various modalities.
