Coronary sinus ablation can cause acute coronary artery occlusion, highlighting the need for ECG monitoring.
Case Report (n=2)
Radiofrequency ablation in the coronary sinus carries a risk of acute coronary artery injury, highlighting the importance of monitoring for ST elevation and understanding coronary venous anatomy.
Prompts ECG monitoring after CS ablation; leaves open true incidence in AVNRT/AVRT.
Catheter ablation of atrioventricular nodal reentrant tachycardia (AVNRT) and atrioventricular reentrant tachycardia is an established procedure with a high success rate, but procedure-related complications are not rare.1 One of the feared complications is coronary injury, the frequency of which is estimated to be ≤1%. We have recently shown that the risk of coronary artery injury is especially high when ablating in the coronary sinus (CS) branches, such as the middle cardiac vein (MCV), and the risk correlates inversely with the distance from the ideal ablation site in the CS to the coronary artery.

Garabelli et al. (2015) conducted a case report in Supraventricular tachycardia (AVNRT and preexcitation) (n=2). Radiofrequency catheter ablation in the coronary sinus was evaluated on Coronary artery injury. Radiofrequency catheter ablation within or near the coronary sinus can cause acute coronary artery occlusion, emphasizing the importance of post-ablation 12-lead ECG monitoring.
