Acute Coronary Artery Stenosis During Slow Pathway Ablation for Atrioventricular Nodal Reentrant Tachycardia in a Child

Coronary injury during radiofrequency ablation is a rare but n. potentially life-threatening complication that has been reported for attempted elimination of accessory pathways. This is the first report of coronary artery injury during slow pathway ablation for AV nodal reentrant tachycardia. Manifest signs of injury may be transient or nonexistent and easily missed. Controlled studies are needed to determine the true risk of coronary artery injury during radiofrequency ablation for supraventricular tachycardia, particularly in small children.
