Key result
Left free wall RF ablation triggers acute remote proximal LAD occlusion, successfully treated with stenting.
Why the study?
Complications of radiofrequency ablation for WPW syndrome are unusual and acute coronary artery occlusion is very rare.
Case Report (n=1)
Acute coronary artery occlusion is a rare but possible complication of radiofrequency ablation for WPW syndrome, even at sites remote from the ablation, and can be managed with intracoronary stenting.
Rare remote LAD occlusion during left-sided pathway ablation warrants procedural vigilance; leaves open incidence, mechanisms, and prevention strategies.
Radiofrequency (RF) ablation of accessory bypass tracts associated with the Wolff-Parkinson-White (WPW) syndrome has become the treatment of choice for many arrhythmias. Complications are unusual and acute coronary artery occlusion is very rare. We here present a 38-year-old male patient with an acute occlusion of proximal left anterior descending (LAD) coronary artery after RF ablation of a left free wall accessory pathway. An interesting feature is the site of the coronary artery occlusion which is remote from the RF application site. The occlusion was successfully treated with the placement of an intracoronary stent.

Yıldız et al. (2014) conducted a case report in Wolff-Parkinson-White (WPW) syndrome (n=1). Radiofrequency (RF) ablation was evaluated on Acute occlusion of proximal left anterior descending (LAD) coronary artery. Radiofrequency ablation of a left free wall accessory pathway was complicated by an acute occlusion of the proximal LAD coronary artery remote from the ablation site, successfully treated with a stent.
