Retrograde RF ablation for fascicular VT links to ostial LAD dissection in a case report.
Case Report (n=1)
No
This case highlights the rare but severe complication of selective LAD dissection during retrograde catheter ablation for ventricular tachycardia, emphasizing the need for careful catheter manipulation when crossing the aortic valve.

Signals potential ostial LAD dissection risk with retrograde fascicular VT ablation; leaves open safer approach selection.
Fascicular left ventricular tachycardia (VT) is the second most frequent idiopathic left VT in the setting of a structurally normal heart. Catheter ablation is curative in most patients with low complication rates. We report a case of ostial left anterior descending coronary artery (LAD) occlusion during fascicular ventricular tachycardia ablation. Dissection was the most likely cause of LAD obstruction. To the authors' best knowledge, this is the first case reporting selective LAD dissection during electrophysiology study with no left main coronary artery (LMCA) affection.

Kordić et al. (2017) conducted a case report in Fascicular left ventricular tachycardia (n=1). Radiofrequency catheter ablation was evaluated. Radiofrequency catheter ablation for fascicular ventricular tachycardia using a retrograde approach was complicated by an ostial left anterior descending coronary artery dissection in a 36-year-old man.
