Key result
Radiofrequency catheter ablation for premature ventricular complexes in a 66-year-old female resulted in severe left main coronary artery stenosis requiring coronary artery bypass grafting.
Why the study?
Despite careful attention to avoiding coronary arteries during radiofrequency catheter ablation for premature ventricular complexes, coronary injuries may still occur.
Case Report (n=1)
No
This case highlights a rare but severe complication of catheter-induced left main coronary artery stenosis during PVC ablation, which was successfully managed with CABG.
Coronary injury can occur during PVC ablation despite precautions; this case leaves open optimal safety strategies for future procedures.
Many patients with premature ventricular complexes (PVCs) do not experience symptoms. However, for those with frequent or symptomatic PVCs, medical interventions are available. If medications fail, radiofrequency catheter ablation may be performed. Despite careful attention to avoiding the coronary arteries during ablation, injuries may still occur. Here, we present the case of a 66-year-old Caucasian female with frequent PVCs causing worsening palpitations, chest pain, fatigue, and lightheadedness, who underwent elective PVC ablation and suffered catheter-induced left main coronary artery stenosis, necessitating subsequent coronary artery bypass grafting (CABG). This case highlights a rare complication of cardiac ablation in the setting of PVCs and the rationale for clinical decisions made throughout the patient's hospital course.

Schaar et al. (2024) conducted a case report in Premature ventricular complexes (n=1). Radiofrequency catheter ablation was evaluated on Catheter-induced left main coronary artery stenosis. Radiofrequency catheter ablation for premature ventricular complexes in a 66-year-old female resulted in severe left main coronary artery stenosis requiring coronary artery bypass grafting.
