A Case Report of Coronary Artery Stenosis Induced by Ablation for Premature Ventricular Complexes

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.
