Subclinical Coronary Atherosclerosis in Patients Undergoing Catheter Ablation for Idiopathic Premature Ventricular Complexes

Abstract

Objective: Idiopathic premature ventricular complexes (PVC) occur in the absence of clinically apparent structural heartdisease (SHD) and are treated effectively with catheter ablation. We aimed to evaluate the association of PVC characteristicswith subclinical coronary artery disease (CAD) during catheter ablation.Methods: A total of 116 patients (age: median 55 years; sex: 58.6% men), without SHD, in whom PVC ablation and coronaryangiography had been performed simultaneously were enrolled. PVC localizations were categorized into 4 groups as; rightventricular outflow tract (RVOT), left ventricular outflow tract (LVOT), left ventricle (LV)-body, and right ventricle (RV)-body.PVC frequency was also classified as moderate (5,000–10,000 PVCs/day) and frequent (≥10,000 PVCs/day). Coronary arterystenoses were categorized as normal, non-critical (
