Effects of Age‐Related Aortic Root Anatomic Changes on Left Ventricular Outflow Tract Pace‐Mapping Morphologies: A Cardiac Magnetic Resonance Imaging Validation Study

Abstract

The anatomy of the aortic root changes with age, and age-related aortic root changes may affect the QRS morphology during pace-mapping. Understanding the potential anatomic changes that accompany aging is important to maximize the efficacy of catheter ablation of OT VAs.
