Konstantinos N. Aronis, MD, PHD, FACC, FHRS, FESC, FEHRA

Board-Certified Cardiac Electrophysiologist • Expert Witness • Arrhythmia, Ablation and Device Litigation

Assistant Professor of Medicine, Johns Hopkins University

Director, ACHD Complex Ablation Program • Associate Director, VT Ablation Program

OVERVIEW

Dr. Aronis offers comprehensive electrophysiology expertise spanning the full spectrum of arrhythmia care, with particular focus on two specialized areas: complex ventricular tachycardia ablation and adult congenital heart disease electrophysiology. This combination addresses both common and challenging cases that frequently arise in litigation. As Johns Hopkins faculty performing 200+ ablation procedures annually, he maintains active clinical practice across routine and high-complexity scenarios—from standard device implantations and SVT ablations to advanced procedures including epicardial access, surgical hybrid ablations, and conduction system pacing in complex anatomy. His academic credentials include 80+ peer-reviewed publications, 3,300+ citations, and service as Associate Editor for JACC Case Reports, providing a foundation for evidence-based expert testimony. With both MD and PhD training, Dr. Aronis translates technical electrophysiology concepts into clear, accessible explanations grounded in published literature and direct procedural experience, serving both plaintiff and defense cases with objective analysis.
