Ben Sieniewicz

Dr. Ben Sieniewicz is a cardiac electrophysiologist and researcher specializing in advanced cardiac resynchronization therapy (CRT) techniques with 588 citations across 26 publications. His work focuses on improving outcomes for heart failure patients through novel pacing approaches including endocardial pacing and left bundle branch area pacing.

Dr. Sieniewicz completed his doctoral thesis titled 'Optimal site selection & guidance during endocardial Cardiac Resynchronisation Therapy' in September 2019 under the supervision of Professor Reza Razavi. His research fingerprint shows strong specialization in Cardiac Resynchronization Therapy (100%), Endocardium (38%), Hemodynamics (27%), and Congestive Heart Failure (26%).

His research program investigates the electrophysiological mechanisms and clinical benefits of novel pacing strategies compared to conventional approaches. Recent work demonstrates how left bundle branch area pacing reduces epicardial dispersion of repolarization and provides hemodynamic advantages over traditional biventricular CRT. He frequently employs multimodal imaging techniques including cardiac magnetic resonance imaging and electrocardiographic imaging to understand pacing mechanisms.

Dr. Sieniewicz collaborates extensively with a research network led by Professor Christopher Rinaldi and Professor Reza Razavi, conducting both mechanistic studies and clinical trials like the STRIVE HF trial. His work analyzing healthcare costs of lead extraction contributes to efficient resource allocation within medical systems.
