The focus of Dr. Pass’ research is clinical electrophysiology and interventional cardiology for children and those adults with congenital heart disease. He is particularly well known for work on the topic of ablation in children having authored many papers on this topic. He has also published on the topic of channelopathy. In recent years, his interest has focused on techniques to reduce radiation exposure to patients and staff during invasive cardiac catheterizations either for interventional procedures or electrophysiology procedures. He also first authored the first large multi center US trial for the Amplatzer PDA closure device which resulted in FDA approval of what is now the most commonly implanted device for the treatment of patent ductus arteriosus.
