About

Punam Chowdhury is a biomedical researcher whose work has advanced our understanding of catheter ablation safety, particularly in cardiac electrophysiology. Her most influential contribution, the 2008 study "Relationship Between Catheter Forces, Lesion Characteristics, 'Popping,' and Char Formation: Experience with Robotic Navigation System," has accumulated 163 citations. This landmark research used a robotic navigation system with an integrated force sensor to measure the grams of force applied to the endocardium during ablation, establishing critical relationships between catheter contact force and complications such as tissue popping, char formation, and perforation. The work provided foundational insights that helped clinicians understand how excessive force correlates with adverse lesion characteristics, directly informing safer ablation techniques. Chowdhury’s research addresses a fundamental challenge in interventional cardiology: balancing effective lesion creation with patient safety. By quantifying the mechanical forces involved in catheter ablation, her work has contributed to the development of force-sensing technologies now standard in many electrophysiology labs. More recently, she has explored interdisciplinary applications, including an AI-based security system integrating computer vision and natural language processing, demonstrating versatility beyond her primary field. Chowdhury’s contributions remain essential reading for researchers and clinicians working to improve outcomes in cardiac ablation procedures.
