About

Prapa Kanagaratnam is a prominent cardiac electrophysiologist whose research has significantly advanced the field of robotic catheter ablation, particularly in the treatment of atrial fibrillation and ventricular tachycardia. Working at the intersection of interventional cardiology and emerging robotic technologies, Kanagaratnam has been a pioneering figure in evaluating the safety, efficacy, and technical capabilities of remotely steerable catheter systems for cardiac arrhythmia management. His most influential contribution, a 2008 paper accumulating 176 citations, introduced clinicians to the first human experiences with robotic catheter ablation using a novel steerable guide sheath, laying crucial groundwork for the field. Subsequent studies expanded this foundation by demonstrating that robotic assistance produces greater and more rapid signal attenuation than manual techniques, and that combining robotics with general anaesthesia enhances catheter stability and lesion quality. His 2012 worldwide survey of the Hansen Robotic system further established the global clinical relevance of this technology. Kanagaratnam has also tackled complex cases, including robotic ablation in patients with congenital heart disease, illustrating the versatility of these systems. Collectively, his body of work has shaped how electrophysiologists approach precision-guided arrhythmia treatment worldwide.
