About

Mauricio Arruda is a leading cardiac electrophysiologist whose research has fundamentally advanced the safety and precision of catheter ablation for complex arrhythmias. His most impactful work centers on the biomechanics of ablation, specifically the relationship between catheter contact force and tissue damage. In his landmark 2008 study (163 citations), Arruda pioneered the use of robotic navigation to measure the exact grams of force applied to the endocardium during ablation, establishing critical thresholds that predict lesion formation, "popping," and char. This work directly informed safer ablation protocols, reducing the risk of perforation and thrombus. Beyond force dynamics, Arruda has explored innovative access strategies for challenging anatomies, as demonstrated in his 2020 case report on using internal jugular veins and robotic magnetic navigation for pulmonary vein isolation in a patient with left atrial isomerism and interrupted inferior vena cava. His contributions bridge engineering and clinical practice, providing electrophysiologists with quantitative tools to optimize lesion delivery. With a career dedicated to procedural innovation, Arruda remains a key figure in translating robotic and sensor technologies into tangible improvements in patient outcomes during atrial fibrillation ablation.
