INTRODUCTION Popping, char and perforation are complications that can occur following catheter ablation. We measured the amount of grams (g) applied to the endocardium during ablation using a sensor incorporated in the long sheath of a robotic system. We evaluated the relationship between lesion formation, pressure, and the development of complications. METHODS Using a robotic navigation system, lesions were placed in the left atrium (LA) at six settings, using a constant duration (40 seconds… CONTINUE READING
