- Abstract
Introduction: The Hansen robotic system has only recently been used in the United States for catheter ablation procedures in humans. Atrial fibrillation (AF) ablation may be performed utilizing this system. We report our management of complications with early experience of this system. Methods and Results: All 71 patients in whom the system was utilized were included. In all patients, a 2-operator technique was to be employed; one operator manipulates the ablation catheter via the robot and the other manipulates the circular mapping and intracardiac echocardiogram catheters. There was no procedure-related mortality. All vascular complications occurred in the first 25 procedures performed. There were 6 intraoperative procedural-related complications. These included significant vascular complications (n = 4), one of whom required iliac vein stenting, and 2 cardiac tamponade (one related to a pop-phenomenon)—successfully treated by pericardiocentesis. Early complications (n = 3) were 1 tamponade several hours post-procedure, 1 vascular complication, and 1 pericarditis. Late complications included 5 patients with severe pulmonary vein stenosis (all in first 27 patients) and 1 patient with gastroparesis. All complications were successfully managed without persistent morbidity and occurred earlier in our experience. This led to specific alterations in our vascular access and ablation techniques. These include the use of a longer 14 Fr sheath, through which the robotic sheath is more safely advanced. The choice of ablation catheter and titration of power, particularly when the catheter has a perpendicular orientation to the atrial wall, is also important. Conclusions: The suggested modifications may make the system easier to use with the potential to reduce complications.
