While catheter ablation has been proven more effective at stopping atrial fibrillation than antiarrhythmic drugs, pulmonary veins may reconnect and atrial fibrillation may return, causing the catheter ablation to fail. At the recent Heart Rhythm Society meeting, Dr. Vivek Reddy, Director of Cardiac Arrhythmia Services at Mt. Sinai Hospital in New York City, presented clinical data on two catheters that could decrease reconnection. The TactiCath contact force sensing radiofrequency catheter and the CardioFocus Endoscopic Ablation System, a laser balloon catheter, could increase the durability of pulmonary vein isolation, thus decreasing ablation failures.
