TCT-799 Direct Visualization of Pulmonary Vein Ablations within Reanimated Swine Hearts to Investigate Recent Advances in Cryo-balloon Technologies

The use of cryo-balloon ablation for pulmonary vein (PV) isolation has led to questions as to how best to optimize single procedure success. Specifically, what new indicators can be identified to better determine ideal ablation durations as well as the best catheter orientations and catheter
