Dr. Thomas McGinn and cardiac electrophysiology expert Dr. Arash Aryana focus on afib and the use of ablation, including a new randomized controlled trial that compares the success of Pulmonary Vein Isolation (PVI) against PVI plus Posterior Wall Isolation (PWI) using the posterior "Box" isolation approach. Dr. McGinn and Dr. Aryana discuss: 

• PVI vs. PVI + PWI and whether there is a significant difference in results
• Whether the data supports posterior “box” isolation as a preferred strategy
• A comparison of "box" vs. "direct" posterior wall ablation methods
