In this episode, Professor Yong-Joon Lee discusses a significant study on the one-year clinical outcomes of left atrial appendage occlusion (LAAO) using the Watchman device in older patients with non-valvular atrial fibrillation. The findings highlight the procedure's safety and efficacy, revealing that combined LAAO and ablation significantly reduce the risk of thromboembolic events, while also addressing gaps between clinical guidelines and real-world practices.
