Video Summary

The Heart Rhythm 2025 meeting, featuring experts like Pablo Neri and Jonathan Gordon, presented innovative studies and methods to advance cardiac care. Gordon’s study, focusing on radio frequency ablation and irrigation solutions, demonstrated that while half normal saline can deepen lesions in power-controlled catheters, it provides limited benefits compared to normal saline when used with temperature-controlled catheters. This highlights the nuanced effects of irrigation solutions on lesion creation.<br /><br />Jenny Connero discussed the hybrid epicardial and endocardial approach in treating persistent atrial fibrillation. The study showed promising two-year effectiveness in integrating surgical and catheter-based ablations, emphasizing improved success rates for patients with longstanding or previously failed ablation procedures.<br /><br />Merrick Hosman presented on sedation strategies during pulse-field ablation (PFA) procedures. The study compared traditional propofol boluses with continuous rememosilamine and ketamine regimens, concluding that the latter minimized adverse events significantly, suggesting safer sedation protocols for PFA.<br /><br />Monisha Krishnamurthy’s research on using unipolar voltage mapping post-PFA addressed lesion transmurality assessment, revealing it as a vital tool in guiding complete lesion sets. This method enhances ablation precision, potentially reducing AF recurrence.<br /><br />Lastly, Gordon Ho introduced an AI and CT-integrated workflow for VT and PVC ablation, demonstrating precise VT exit localization, which led to impressive ablation success rates. These advancements underscore the innovative intersections of AI, imaging, and cardiac procedures to improve patient outcomes in complex arrhythmias.
