The Lead Episode 110: A Discussion of Left Bundle Branch Area Pacing in Hypertrophied Hearts: The Ex-Vivo Ovine Model to Study Deployment of Pacing Leads in Thick Septum LIVE from Heart Rhythm 2025 in San Diego-The Lead Episode 110 Speaker Information

The Lead Episode 110 Speaker Information

Pdf Summary

The discussion highlights the examination of left bundle branch area pacing in hypertrophied hearts using an ex vivo ovine model. This research is elaborated in the article published in the Heart Rhythm Journal, contributed by a team led by Darius Chapman and other experienced researchers. The session, hosted by Deep Chandh Raja from the Australian National University and Kauvery Hospital, delves into the challenges and methodologies associated with deploying pacing leads in thick septums, a common issue in hypertrophied hearts. <br /><br />The article proposes that utilizing an ovine model allows for the detailed study of myocardial mechanics and pacing lead deployment in a controlled environment, thus overcoming some of the challenges presented by the thick septum tissue in humans. This model may offer valuable insights into optimizing techniques and improving outcomes for patients with hypertrophic heart conditions who require pacing.<br /><br />Today's contributors include Parikshit S. Sharma from the Cleveland Clinic Florida, who has experience and connections with significant medical equipment firms such as Medtronic, Abbott, and Biotronik, despite having no direct conflicts of interest. The discussion emphasizes the importance of such studies in advancing cardiac pacing techniques, especially in cases where anatomical challenges hinder standard procedures.<br /><br />Through collaborative research and sharing of insights, this discussion fosters an understanding of how fat septum can affect pacing and guides the adaptation of new methods to ensure efficient treatment for patients with hypertrophied hearts. The meeting is a testament to the ongoing collaborative efforts within the medical community to enhance cardiac care and improve patient outcomes through rigorous scientific inquiry and innovation.
