Pediheart Podcast #337: Bundle Branch Block And The Fontan Patient

This week we review a study assessing the impact of bundle branch block (BBB) on exercise tolerance amongst the single ventricle Fontan patient cohort. Why would this be associated with worse outcomes for exercise? How should the cardiologist use this datum of BBB in a single ventricle patient to inform clinical decision making in this patient group? Why is cardiac resynchronization therapy so challenging in this patient group? Dr. Omar Meziab of The University of Arizona shares his deep insights this week. https://doi.org/10.1007/s00246-024-03500-1
