Hypertrophic Cardiomyopathy: A Contemporary Look at Arrhythmic Risk and Treatment-Hypertrophic Cardiomyopathy: A Contemporary Look at Arrhythmic Risk and Treatment

Video Transcription

Video Summary

The session on hypertrophic cardiomyopathy (HCM) focused on arrhythmia risk and treatment, exercise management, and ICD indications. Dr. Michael Kim discussed atrial fibrillation (AF) ablation in HCM, highlighting the common issue of AF in HCM patients and the limited existing data on the efficacy of AF ablation. The procedure's success rates are lower in HCM compared to the general population, and many patients require multiple procedures. Dr. Asim Sharma addressed the complex issue of ventricular tachycardia (VT) ablation in HCM, emphasizing the challenges due to the thick myocardium and recommending pre-procedural imaging. Dr. Zakari explored antiarrhythmic management in HCM, recommending rhythm control and anticoagulation due to the high arrhythmic burden in these patients. Dr. Ethan Rowan discussed risk stratification and the importance of identifying major risk markers to guide ICD implantation. Newer risk markers include apical aneurysms and LV scar, which significantly contribute to arrhythmic risk. Dr. Rachel Lampert discussed the role of exercise, indicating its benefits and challenges in HCM management, highlighting that many HCM patients do not meet recommended exercise guidelines due to fear of sudden death. Recent guidelines now support mild to moderate exercise for HCM patients, with a cautious endorsement of competitive sports participation under certain conditions. In summary, HCM management is evolving, with a focus on understanding arrhythmic risk, promoting exercise with caution, and improving treatment strategies, including ablation and medication, tailored to individual patient profiles.
