Hypertrophic Cardiomyopathy (HCM) involves more than septal thickness. Dr. Nicholas Smedira, Surgical Director of Cleveland Clinic’s Hypertrophic Cardiomyopathy Center describes what happens when a patient has hypertrophic cardiomyopathy. A team approach is used to understand the anatomy and cause of obstruction. Many surgical approaches are available to individualize the care for the HCM patient to address the obstruction or treat the heart when a patient has HCM without obstruction.
