Patients with obstructive hypertrophic cardiomyopathy (oHCM) frequently present with heart failure symptoms refractory to medical therapy and require septal myectomy (SM). The magnitude of benefit from SM is thought to be better than the recently reported data from EXPLORER-HCM and REDWOOD-HCM trials. We prospectively investigated the association between SM, patient-reported 12-item Kansas City Cardiomyopathy Questionnaire (KCCQ-12) and physician-reported NYHA class in a community-based cohort of oHCM. SM ± submitral valve repair is associated with improvement in NYHA class and KCCQ-12 but with a varying magnitude of benefit.
