The aim of this randomized trial is to compare the improvement in exercise capacity among patients with highly symptomatic hypertrophic obstructive cardiomyopathy despite optimal medical treatment who undergo alcohol septal ablation (ASA) or surgical septal myectomy (SSM).
This is a prospective, multicentre, open label, randomized controlled, non-inferiority trial (RCT) with a 1:1 randomization to alcohol septal ablation or surgical septal myectomy in patients with hypertrophic obstructive cardiomyopathy (HOCM) between 40-75 year of age with symptoms and/or syncope due to HOCM despite medical therapy. A total of 100 patients will be included. All patients will be evaluated with bicycle ergometry exercise test, MRI and 2D-echo before and 1 year after invasive treatment. Follow-up will be at 1,3 and 5 years.

| Quality of life evaluation using the The Kansas City Cardiomyopathy Questionnaire (KCCQ) | In the KCCQ, an overall summary score can be derived from the physical function, symptom (frequency and severity), social function and quality of life domains. For each domain, the validity, reproducibility, responsiveness and interpretability have been independently established. Scores are transformed to a range of 0-100, in which higher scores reflect better health status. For brevity, only the performance characteristics of the overall summary score are presented in this discussion. | Follow up will be 1,3 and 5 years |
