Figure 1 Estimates for a Theoretical Surgical Myectomy Versus ASA Trial

Flow diagrams comparing patient selection and recruitment in the BARI study (coronary artery bypass graft surgery [CABG] vs. percutaneous transluminal coronary angioplasty [PTCA]): a representative example of a coronary artery disease-related randomized trial (23) (left) and a hypothetical myectomy versus alcohol septal ablation (ASA) trial (right). HCM = hypertrophic cardiomyopathy.
