Hypertrophic Obstructive Cardiomyopathy

The Hearts in Rhythm Organization (HiRO) is a national network of Canadian researchers/clinicians, working towards a better understanding of the rare genetic causes of sudden cardiac death (SCD). The HiRO Hypertrophic Cardiomyopathy registry, biobank and imaging data repository (HiRO-HCM) is a multicenter study that will prospectively enroll patients with HCM as well as those carrying sarcomeric gene variants predisposing to HCM. The objectives of HiRO-HCM are: 1. to better understand the natural history of the disease and identify clinical markers and biomarkers for adverse outcomes; 2. to derive and validate risk prediction models for disease expression, complications and response to therapy; 3. to better define the genetic architecture of sarcomeric and non-sarcomeric HCM.

The primary purpose of this study is to evaluate the feasibility, the safety and the efficacy of the transapical beating-heart septal myectomy for the treatment of hypertrophic obstructive cardiomyopathy. This is a prospective, single-arm, single-center, first-in-man study.
