Key result
Transaortic myectomy with concomitant procedures for HOCM yielded strong long-term outcomes, with 10-year survival of 80% compared to 87% for isolated myectomy, and early lethality of 2.0% vs 1.3%.
Why the study?
Does transaortic myectomy with concomitant procedures yield comparable short and long-term outcomes to isolated myectomy in patients with HOCM?

Concomitant procedures during HOCM myectomy show acceptable survival; leaves open randomized confirmation of equivalence to isolated cases.

Does transaortic myectomy with concomitant procedures yield comparable short and long-term outcomes to isolated myectomy in patients with HOCM?
Absolute Event Rate: 80% vs 87%
Surgical treatment of HOCM with transaortic myectomy provides excellent long-term results, even when concomitant cardiac procedures are required.
Minami et al. (2002) conducted a cohort in Hypertrophic obstructive cardiomyopathy (HOCM) (n=125). Transaortic myectomy with concomitant cardiac procedures vs. Isolated transaortic myectomy was evaluated on Survival rates after 10 years. Transaortic myectomy with concomitant procedures for HOCM yielded strong long-term outcomes, with 10-year survival of 80% compared to 87% for isolated myectomy, and early lethality of 2.0% vs 1.3%.
