Propensity score matched comparison of isolated, elective aortic valve replacement with and without concomitant septal myectomy: is it worth it?

Background: Septal myectomy during open aortic valve replacement (AVR) is an effective surgical treatment for asymmetric secondary basal septal hypertrophy. Concerns regarding higher rates of complications associated with this procedure have been raised - such as permanent pacemaker implantation. The aim of this study was to compare outcomes and complications of patients with and without concomitant septal myectomy using propensity score matching applied to a large, consecutive single center cohort.
