Outcomes of Surgical Myectomy and Mitral Valve Repair for Hypertrophic Cardiomyopathy With vs Without Marked Septal Hypertrophy.

ABSTRACT:

Background

This study reports a single institution's clinical and echocardiographic outcomes for septal myectomy with vs without concomitant mitral valve interventions in patients with hypertrophic cardiomyopathy (HCM) and left ventricular outflow tract (LVOT) obstruction.

Methods

Consecutive patients who underwent transaortic septal myectomy with vs without subvalvular mitral apparatus intervention for HCM between October 2019 and March 2024 were included. All patients underwent transesophageal echocardiography and cardiac magnetic resonance imaging to confirm the pathology, measure intracavitary gradients, and assess mitral valve morphology. Patients were analyzed as an entire cohort and stratified by the presence of marked (> 15 mm) or only mild (≤ 15 mm) septal hypertrop
