Key result
Surgical treatment with septal myectomy significantly decreased left ventricular outflow tract gradient, velocity, septal thickness, and mitral regurgitation area at 1 year compared to baseline (P<.001).

Does surgical treatment improve echocardiographic parameters and symptoms in patients with HOCM and concomitant mitral valve abnormalities?
p-value: p=<.001
Septal myectomy with or without concomitant mitral valvuloplasty effectively relieves left ventricular outflow tract obstruction and mitral regurgitation in patients with HOCM and mitral valve abnormalities.
Song et al. (2018) conducted a cohort in Hypertrophic obstructive cardiomyopathy with concomitant mitral valve abnormalities (n=26). Surgical treatment (septal myectomy with or without concomitant mitral valvuloplasty) was evaluated on Left ventricular outflow tract gradient, left ventricular outflow tract velocity, septal thickness, and mitral regurgitation area (p=<.001). Surgical treatment with septal myectomy significantly decreased left ventricular outflow tract gradient, velocity, septal thickness, and mitral regurgitation area at 1 year compared to baseline (P<.001).
