The C-Sept Space: Another Step Forward in the Superiority of 3-Dimensional Echocardiography-Based Measurements

Systolic anterior motion of the mitral valve (SAM) first was described in the 1960s in patients with hypertrophic cardiomyopathy, and later following mitral valve (MV) annuloplasty, in the 1970s.1,2 Since then, it has been shown that left ventricular outflow tract obstruction (LVOTO) from SAM has a plethora of other predisposing risk factors. These risk factors include, but are not limited to, hypertrophic cardiomyopathy, anterior and medial displacement of the left ventricular papillary muscles, redundant MV leaflet tissue, and after mitral valve repair (MVR) and aortic valve replacement (AVR) surgeries.
