Key result
Combined anterior mitral leaflet retention plasty and septal myectomy resulted in 0 mortality and no systolic anterior motion over a mean 11.85-year follow-up.
Why the study?
Does combined anterior mitral leaflet retention plasty and septal myectomy reduce left ventricular outflow tract obstruction and prevent systolic anterior motion in children with hypertrophic obstructive cardiomyopathy?

May support combined ALRP plus myectomy for durable relief in select pediatric HOCM; extends single-center cohorts but leaves randomized confirmation open.

Does combined anterior mitral leaflet retention plasty and septal myectomy reduce left ventricular outflow tract obstruction and prevent systolic anterior motion in children with hypertrophic obstructive cardiomyopathy?
Combined anterior mitral leaflet retention plasty and septal myectomy provides sustained relief of outflow tract obstruction and prevents systolic anterior motion in children with hypertrophic obstructive cardiomyopathy.
Walter et al. (2009) conducted an observational in Hypertrophic obstructive cardiomyopathy (n=12). Combined anterior mitral leaflet retention plasty and septal myectomy was evaluated on Left ventricular outflow tract pressure gradient, systolic anterior motion, and mitral regurgitation. Combined anterior mitral leaflet retention plasty and septal myectomy resulted in 0 mortality and no systolic anterior motion over a mean 11.85-year follow-up.
