Mid-term outcomes of biventricular obstruction and left ventricular outflow tract obstruction after surgery correction in child and adolescent patients with hypertrophic cardiomyopathy.

ABSTRACT:

Background

Data on the outcomes of hypertrophic cardiomyopathy (HCM) with biventricular obstruction are limited.

Objective

Our aim is to compare mid-term outcomes of biventricular outflow tract obstruction (BVOTO) HCM, left ventricular outflow tract obstruction (LVOTO) HCM and nonobstructive hypertrophic cardiomyopathy (NO-HCM) in children and adolescents who were treated with standard medication or surgical resection.

Methods

This retrospective study identified 21 BVOTO patients and recruited 27 LVOTO and 24 NO-HCM patients younger than 18 years presenting at our institution. The primary endpoint was all-cause death, and secondary endpoints were cardiovascular events.

Results

More BVOTO patients (61.9%) than LVOTO (19.2%) and NO-HCM patients (25%) exhibited Ne
