Spatial relationship between mitral valve and ventricular septum assessed by resting echocardiography to diagnose left ventricular outflow tract obstruction in hypertrophic cardiomyopathy.

ABSTRACT:

Aims

Echocardiographic diagnosis of left ventricular outflow tract obstruction (LVOTO) in hypertrophic cardiomyopathy (HCM) often requires extensive provocative manoeuvers. We investigated, whether echocardiography-derived parameters obtained at rest can aid to determine the presence of LVOTO in persons with HCM.

Methods and results

Consecutive patients with HCM admitted to a referral centre underwent standardized transthoracic echocardiographic examination including provocative manoeuvers. Under resting conditions, the length of mitral leaflets and distances between mitral valve coordinates and ventricular walls were blindly measured in parasternal long axis (PLAX) and apical three-chamber (3ch) views, both at early and late systole. Among 142 patients (mean age 59 ± 13 yea
