Left Ventricular Outflow Tract Obstruction

2009
Left ventricular outflow tract obstruction (LVOTO) accounts for 5–10% of all congenital heart defects. LVOTO occurs at the valvar (70%), subvalvar (14%), and supravalvar (8%) level, and several levels of obstruction often coexist (8%) [1]. Another type of muscular subaortic stenosis, present with hypertrophic cardiomyopathy, is known as hypertrophic ...
