left ventricular outflow tract obstruction

Definitions
Left ventricular outflow tract (LVOT) obstruction can occur at the valvular, subvalvular, or supravalvular level. In general, there is an obstruction to forward flow which increases afterload, and if untreated, can result in hypertrophy, dilatation, and eventual failure of the left ventricle. [url:http://purl.obolibrary.org/obo/HP_0032092] Dynamic left ventricular outflow tract (LVOT) obstruction was thought to be a hallmark of hypertrophic obstructive cardiomyopathy, especially in those cases with isolated asymmetric septal hypertrophy and systolic anterior motion (SAM) of the mitral valve.[url:https://pubmed.ncbi.nlm.nih.gov/12356339/]
