SpecialtyCardiology
CausesCongenital or acquired
TreatmentSurgery, medications, catheter based procedures (i.e. valvuloplasty)

A ventricular outflow tract obstruction is a heart condition in which either the right or left ventricular outflow tract is blocked or obstructed. These obstructions represent a spectrum of disorders. Majority of these cases are congenital, but some are acquired throughout life.[1]
