A ventricular outflow tract obstruction is one type of congenital heart defect in which either the right or left ventricular outflow tract is blocked or obstructed. These obstructions represent a spectrum of disorders.

Right side[edit]

A right ventricular outflow tract obstruction (RVOTO) may be due to a defect in the pulmonic valve, the supravalvar region, the infundibulum, or the pulmonary artery.[1]

Left side[edit]

A left ventricular outflow tract obstruction (LVOTO) may be due to a defect in the aortic valve, or a defect located at the subvalvar or supravalvar level.[2]
