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
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
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]
- Aortic valve stenosis
- Supravalvar aortic stenosis
- Coarctation of the aorta
- Hypoplastic left heart syndrome
