A ventricular outflow tract is a portion of either the left ventricle or right ventricle of the heart through which blood passes in order to enter the great arteries.

The right ventricular outflow tract (RVOT) is an infundibular extension of the ventricular cavity which connects to the pulmonary artery. The left ventricular outflow tract (LVOT), which connects to the aorta, is nearly indistinguishable from the rest of the ventricle. The outflow tract is derived from the secondary heart field, during cardiogenesis.
