Ventricular outflow tract

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

The right ventricular outflow tract is an infundibular extension of the ventricular cavity, which connects to the pulmonary artery. Causes of right ventricular outflow tract obstruction can be found here.

The left ventricular outflow tract connects the left ventricle to the aorta and is nearly indistinguishable from the rest of the left ventricle. Causes of left ventricular outflow tract obstruction can be found here.
