ventricular outflow tract

ventricular outflow tract

In the heart, the pathway through which blood is normally ejected from the ventricle. For the left ventricle, it includes the walls of the ventricle, the anterior leaflet of the mitral valve, the aortic valve, the ascending aorta, and the arch of the aorta. For the right ventricle, it includes the walls of the ventricle, the pulmonic valve, the pulmonary trunk, and the pulmonary arteries.
