Left ventricular outflow tract

Last revised by Craig Hacking on 31 Jan 2024

The left ventricular outflow tract (LVOT) (also sometimes called the aortic vestibule) is considered to represent the region of the left ventricle that lies between the anterior cusp of the mitral valve and the ventricular septum. It directs blood towards the aortic annulus and through the aortic valve during systole. Its dimensions are often recorded in TAVI workup studies.
