Echocardiogram: LVOT Obstruction After MVR

Following a Carpentier Edwards mitral valve replacement (MVR), left ventricular outflow tract obstruction is observed that leads to a gradient of more than 50mm Hg. This rare complication occurs in 4–5% of patients after MVR. Major anatomic factors that may predispose a patient to obstruction following MVR include degenerative mitral valve insufficiency with excess leaflet tissue, non-dilated left ventricular cavity, and narrow mitro-aortic angle.
