Left Ventricular Outflow Obstruction

Left ventricular outflow tract (LVOT) obstruction is a condition that restricts blood flow from the left ventricle of the heart.  LVOT obstruction is defined as a peak gradient of at least 30 mm Hg at rest or with provocation. A peak gradient of at least 50 mm Hg is usually the threshold for surgical or percutaneous intervention. Dr. Nicholas Smedira specializes in the surgical management of LVOT obstruction and discusses considerations for assessment and intervention.
