Fate of the Left Ventricular Outflow Tract After Rastelli With Selective Infundibular Muscle Resection.

Background: The Rastelli procedure has been criticized for a high rate of left ventricular outflow tract obstruction (LVOTO) and translocation procedures have been proposed as an alternative. Infundibular resection can be performed during Rastelli to optimize the outflow tract. This study examines whether a selective policy to enlarge the outflow tract improves Rastelli outcomes across all morphological variants.
