Using Argentine forceps, the ‘LVOT flap’ is grasped and distracted inferiorly. Now a second 2.0 mm deep incision is made at the superior border of incisions 2 and 3. In the region of the sub-commissural area the two original incisions are rounded with subsequent incisions. The process is repeated eventually forming a flap in the LVOT resection is terminated by placing downward traction on the specimen and incising across the base.
