MitraCut technique to prevent left ventricular outflow tract obstruction.
Figure 1
Figure 1
The MitraCut technique: the shortened large-bore sheath, together with the endoscopic scissor (A), were inserted over the guiding wire followed by the crossing of the mitral valve (B), alignment (C), stabilization (D), and final cutting of the A2 segment (E) (arrow). ∗Scissor tips.
