Transcatheter Edge-to-Edge Mitral Valve Repair Using PASCAL System for a Patient With Medial Commissure Flail.

ABSTRACT:

Objectives

The aim of this report is to describe transcatheter edge-to-edge mitral valve repair using the PASCAL device in patients with medial commissure (MC) flail-induced primary mitral regurgitation.

Key steps

Perform a transseptal puncture above the MC. Insert the guide sheath (GS) into the left atrium (LA), guide the steerable catheter (SC) into the GS, and direct it toward the mitral valve. Withdraw the GS to the right atrium while maintaining the SC in the LA to approach the MC. Adjust the anterior-posterior trajectory using the GS flex knob. After leaflet grasping and PASCAL deployment, readvance the GS over the SC into the LA.

Potential pitfalls

Without a GS backup, the SC may become parallel to the aorta, hindering anterior leaflet visualization and complic
