Transcatheter Edge to Edge Mitral Valve Repair (MitraClip) Step by Step Guide

Abstract

Surgical mitral valve repair has been the gold standard treatment for severe degenerative mitral regurgitation. However, a segment of patient population is considered too high risk for surgery because of their age and/or comorbidities.Catheter-based interventions have been developed during the last decade to address mitral regurgitation in high surgical risk patients. MitraClip System (Abbott Vascular, Santa Clara, CA, USA) is FDA approved in high risk patients with primary or secondary mitral regurgitation who meet certain criteria. This article touches briefly on indications for transcatheter edge to edge mitral valve repair (TEER) and focuses on describing procedural steps to perform TEER usig MitraClip device. These steps include preoperative assessment and planning using TEE images, transseptal access to mitral valve, introducing transseptal sheath, steerable guide catheter (SGC), and clip delivery system (CDS), crossing the mitral valve, grasping the leaflets in desired location, and deployment. Procedural steps are also demonstrated in a brief video.
