Echocardiographic Guidance and Assessment of Percutaneous Repair for Mitral Regurgitation With the Evalve MitraClip: Lessons Learned From EVEREST I

摘要: Objective Percutaneous mitral repair is rapidly developing as an alternative to cardiac surgery in select patients. The Evalve percutaneous E2E system uses the MitraClip replicate surgical suture-based approach. This procedure requires real-time echocardiographic guidance a unique and significant collaboration between echocardiographer interventionalist. transesophageal echocardiography (TEE) used primary imaging modality guide this essential its success. Methods In EVEREST I, US multicenter phase I safety feasibility trial, 47 patients with 3 or 4+ regurgitation (MR) were enrolled. trial involved standardized protocol anatomic-based vocabulary, predetermined standard TEE views, preprocedural strategy meetings, display of aids optimize communication procedural efficiency during placement clip. Results facilitated creation double-orifice valve all enrolled (100%), 40 discharged 1 more clips (85%). At discharge, successful clip ≤ 2+ MR was present 34 (74%). approach contributed reduction time perform over course at both initial new sites. Conclusions repair. A streamlined guidance, using common catheterization laboratory shortens allows for efficient
