Transcatheter Mitral Valve Edge-to-Edge Repair with the New MitraClip XTR System for Acute Mitral Regurgitation Caused by Papillary Muscle Rupture

摘要

Treatment of patients presenting with cardiogenic shock due to acute mitral regurgitation related to papillary muscle rupture poses significant challenges, owing to the high risk associated with conventional surgery. We hereby report successful transcatheter mitral valve edge-to-edge repair with the new Mitraclip XTR device (Abbott Vascular, Santa Clara, CA) in a patient with acute myocardial infarction and cardiogenic shock. Although surgical intervention remains the standard of care, the new MitraClip XTR system offers a novel treatment option for patients with papillary muscle rupture by overcoming the anatomic challenges often seen in this pathology.
