TEER non-inferior to mitral valve surgery with regard to death, HF rehospitalisation, stroke, reintervention of LVAD at one year.
Dr Volker Rudolph (Heart and Diabetes Center NRW, DE) and Prof Stephan Baldus (University Hospital of Köln, DE) joins us in London to discuss the MATTERHORN trial (NCT02371512; University Hospital of Köln).
This multicenter, randomized controlled trial evaluated mitral valve reconstruction strategies for patients with advanced functional or ischemic mitral regurgitation. A total of 210 participants with clinically significant, predominantly functional mitral regurgitation (MR), reduced left ventricular ejection fraction (LVEF ≥ 20%), and high surgical risk were enrolled. These patients experienced persistent heart failure symptoms despite optimal medical therapy. Participants were randomly assigned to either MitraClip therapy or surgical mitral valve repair. The primary outcome was a composite endpoint of death, heart failure rehospitalization, reintervention (repeat surgery or interventional procedure), device implantation, or stroke occurring within twelve months post-intervention.
Findings showed that TEER was non-inferior to mitral valve surgery, with a favourable safety profile of TEER as compared to surgery.
