Why the study?
Does the MitraClip system provide comparable results to repair surgery in patients with primary mitral regurgitation?
Does the MitraClip system provide comparable results to repair surgery in patients with primary mitral regurgitation?
MitraClip is a valid, less invasive alternative to surgery for high-risk patients with primary mitral regurgitation, offering fewer complications and improved quality of life despite lower durability.
May support MitraClip consideration in high-risk primary MR; leaves open durability versus surgery in randomized trials.
Mitral regurgitation (MR) is the most common valvular disease in industrialized countries, with a significant impact on patient quality of life and survival, especially in an increasingly elderly and comorbid population. Repair surgery is considered the treatment of choice for primary MR, offering excellent long-term outcomes. However, the MitraClip system, a less invasive percutaneous option based on the edge-to-edge principle, has proved to be a valid alternative for patients at high surgical risk, showing initial benefits in terms of fewer post-operative complications. Surgery remains superior in terms of durability and prevention of residual regurgitation, but the MitraClip system offers advantages in selected patients, with improvements in quality of life and reductions in hospitalizations for heart failure. A multidisciplinary approach and careful patient selection are essential to optimize outcomes.
