Key result
Mitral valve reconstruction achieves ~95% success for severe degenerative MR in experienced centers.
Why the study?
The study was conducted to analyze the results of mitral valve reconstruction for degenerative mitral insufficiency considering etiological features.
Does mitral valve reconstruction improve outcomes compared to valve replacement in patients with severe degenerative mitral insufficiency?
Does mitral valve reconstruction improve outcomes compared to valve replacement in patients with severe degenerative mitral insufficiency?
Mitral valve reconstruction is the preferred treatment for severe degenerative mitral insufficiency, with high success rates in experienced centers, while transcatheter options like MitraClip offer alternatives for high-risk patients.
Supports reconstruction in experienced centers; leaves open randomized durability data versus replacement.
Mitral valve reconstruction is preferable for severe degenerative mitral insufficiency due to advantages over valve replacement regarding lifelong anticoagulation in patients with sinus rhythm, long-term survival and preservation of left ventricular function. The aim of the study was to analyze the results of mitral valve reconstruction for degenerative insufficiency considering etiological features. In centers with extensive experience, success rate is about 95%. Transcatheter technologies, in particular MitraClip, are becoming a good alternative to open surgery, especially for high risk patients. However, results of these surgeries are still far from ideal. Impeccable diagnosis and careful patient selection limit widespread use of this method.
