Minimally invasive mitral valve surgery (MIMVS) is revolutionizing the field of cardiothoracic surgery by offering patients less invasive alternatives to conventional sternotomy. This article reviews recent research and studies on the outcomes, challenges, and considerations surrounding MIMVS. Comparative studies reveal that while MIMVS offers advantages such as shorter hospital stays and reduced recovery times, it shows no significant differences in mortality or long-term quality-of-life outcomes compared to traditional methods. Techniques like mini-thoracotomy and artificial chordae have demonstrated safety and efficacy, although specific challenges such as higher rates of recurrent mitral regurgitation and the need for extensive postoperative monitoring persist. The learning curve for MIMVS emphasizes the importance of surgical expertise, with improved outcomes observed after mastering the procedure. Furthermore, complex degenerative mitral regurgitation presents unique challenges but can be effectively managed with tailored approaches. Patient selection, surgeon experience, and individualized treatment strategies are pivotal factors in achieving optimal results. While promising, the overall benefits of MIMVS require further exploration through large-scale randomized trials focusing on patient-reported outcomes and long-term success.
