Minimally invasive mitral valve repair

AbstractMinimally invasive mitral valve (MV) repair is being increasingly performed over the last 2 decades due to the constantly growing patient demand, since it offers a shorter recovery, less restriction and faster return to normal physical activities, reduction in pain, and superior cosmetic results. However, such procedures have to be performed through small incisions which limit visualization and the freedom of movement of the surgeon, in contrast to conventional operations that are performed through a sternotomy. Therefore, special long surgical instruments are required, and visualization is usually enhanced with advanced port-access two-dimensional (2D) or three-dimensional (3D) thoracoscopic cameras. This makes performance of a minimally invasive MV repair more challenging for the surgeon and is thereby associated with a steep learning curve. Nonetheless, the vast majority of patients who require MV repair are usually good candidates for this less invasive technique, though adequate patient selection is of utmost importance for success. Concomitant cardiac procedures such as ablation surgery for atrial fibrillation or right-sided interventions such as tricuspid valve surgery, heart tumor resection, and atrial septal defect closure can easily be performed using this approach. Short- and long-term results after minimally invasive MV repair are excellent and comparable with those achieved through a sternotomy approach. There are few drawbacks associated with minimally i...
