From early experience in cardiac surgery on the mitral valve, access was gained in different ways: through left and right antero–lateral extended thoracotomy for closed and correspondingly for open mitral commissurotomy, from right parasternal access with rib resection, and via median sternotomy. Median sternotomy remains the most common approach for mitral valve procedures, such as replacement or repair, allowing good visualisation, exposure and working field. Applying the largely spread access as median sternotomy, surgeons always wanted to overcome the necessity of large incisions, get a better surgical view, to dissect with better respect to structural integrity and have better aesthetic results. Enhanced understanding of surgical bases and technological development sourced a breakthrough in minimally-invasive approach for mitral valve surgery, offering several advantages such as less postoperative pain, lower morbidity and mortality, faster recovery and shorter hospital stay. In an effort to share the institutional experience in less invasive surgery, this article demonstrates our approach in mitral valve repair through a right minithoracotomy in the 3rd or 4th intercostal space.
