Minimally Invasive Mitral Valve Surgery After Previous Cardiac Surgery

      Introduction: Reoperative mitral valve surgery by repeat sternotomy can be potentially high risk and challenging. Damage to the right ventricle or patent grafts and limited exposure of the mitral valve are potential complications upon sternal reentry. There are various techniques that can be used to perform minimally invasive mitral surgery in this patient population. Techniques described in the literature for myocardial protection include use of fibrillatory arrest, use of an endoaortic balloon, or use of the Chitwood clamp with antegrade cardioplegia. The purpose of this study was to examine the results of minimally invasive mitral valve surgery performed using a right minithoracotomy beating heart technique in patients who had previously undergone cardiac surgery.
