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.
