[Valve Surgery after Coronary Artery Bypass Grafting].

It has been reported that there are some risks of coronary artery graft injury while redo sternotomy was required for valve surgery after coronary artery bypass grafting (CABG). Also it is well known that clinical results after graft injury was poor. For avoiding graft injury, coronary artery graft must be placed away from the sternum at the time of initial CABG. For redo sternotomy, 3-dimensional-computed tomography can be useful. For aortic valve surgery after CABG, treatment of patent in-situ graft have to be discussed. For common practice, dissecting and clamping the patent in-situ graft during cardiac arrest were required. However, there are some reports showing good clinical results with moderate hypothermia, non-dissection and non-clamping graft. Furthermore, less mobidity rate results of transcatheter aortic valve implantation( TAVI) after CABG was reported. For mitral valve surgery after CABG, right mini-thoracotomy was reported as preferred procedure recently. Dissection area could be reduced than re-median sternotomy, although clamping aorta and patent graft were technically difficult. Two procedures were reported such as hypothermia and ventricular fibrillation or normothermia and beating heart. MitraClip procedure can be considered for high risk patients. Newly developed surgical and catheter technique may change the strategy for heart valve disease after CABG.
