[Redo Coronary Artery Bypass Grafting].

Redo coronary artery bypass grafting( CABG) may be the most technically challenging operations in cardiac surgery. The coronary artery disease is more advanced, and the coronary targets may be suboptimal. Furthermore, the patients are typically older and sicker compared to those undergoing primary CABG. The frequency of redo CABG relative to total CABG procedures has been decreasing over time. Perioperative mortality for redo CABG is reported to be as high as three times that of primary CABG, but this risk is reduced with experience. Redo CABG is a complicated operation, and appropriate surgical strategies are essential for achieving good outcomes.
