Coronary artery bypass grafting following in-stent restenosis of drug-eluting stents deployed in the left main coronary artery

Two cases of drug-eluting stent restenosis after percutaneous coronary intervention in the left main coronary artery and its bifurcation are presented. An off-pump coronary artery bypass grafting following in-stent restenosis was performed. Drug-eluting stents have shown a reduced frequency of in-stent restenosis and a good safety profile compared with bare metal stents. However, intervention with drug-eluting stents for left main coronary artery disease should be undertaken with care. It is also important to note that preoperative anti-platelet drug administration can increase the risk of major bleeding during and after emergent surgery.
