Abstract:
Objective To evaluate the angiographic effectiveness of stenting for non-protected left main coronary leisions. Methods The follow-up angiograms of 18 patients who had received stent implantation for non-protected left main disease during 1997-2004 were assessed. Results (1) There were totally 9 patients implanted with two stents in distal left main bifurcation lesion. Among the 6 patients who had implanted two drug eluting stents using V technique, 4 of them had ostial restenosis of the branches and had TLR. Another 2 patients with bare metal stents implanted using T-stest technique also experienced restenosis and had TLR. (2) In the 9 patients with single stent implanted, 5 patients implanted the stents crossing-over the LCX and only 1 of them had restenosis. Among the 3 patients who had received left main body stenting, one patient had diffuse restenosis and performed TLR. Conclusion (1) Implantation of 2 stents in distal left main lesion showed a high restenosis rate. On the other hand, crossing over the LCX can be applied safely in left main bifurcation lesions and show a better prognosis.
