    Abstract:
    OBJECTIVE: To evaluate the clinical outcomes of treating bifurcation lesions with two drug-eluting stent (DES) techniques. METHODS: From October 2003 to February 2005, Seventy-one patients with 72 bifurcation lesions (the ostium of side branch > 2.5 mm in diameter) were treated by two DES. Forty-five of the bifurcation lesions were located in LAD/Diagonal (62.5%), 20 in distal left main coronary arteries (27.8%), 6 in LCX/OM (8.3%) and 1 distal RCA (1.4%). The Crush or modified Crush technique was used in 42, "T" technique in 19, modified "Y" technique in 5, "V" technique in 3 and Culotta technique in 3 bifurcation lesions, respectively. Fifty-nine Cypher or Cypher Select stents, 48 TAXUS stents, 25 Firebird stents and 24 bare metal stents were used for 144 lesions. Final kissing balloon inflation was performed in 60 bifurcation lesions (83.3%) after stenting procedure. RESULTS: Success rate of PCI procedure for the bifurcation lesions was 100%. One patient developed subacute stent thrombosis and underwent successful urgent revascularization. In-hospital major adverse cardiac events (MACE, death, AMI, revascularization) rate was 1.4% (1/71). Six months follow-up was made in 16 patients. No death and AMI occurred during the follow-up period in these patients. Total occlusion in ostium of the diagonal vessel was found in one patient with LAD/Diagonal bifurcation lesion 6 months post procedure. MACE rate during the follow-up was 6.3% (1/16). CONCLUSION: This study showed that the use of two DES techniques for the treatment of bifurcation lesions was safe and effective. The short-term outcome for this strategy was very satisfactory and primary data of 6-month follow-up also showed satisfactory results.
