Background: The bifurcation lesion is still associated with high restenosis rate particularly in the side branch ostium even in the era of drug-eluting stent. Kissing stent technique may be associated with better outcome in the bifurcation lesion. Methods: Thirty-two patients from 3 center were prospectively included in this prospective registry of kissing stenting with TAXUS stent (Boston, USA) in the bifurcation lesion. Inclusion criteria were type 1, 2 or 4 bifurcation lesion with reference vessel diameter 2.5 – 3.5 mm and lesion length  24 mm. ST-elevation myocardial infarction within 48 hour of onset and instent restenosis were excluded. Aspirin and clopidogrel were loaded before procedure and continued for 9 months. Results: The diagnosis of 9 patients were acute coronary syndrome. Eleven patients were diabetics. Left main bifurcations were 12 patients, left anterior descending artery 16 patients, left circumflex 3 patients and right coronary artery1 patient. Twenty eight cases were type 1 lesions (88%). Intravascular ultrasound was performed in 22 patients. Minimal luminal area after angioplasty was 6.81.4 mm2 in main and 6.82.7 mm2 in side branch. Creatine kinase-MB fraction level more than 3 times of normal value was noted in 3 patients. Subacute thrombosis developed in 2 patients during hospitalization, one of whom died. Conclusions: The kissing stent technique using TAXUS stent for the true bifurcation lesion was feasible and associated with large luminal gain in the side branch. The result of long-term follow-up will be presented.
