Background: Even in the era of drug-eluting stent, the result of coronary intervention for bifurcation lesion is still suboptimal. Kissing stent technique is the easiest technique among the two-stent techniques for bifurcation lesion.
Objectives: This study was performed to evaluate the safety and efficacy of kissing stent technique using TAXUS® stents in the bifurcation lesion.
Methods: This study was designed as a multicenter prospective registry including 4 centers in Korea. The inclusion criteria was type 1, 2, or 4 bifurcation, vessel size 2.5 – 3.5 mm, and expected proximal stent carina length less than 15 mm. The patients with cardiogenic shock, ST-elevation myocardial infarction within 2 weeks, thrombotic lesions, or instent restenosis were excluded. Clinical (30-day and 9-months) and 6-month angiographic follow-up was done.
Results: Total 50 lesion in 50 pateitns (male 42 patients, Age=61±10 years) were recruited. Stable angina was the most frequent diagnosis (74%) and diabetes was noted in 36% of the patients. Forty-four lesions (88%) were type 1 bifurcation. The most frequent lesion location was left anterior descending artery (48%), followed by left main stem (38%). The post-procedural peak CK-MB elevation more than 3 times of normal value was noted in 20% of patients. During 30-day period there were 1 death and 1 stent thrombosis, which was treated with re-intervention. Between 1- and 9-month period, 1 stent thrombosis and 5 target lesion revascularizations were noted. Pre- and post-procedural quantitative coronary angiography data was as following tables (RD=reference diameter, MLD=minimal luminal diameter). Nine-month coronary angiographic follow-up result will be presented.
Conclusion: Kissing stent technique is the simplest technique and is associated with reasonable long-term prognosis, if performed with proper technique.
