氮氧化钛涂层支架在冠状动脉血运重建中的初步应用

目的 探讨氮氧化钛涂层(TTTAN2)支架在经桡/尺动脉途径行冠状动脉血运重建的临床效果.方法入选31例冠心病患者,均采用经桡动脉或尺动脉途径行冠状动脉血运重建.计算TTTAN2支架病变的通过率、早期支架内血栓发生率及随访MACE发生率.结果31例冠状动脉造影发现46处>75%狭窄病变,植入支架45枚,1枚支架未能通过病变,通过率97.8%.植入支架后无残余狭窄、支架脱栽、内膜撕裂、支架内早期血栓形成及冠状动脉破裂.随访1～5个月,无MACE发生.结论TTTAN2支架在冠状动脉血运重建方面临床应用效果良好.

Initial use of trans-ulner or trans-radial approach to coronary revascularization with titanium-nitride-oxide-coated stent

Objective To evaluate the efficacy of trans-ulner or trans-radial approach to coronary revaseularization with titanium-nitride-oxide-eoated stent (TITAN2). Methods 31 patients,who were planed to receive coronary revaseularization,were selected into this study. All patients with coronary revascularization were either by trans-ulner or by trans-radial approach. The pass-through rate of stent, early thrombosis in stent and MACE at followup were recorded for TITAN2. Results 46 lesions with stenosis > 75% with coronary angiograpby in 31 patients successfully underwent coronary revaseularization with TITAN2. One stent didn't go through the lesion in RCA. The pass-through rate of stent was 97.8%. Remaining stenesis ,stent unglues,endarterium laceration ,early thrombosis in stent and coronary rupture were not discovered after stent deployment. MACE was 0 at 1-5 month follow-up. Conclusion Confirmed good efficacy in coronary revascularization with TITAN2 is observed.
