冠状动脉内支架术治疗心肌桥

Intracoronary stenting in coronary myocardial bridge

目的 评价冠状动脉内支架术在治疗心肌桥中的可行性和疗效。方法 5例冠状动脉左前降支心肌桥施行冠状动脉内支架植入术。首例先用球囊行预扩张 ,然后在长段心肌桥病变处植入 2枚支架 ;另 4例未行球囊预扩张而直接植入各 1枚支架。结果 5例在支架植入后即刻行冠状动脉造影 ,结果显示 :有心肌桥在收缩期的挤压狭窄均消失 ,无明显残余狭窄。术后心绞痛症状均有明显缓解。术后随访 3～ 18个月 ,其间有 2例因出现胸闷症状分别在术后 1 5和 4个月行冠状动脉造影术 ,其中 1例为支架内再狭窄而再次行PTCA术。结论 冠状动脉内支架术治疗冠状动脉心肌桥是安全有效的 ,可以获得满意的造影结果和改善临床症状 ,但其远期疗效有待进一步更多病例的随访观察加以证实。

To evaluate the efficacy and feasibility of intracoronary stenting in coronary myocardial bridge (MD) Methods Intracoronary stenting was performed in five patients with MD Two Bestent stents were implanted into narrow site of MD in LAD after predilating in first case Then, we successfully implanted three Nir stents and one Jomed stent into lesions of LAD in other four patients Results All procedures were successful No major complications and death developed in five cases Coronary angiography showed that there was no residual stenosis after stenting Anginal symptoms were relieved or disappeared in all patients after stenting Conclusion Coronary stenting for MD is safe and effective Satisfactory angiographic result can be achieved
