To evaluate the successful revascularization in chronic total coronary occlusion lesions and to examine the relationship between lesion characteristics and procedural success and the frequency of in-hospital major adverse cardiac events after percutaneous coronary intervention in these patients.
All patients subjected to percutaneous coronary intervention from 2006 to 2008 were identified. These patients had unstable angina ranging from 2 weeks to more than 3 months duration, and majority was subjected to stent implantation.
A total of 110 consecutive patients were studied. They had been treated for chronic total coronary occlusion lesions during this period. There were 76 males and 34 females. Drug eluting stents (DES) were used in 84 patients whereas 26 received Bare metal stents (BMS). Successful revascularization was achieved in 103 lesions (94%). Only 6% patients showed unsuccessful results due to failure of the wire to cross the lesion. There was no recorded death during the procedure.
Due to latest guide wire technology, procedural techniques and operator experience, our study showed more than 90% success in percutaneous revascularization of chronic total coronary occlusion lesions, with an excellent survival rate .
评估慢性完全性冠状动脉闭塞病变经皮冠状动脉介入治疗的血管再通成功率，探讨病变特征与手术成功率之间的关系，以及这些患者住院期间主要不良心脏事件的发生频率。
确定2006年至2008年期间所有接受经皮冠状动脉介入治疗的患者。这些患者患有持续2周以上至3个月以上的不稳定型心绞痛，大多数患者接受了支架植入术。
共研究了110例连续患者。在此期间，他们接受了慢性完全性冠状动脉闭塞病变的治疗。其中男性76例，女性34例。84例患者使用了药物洗脱支架（DES），26例接受了裸金属支架（BMS）。103处病变（94%）实现了成功的血管再通。仅6%的患者因导丝未能穿过病变而手术失败。术中无死亡记录。
由于最新的导丝技术、手术技术和术者经验，我们的研究显示慢性完全性冠状动脉闭塞病变经皮血管再通成功率超过90%，生存率良好。
