简要总结
Over the past two decades, stents implantation has developed as a standard treatment for coronary stenosis lesions. However, int-stent restenosis (ISR) was one of the main factors affecting the long-term efficacy of coronary artery interventional therapy, with the incidence of ISR after percutaneous coronary intervention ranging from 5% to 35%. At present, there are three main means for ISR: (1) simple balloon dilation; 2) intravascular radiotherapy; and (3) drug elution stent. But the results are still not ideal. Drug coated balloon (DCB) is a new method that may be used to treat ISR in recent years. In the PEPCAD II study, when dealing with ISR, the paclitaxel eluting balloon (PEB) SeQuent® Please significantly reduced the major adverse cardiovascular events (MACEs) compared to the paclitaxel eluting stent (PES) TAXUS Liberte. In ISR-I and ISR-II trial, it was found that compared with uncoated PTCA balloons, PEB could significantly inhibit endothelial hyperplasia and significantly reduce MACEs treating ISR. The purpose of this study was to assess the efficacy and safety of a Chinese-developed PEB in treatment of coronary ISR compared to SeQuent® Please PEB.
