Percutaneous coronary intervention （PCI） for CTO is technically challenging due to low procedural success ratesTM. Microcatheter is one of the important devices for treatment of CTOTM. It has been widely used attributed to the excellent crossability whenever angula- tion and tortuousity of the coronary artery is encoun- tered. In the process, the microcatheter has to be withdrawn from the guide wire after the wire is proved to locate in the true lumen.展开更多
