Yoshihisa Kinoshita：日本丰桥心脏中心副主任。介入心脏病学家，研究领域为冠状动脉疾病的新疗法和冠状动脉造影。
　　International Circulation: What do you think some of the most important developments are， in technology or technique， in CTO interventional therapy over the past year?
　　Dr. Kinoshita: Both technology and technique are very important. Recently， many new devices have become available and Japanese doctors are quite skilled in their use. However， technology has its limits and doctors can only reach a certain level based on the devices alone. In the end， it is technique and practice that are most important. For technology， in the CTO field， the development of new CTO wires is highly significant. Historically， the Japanese have led the field in guide wire development. About 20 years ago， there were few CTO guide wires， but now there are many and most of which are based on Japanese concepts. Having a good wire is essential， because if you cannot pass the guide wire in the lesion， you cannot perform the procedure. Wire development is still highly important.
　　《国际循环》：你认为在过去的几年中，CTO介入治疗的重要进展或技术有哪些？
　　Kinoshita教授：技术和操作技巧都非常重要。最近，有很多新型设备出现，日本医生精通于这些设备的应用。但是，技术上有一定局限性，基于技术本身，医生只能达到特定的水平。最终，操作技巧和临床实践是最重要的。对于CTO领域的技术来讲，新型CTO导丝的研发非常重要。从历史上来讲，日本人在导丝研发方面居于领先地位。大约20年前，CTO导丝的种类还很少，但现在CTO导丝有很多种类，大多数是基于日本人的概念。有好的导丝是至关重要的，因为如果导丝不能通过病变，就无法完成CTO的介入操作。目前，导丝研发仍然是相当重要的。
