Interventional cardiologists today are overwhelmed by a hugh array of new high technology investigatory devices at their disposal for the treatment of coronary arterial obstructive disease. These include the various atherectomy and laser devices, developed and introduced into clinical practice with the promise and intent of solving the limitations of conventional balloon angioplasty, namely those of acute closure and restenosis. But as more experience and data are obtained from the application of these devices, it is becoming clear that the latter have generally not been able to accomplish what they were intended to do. Although the immediate success rates have been uniformly high, acute closure has persisted and restenosis remains unabated. Nevertheless, some of these new devices have shown some fairly encouraging results in specific clinical circumstances. The targeted use of these instruments may prove to be a step in the right direction. This article reviews the current state of the art and the potential utility of certain of these devices.
如今，介入心脏病学家面临着大量新型高科技检查设备，可用于治疗冠状动脉阻塞性疾病。这些设备包括各种旋切术和激光设备，它们在研发并引入临床实践时，承诺并旨在解决传统球囊血管成形术的局限性，即急性闭塞和再狭窄问题。但随着从这些设备的应用中获得更多经验和数据，越来越明显的是，这些设备总体上未能实现其预期目标。尽管即时成功率一直很高，但急性闭塞问题依然存在，再狭窄也未见缓解。然而，其中一些新设备在特定临床情况下已显示出一些相当令人鼓舞的结果。这些仪器的针对性使用可能被证明是朝着正确方向迈出的一步。本文回顾了这些设备中某些设备的当前技术水平及其潜在用途。
