Ng ET AL.: Radiofrequency Wire & New Technique for the Treatment of Coronary Chronic Total Occlusion. Treatment of coronary CTO remains a technical challenge in contemporary PCI. The major limitation of the procedure is the inability to pass a guidewire across the CTO. A new OCR guidewire system has demonstrated clinical potential for navigating through CTO; in addition, the system is now coupled with RF energy for facilitating guidewire crossing through highly resistant hard total occlusive lesions. This device might offer new horizon for PCI to CTOs which would not have been attempted before. (J HK Coll Cardiol 2003;11:22-26)
