HIGH-RESOLUTION ANGIOSCOPY OF PROXIMAL CHRONIC TOTAL OCCLUSION MICROCHANNELS USING THE SCANNING FIBER ENDOSCOPE

Prior anatomic studies demonstrate frequent existence of patent microchannels in Chronic Total Occlusions (CTOs) but real-time visualization to guide Percutaneous Coronary Intervention is limited. The Scanning Fiber Endoscope (SFE) is a novel technology that provides images with significantly
