First Attempt of Tip Detection-Antegrade Dissection and Re-Entry Using Conventional Intravascular Ultrasound in Coronary Intervention

Abstract

This study developed a tip detection (TD) method and chronic total occlusion (CTO)–specific short-tip intravascular ultrasound (IVUS) with a pullback transducer system. We devised TD–antegrade dissection reentry and standardized CTO wiring. This CTO-specific IVUS is not available outside Japan. This paper reports TD–antegrade dissection reentry performed using IVUS, widely used around the world.
