Intravascular ultrasound-guided retrograde dissection and reentry using a Conquest Pro 12 Sharpened Tip in a case of coronary chronic total occlusion

Abstract

The Conquest Pro 12 Sharpened Tip (CP12ST) is a novel guidewire used in intervention for coronary chronic total occlusion, with strong penetration force for hard plaques. Antegrade dissection and reentry techniques using the CP12ST have been reported, and their success and safety have been established. This report describes successful retrograde dissection and reentry using the CP12ST under intravascular ultrasound guidance in a situation in which reverse controlled antegrade and retrograde tracking was difficult to perform.
