Intravascular Ultrasound Versus Angiography Guided Drug-coated Balloon

This is a prospective, multicenter, randomized controlled trial that aims to enroll 260 patients with high bleeding risk. All patients with coronary denovo lesions suitable for DCB treatment will undergo 1:1 randomization to either IVUS guidance or Angiography guidance using the Central Randomization System. All subjects will be screened according to the predefined inclusion and exclusion criteria per protocol. Data and images will be collected during the index procedure, and at the predefined 7-month coronary angiography follow-up visit.
