About

This study is designed to investigate whether scoring balloon (non-slip element, NSE) predilation compared to non-compliant (NC) balloon predilation for de novo lesion in patients with high bleeding risk and planning to receive drug-coated balloon (DCB) treatment will lead to lower change in minimal lumen area (MLA) at 6 months by intravascular ultrasound (IVUS).

Full description

This is a pilot study that aim to enroll 60 subjects with high bleeding risk. All patients with coronary artery stenosis suitable for DCB treatment will undergo 1:1 randomization either to NSE predilation or NC balloon predilation using a randomization schedule. All subjects will be screened according to the predefined inclusion and exclusion criteria per protocol and will further undergo IVUS before DCB treatment. Data and images will be collected during the index procedure, and at the predefined 6-month IVUS follow-up visit.
