Coronary Artery Disease
Conditions
Brief summary
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).
Detailed 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.
Interventions
NSE (Goodman®) predilation + DCB (Sequent® Please) treatment
NC balloon predilation + DCB (Sequent® Please) treatment

Masking description
Outcomes assessor will remain blinded until the final study results are released.
Intervention model description
Patients will undergo 1:1 randomization to either non-slip element (NSE) predilation which will be the treatment group or non-compliant (NC) balloon predilation which will be the control group. The initiation of the trial is defined as the time of randomization. After study subjects' enrollment and randomization, the study intervention will take place immediately. The follow-up visits for the primary endpoint are scheduled at 1and 6 months after the index procedure.
