Summary

The goal of this study is to investigate the equivalence in early and long-term efficacy between the two "Leave nothing behind strategies" (Drug-Coated Baloon \[DCB\] strategy with bail-out BioResorbable Scaffold \[BRS\] versus BRS strategy) of de-novo native coronary artery lesions in a relatively young Percutaneous Coronary Intervention (PCI) population, to be more specific, Patients with Chronic Coronary Syndromes (CCS) and Acute Coronary Syndrome (ACS) (Non-ST-segment Elevation Myocardial Infarction \[NSTEMI\] and Unstable angina) between 18-68 years of age scheduled for PCI. The main questions aim to answer are: DCB strategy with bail-out BRS implantation has equivalent clinical outcomes at 12 months compared to BRS strategy? DCB strategy with bail-out BRS implantation has noninferior angiographic in-segment net gain at 13 months compared to BRS strategy? DCB strategy with bail-out BRS implantation has equivalent clinical outcomes at 60 months compared to BRS strategy? Participants will be followed at: 1. st FU visit - 1 month (in hospital) 2. nd FU visit - 6 months (telephone) 3. rd FU visit - 365 days±15 days (telephone) - 1Y Primary efficacy endpoint 4. th FU visit - 395 days±15 days (in hospital) co-primary efficacy endpoint for the angiographic substudy 5. th FU visit - 730 days±30 days (telephone call) - 2Y 6. th FU visit - 1095 days±30 days (telephone call) - 3Y 7. th FU visit - 1460 days±30 days (telephone call) - 4Y 8. th FU visit- 1825 days±30 days (telephone call) - 5Y

Detailed description

The Leave Nothing Behind Study is an is an investigator-initiated trial. The Primary efficacy endpoint is target-vessel failure (TVF), defined as the composite of cardiovascular death, target-vessel myocardial infarction or ischemia-driven target-vessel revascularization (TVR) at 12 months. Co-primary efficacy endpoint (angiographic substudy) is the in-segment net gain at 13 months. Investigators aim to enroll 2256 patients in the main study and 196 patients in the angiographic substudy.

Conditions

• Drug Coated Balloon
• Bioresorbable Scaffold
• Percutaneous Coronary Intervention (PCI)
• Acute Coronary Syndrome (ACS)

Interventions

Type	Name	Description
PROCEDURE	Angioplasty with DCB (bail-out BRS)	Angioplasty starts with lesion preparation in both arms with a PTCA balloon catheter. The lesion is treated with the Mozec SEB through femoral or brachial artery. The DCB should be delivered to the target lesion within 120 seconds of insertion into the guide catheter. Under fluoroscopic visualization, the DCB is inflated at least 30 seconds (single inflation). If the results are insufficient, multiple inflation is permitted. If despite appropriate delivery and inflation of the DCB, the results remain insufficient bail-out BRS should be performed. Bail-out BRS is performed through femoral or brachial artery. After correct positioning, the BRS is deployed slowly, i.e. 10 seconds/atm up to 4 atm, then 5 seconds/atm up to nominal pressure or higher until desired expansion is obtained. After desired expansion obtained, pressure is maintained for 30 seconds before balloon deflation. After BRS implantation, Optical Coherence Tomography (OCT) is performed, if available.

After desired expansion obtained, pressure is maintained for 30 seconds before balloon deflation. After BRS implantation, OCT is performed, if available.
