Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To evaluate the safety and effectiveness of paclitaxel-eluting coronary artery balloon dilation catheter (DIOR) in revascularization of coronary bifurcation lesions compared with paclitaxel-eluting balloon (Bingo), and to provide the clinical data for the formal application in China and for the approvement of China marketing.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a prospective, multicenter, randomize, control and non-inferior study. 220 patients with bifurcation lesions will be randomized 1:1 to each group. after the main branch has been treated successfully, and if the side branch's stenosis is more than 70% and can be pre-dilated by POBA (plain old balloon angioplasty) successfully, then randomizing. the patients in the study group will be treated with paclitaxel-eluting coronary artery balloon dilatation catheter (DIOR), while those in the control group will be treated with paclitaxel-eluting balloon (Bingo). Clinical follow-up will be conducted at baseline, operation, hospital discharge, 1 month, 6 months, 9 months and 12 months after operation, and angiographic follow-up will be conducted at 9 months. The primary endpoint is late lumen loss (LLL) in the balloon dilatation coverage area of side branch of at 9 month after operation. The secondary endpoints include device success, clinical success, target lesion failure (TLF), target lesion revascularization (TLR), clinical composite endpoints and imaging endpoints. The information of adverse events, serious adverse events and device defects will be collected during the study.

1. One or two bifurcation lesions, locate in different epicardial vessels, the bifurcation lesion in each epicardial vessel can not over 1; or 1 de nove coronary artery bifurcation can be included after 1 lesion of non-target vessel has been successfully treated by PCI (Percutaneous Coronary Intervention);
2. Residual diameter stenosis in main branch (MB) ≥ 70% (visually), or ≥ 50% simultaneously with clinical symptom, and the diameter stenosis in side branch (SB) ≥ 50% (visually); and the main branch's residual stenosis ≤ 20% with TIMI 3 flow post the stent placement, while the side branch diameter stenosis ≥ 70% post the MB stenting;
3. Fulfill the definition of truly bifurcation lesions by Medina type (1.1.1、1.0.1、0.1.1);
4. Diameter in side branch between ≥ 2.5 mm to ≤ 4.00 mm (visually) and lesion length ≤ 26 mm (visually);
5. Each side branch of the bifurcation lesion can be treated by only 1 study drug coated balloon (DCB) or control DCB, and the lesion shall be fully covered by the DCB ( the distal end of the balloon shall exceed the lesion at least 1 mm).

Exclusion Criteria

If subjects fulfill any of below criteria, this subject shall be exclude from this study.

5. Patients with renal insufficiency (estimated glomerular filtration rate \< 30ml/min/1.73m2 calculated by MRDR (Modification of Diet in Renal Disease) formula or subject is receiving renal dialysis)
6. Having a history of hemorrhagic diseases such as cerebral hemorrhage, gastrointestinal hemorrhage; stroke occurring or any situation occurring that may lead to prolongation of anticoagulation therapy within 6 months before operation;
7. History of coronary or peripheral vascular interventional therapy within 12 months before hospitalized.
8. Patients are allergic or contraindicate to contrast agent, paclitaxel, heparin, antiplatelet and anticoagulant drug;
9. The Subjects have other serious diseases and the expected survival is less than 12 months;
10. Investigators determine the subjects' compliance is poor, cannot complete the study as required;


1. Main branch lesion or non-target lesion(s) located in left main;
