Safety and Efficacy of Spinous Balloon Dilatation Catheter in CAD Treatment
Study Details
Study Description
Brief Summary
The purpose of this study is to evaluate the safety and effectiveness of spinous process balloon dilation catheter (Plastic-Blade) in coronary vascular diseases, which is not inferior to the similar product on the market - coronary spinous process balloon dilation catheter (lacrosse NSE) produced by Goodman Co., Ltd..

Detailed Description
This study is a prospective, multicenter, randomized, controlled and non inferiority designed clinical trial. A total of 160 subjects with CAD from 8 centers will be randomized 1:1 to each group. All subjects evaluated the immediate lumen acquisition immediately after operation and the MACE of 30 ± 7 days after operation. The primary endpoint is the acquisition of lumen immediately after operation. The effectiveness of balloon was evaluated. The safety of balloon was evaluated by adverse events during operation.Clinical follow-up will be conducted at operation, discharge and 30 ± 7 days after operation. The target lesions included the following : opening lesions, bifurcation lesions, calcification lesions and fibrosis lesions; Diameter stenosis ≥ 70% (visual) with evidence of ischemia; Localized lesions with TIMI ≥ 1; RVD=2.00 and 4.00mm , and the vascular segment is suitable for balloon dilatation in anatomical structure。

Outcome Measures
Primary Outcome Measures
- Immediate lumen acquisition [during the procedure]
The difference of the minimum diameter of the target lesion before and after balloon dilatation in the test or control group measured by QCA.
Secondary Outcome Measures
- Rate of device success [during the procedure]
Proportion of patients who meet the success criteria. Success criteria be defined as the residual stenosis of the target lesion is less than 50% after balloon dilatation and the balloon delivery system is successfully withdrawn
- Rate of clinical success [from procedure to discharge ( to the 7th day after procedure)]
Based on device success, no patient occurred composite endpoint (PoCE) during hospitalization
- Incidence of related complications [30 days after balloon dilatation]
Including acute occlusion, vasospasm, vascular rupture, branch or collateral occlusion, subacute stent thrombosis, intimal tear, dissection, etc.
- % change of clinically meaningful laboratory tests [30 days after procedure]
Record the change of clinically meaningful laboratory tests
- Number of adverse events [30 days]
Adverse events occurred during balloon dilatation, after balloon dilatation to 30 ± 7 days after discharge
- Number of device related composite endpoint [30 days]
Including TLF, Cardiac Death, TV-MI and ID-TLR
- Number of patient oriented composite endpoint [30 days]
Including all cause death, MI, TLR, TVR, Revascularization of any coronary arteries and thrombus at the lesion.
- Total time of device operation performance [30 days]
Push capacity, passing capacity and withdrawal capacity
