Detailed Description

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

The prospective, multicenter, open-label, randomized clinical study is designed to verify the efficacy and safety of Wedge NC Scoring Balloon Dilatation Catheter in the application of dilatating coronary artery stenosis during PCI in comparison with a similar product on the market. The study is planned to enroll 198 subjects, who are randomly assigned to the test group (99 cases) and the control group (99 cases).

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Test Group

During PCI, percutaneous transluminal coronary angioplasty is performed on the target lesion using the Wedge NC Scoring Balloon Dilatation Catheter in the test group, subsequently completing the remaining procedure.

Group Type EXPERIMENTAL

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Age≥18 years old.
2. Subjects must have a single or double vessel coronary artery disease (CAD) and clinical evidence of ischemic heart disease, such as CAD, stable / unstable angina or silent ischemia.
3. Subjects with coronary artery stenosis confirmed by imaging examination are suitable for percutaneous coronary intervention (PCI).
4. Subject or a legally authorized representative must provide written informed consent prior to any study related procedures.
5. Subject must have de novo or restenotic lesion(s) in native coronary arteries, including in-stent restenosis suitable for percutaneous coronary intervention.
6. Target lesion with reference vessel diameter (RVD) of 2.0mm - 4.0mm, length ≤30mm (by visual inspection).
7. Only one lesion will be selected as the target lesion for revascularization when subjects have multiple lesions requiring treatment. Tandem lesions (defined as multiple lesions) are deemed one lesion if they can be covered by a single stent.
8. If target lesions and non-target lesions are treated simultaneously, they must be located in different coronary artery from the Target lesion

Exclusion Criteria

1. Subjects with bleeding tendency, contraindications to antiplatelet agent and anticoagulant therapy, and inability to anticoagulant therapy.
2. Subjects are sensitivity to contrast media which cannot be adequately pre-medicated.
3. Subjects with severe renal failure, whether on dialysis or not, with a glomerular filtration rate (eGFR) level \< 30ml/min/1.73m2 or serum creatinine level\> 2.0 mg/dl within 7 days prior to index procedure.
4. Subjects with decompensated congestive heart failure or cardiogenic shock.
5. Subjects with expected life less than 12 months.
6. Subjects with an active peptic ulcer or active gastrointestinal bleeding within 1 month prior to index procedure.
7. Subjects with an embolic stroke or transient ischemic attack within 2 months prior to index procedure.
8. Subject with known pregnancy or is nursing. Women of child-bearing potential shall undertake a pregnancy test before index procedure.
9. Subjects enrolled in any other clinical trial within 1 month prior to the trial or currently.
10. Subjects who have poor compliance and cannot complete the trial as required.
11. Lesions with total coronary artery occlusion (TIMI 0 or 1).
12. Severe calcifications (grade Ⅲ-Ⅳ) or extreme angulation (\>90°), etc., and lesions are inability to pass the study balloon or stent.
13. Lesions with visible thrombosis or ulcers.
14. Lesions with significant intima tears.
15. Unprotected left main disease.
16. Lesions located within an artery/saphenous vein graft or graft anastomosis.
17. Coronary artery spasm without significant stenosis.
18. Saphenous vein graft degenerative disease
19. Other situations that the investigator considers inappropriate for participation in this trial.
