Brief Summary

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

This was a single-center, prospective, open-label, observational study. Patients with coronary artery disease confirmed by coronary angiography and treated with drug-coated balloon catheter alone for target vessels were enrolled in the Cardiology Department of our hospital in January 2022. The primary endpoint was late lumen loss within 12±3 months after surgery.

Study Groups

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

De novo coronary lesions: cutting balloon group

De novo coronary lesions were pretreated with a cutting balloon and then treated with a drug-coated balloon.

Pretreatment strategies before drug balloon therapy

Intervention Type PROCEDURE

Preconditioning strategies for the treatment of in de novo coronary lesions using drug-coated balloons.

De novo coronary lesions: non-cutting balloon group

De novo coronary lesions were pretreated with a non-cutting (Compliance balloon or/and non-compliant balloon) balloon and then treated with a drug-coated balloon.

Pretreatment strategies before drug balloon therapy

Intervention Type PROCEDURE

Preconditioning strategies for the treatment of in de novo coronary lesions using drug-coated balloons.

In-stent restenosis: Type-I

Body stenosis: restenosis of the stent body, not beyond the edge of the stent.The lesions were pretreated with balloon dilation and then treated with drug-coated balloons.

Different types of in-stent restenosis were treated with drug-coated balloons

Intervention Type PROCEDURE

A new classification method of ISR lesions was proposed to observe the clinical prognosis of different ISR lesions treated with drug-coated balloon.

In-stent restenosis: Type-II

Marginal stenosis type: restenosis at the edge of the stent, stenosis ≥50% within 5mm of the stent edge, which can continue into the stent.The lesions were pretreated with balloon dilation and then treated with drug-coated balloons.

Different types of in-stent restenosis were treated with drug-coated balloons

Intervention Type PROCEDURE

A new classification method of ISR lesions was proposed to observe the clinical prognosis of different ISR lesions treated with drug-coated balloon.

In-stent restenosis:Type-III

Diffuse proliferative type: the lesion extends to the whole scaffold body and beyond the edge of both ends.The lesions were pretreated with balloon dilation and then treated with drug-coated balloons.

Different types of in-stent restenosis were treated with drug-coated balloons

Intervention Type PROCEDURE

A new classification method of ISR lesions was proposed to observe the clinical prognosis of different ISR lesions treated with drug-coated balloon.

In-stent restenosis:Type-IV

Complete occlusion type: complete occlusion in the stent.The lesions were pretreated with balloon dilation and then treated with drug-coated balloons.

Different types of in-stent restenosis were treated with drug-coated balloons

Intervention Type PROCEDURE

A new classification method of ISR lesions was proposed to observe the clinical prognosis of different ISR lesions treated with drug-coated balloon.

4. Target lesions were treated with DCB for the first time.

Exclusion Criteria

1. Intraoperative implantation of salvage stent in DCB;
2. Acute myocardial infarction occurred within 1 week after DCB operation;
3. Less than 3 months of dual antiplatelet therapy after DCB operation, or more than 1 month of discontinuation of antiplatelet therapy;
4. The position of the stent could not be determined by coronary angiography.
5. Desmovascular disease or left main artery disease;
6. Atrial fibrillation;
7. Patients with severe heart failure, valvular heart disease, renal insufficiency, severe infection and autoimmune disease.
