Treatment of Primary Coronary Artery Vascular Lesions With Biolimus Coated Coronary Balloon Dilation Catheter

Study Design:

• Prospective, international multi-center clinical study;
• It is planned to recruit 300 subjects in China and a total of 100 subjects in Indonesia and Thailand who meet the criteria for study inclusion to use at least one Biolimus coated coronary balloon dilation catheter (BioAscend) to treat primary in situ coronary artery vascular disease with a diameter of 2.0mm-2.75mm regardless of the number of blood vessels, the length and number of treated lesions;
• In the study, subgroups of long lesions, bifurcation lesions, and acute myocardial infarction were set up, and subjects who met the definition were directly entered into the subgroup analysis.
• Register and collect data using the EDC system;
• Enrollment method: competitive enrollment;
• Follow-up time points: postoperative to before discharge, 30 days, 6 months, 12 months, and 24 months.

Inclusion criteria

• Age ≥ 18 years;
• Primary coronary artery stenosis with a vessel diameter of 2.0 mm to 2.75 mm;
• Patients with residual stenosis of ≤ 30 percent after pretreatment and ≤ type B dissection; Patients who voluntarily participate in and sign the informed consent form, and who are willing to undergo follow-up as required by the protocol.

Exclusion criteria

• Pregnant or lactating females;
• Patients with cardiogenic shock;
• Patients with severe congestive heart failure or severe heart failure with NYHA class IV;
• Patients with severe valvular heart disease;
• Patients with a life expectancy of less than 24 months or factors that make clinical follow-up difficult;
• Patients who are considered unsuitable for inclusion by the investigator for other reasons.
