Efficacy and Safety of Sirolimus-Coated Spiral Balloon for Coronary Bifurcation Lesions

Recruiting now · Not applicable

Conditions studied: Coronary Bifurcation Lesion

In brief

This is a multicenter, prospective randomized controlled study to evaluate the safety and effectiveness of Sirolimus-coated spiral balloon (SuperFlow®) versus Paclitaxel-coated balloon (Bingo™) in the treatment of coronary bifurcation lesions.

Who can join

Age: 18 and older, up to 85. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Patients aged between 18 and 85 years, regardless of gender.
• Patients must voluntarily participate in the study and sign an informed consent form.
• Patients must demonstrate sufficient adherence to the study protocol and agree to follow-up visits at 1 month (±7 days), 6 months (±14 days), 9 months (±30 days), 12 months (±30 days), and 24 months (±30 days) post-procedure, with angiography required at 9 months (±30 days).
• Patients must have evidence of myocardial ischemia.
• Angiographically confirmed primary coronary bifurcation lesions (Medina classification non-0, 0, 1) with branch stenosis ≥70% (estimated visually).
• Patients suitable for PCI where the branch lesion is not expected to require stenting; stenting is planned for the main vessel, with DCB used on the branch. It is recommended to treat the branch with DCB first, followed by main vessel stenting.
• Residual stenosis ≤50% after pre-treatment of the branch lesion, TIMI 3 flow, with no dissection or only A or B grade dissection. C grade dissections should be carefully considered by the investigator before deciding, and are generally not included.
• The diameter of the branch vessel must be between 2.0 mm and 4.0 mm, with a lesion length ≤40 mm.

You may not qualify if…

• Patients with bleeding disorders or active gastrointestinal ulcers, those who have had a stroke within the past 6 months, or those who are expected to be intolerant to dual antiplatelet therapy post-intervention.
• Patients with severe renal insufficiency (creatinine level > 3.0 mg/dL or 265.2 µmol/L) and/or end-stage renal disease requiring dialysis.
• Patients in cardiogenic shock.
• Patients who have experienced a myocardial infarction within the week prior to enrollment.
• Patients with severe congestive heart failure or NYHA class IV severe heart failure.
• Patients with severe valvular heart disease.
• Patients who have undergone heart transplantation.
• Patients with a life expectancy of less than 1 year.
• Patients currently participating in other drug or device clinical trials that have not yet reached the primary endpoint.
• Patients with contraindications to taking aspirin and/or clopidogrel and/or ticagrelor.
• Patients known to be allergic to paclitaxel, rapamycin, contrast agents, etc.
• Pregnant or breastfeeding women, those with plans to conceive within the year, or those unwilling to use effective contraception.
• Target vessels that are completely occluded, severely calcified, have >45° angulation, or are non-protected left main lesions.
• Non-target lesions that cannot be treated prior to or fail to be treated successfully before addressing the target lesion.
• Target lesions in branch vessels that are in-stent restenosis.
• Other patients deemed unsuitable for inclusion by the investigator.
