Drug-coating Balloon Angioplasties for True Coronary Bifurcation Lesions (DCB-BIF)
Coronary Artery Disease
About this trial
This is an interventional treatment trial for Coronary Artery Disease
Eligibility Criteria
Inclusion Criteria:
- Subject must be age ≥18 years.
- Subject has silent ischemia, or stable/unstable angina, or acute MI older than 1-week from the onset of chest pain to admission.
- Subject (or legal guardian) understands the trial design and treatment procedures and provides written informal consent before any trial-specific tests or procedures are performed.
- Subject is willing to comply with all protocol-required follow-up evaluations.
- Target lesion must be a true bifurcation lesion on coronary angiography (defined as Medina 0,1,1, Medina 1,0,1, or Medina 1,1,1 coronary bifurcation lesions) and is eligible for percutaneous coronary intervention (PCI).
- Target lesion reference vessel diameter (both main vessel and side branch) ≥ 2.5 mm by visual estimation.
- Target lesion must have visually estimated stenosis ≥50%.
- Target lesion length of side branch must be <10 mm by visual estimation.
- Ostium side branch must have visually estimated stenosis ≥70% after stenting of the main vessel.
Exclusion Criteria:
- Patient with STEMI (within 1-week from the onset of chest pain to admission).
- Patient has known allergy to the study balloon/stent system or protocol-required concomitant medications.
- Patient is intolerable to dual anti-platelet therapy.
- Patient has any other serious medical illness that may reduce life expectancy to less than 12 months.
- Patient is pregnant or nursing.
- Patient is participating in another clinical trial that has not reached its primary endpoint within 24 months after the index procedure.
- Patient has a planned procedure that may cause non-compliance with the protocol or confound data interpretation.
- Restenotic lesion.
- Chronic total occlusion (CTO) lesion in either main vessel or side branch is not successfully recanalized.
- Severe calcification needing rotational atherectomy.

Active Comparator
PS-DCB
PS-NCB
For PS-DCB group NC balloon dilating ostial side branch (SB) (1:1 ratio). DCB dilating SB. Specifically, the DCB, which had to be 2-3 mm longer on each side than the predilatation balloon, was inflated at nominal pressure for 30~ 60 s. The ratio of the DCB diameter to the nominal diameter of the SB was recommended to be between 0.8 and 1.0. DCB should be delivered to the lesion within 2 min after entering human body. Kissing inflation using 2 noncomplian balloons. Stenting side branch with T and protrusion (TAP) technique if any of the following issues was observed after kissing balloon inflation: >type C dissection or thrombolysis in myocardial infarction (TIMI) flow <3. Final kissing inflation and proximal optimal technique (POT).
