ClinConnect Summary

The DEBSIDE clinical trial is a prospective, non-randomized, multicenter, interventional study evaluating the investigational Danubio Paclitaxel Eluting Coronary Balloon for the treatment of Side Branches (SB) of de novo bifurcation lesions with a side branch reference vessel diameter ≥2.0 mm and ≤3.0 mm. During the procedure, a dedicated drug-eluting bifurcated stent will be implanted in the main branch. The trial will allow the treatment of lesion of all Medina type except (0,0,1) in native coronary arteries with sequential predilatation of the main and side branch.

Eligibility criteria

• Inclusion Criteria:
• • 1. De novo bifurcation lesions following the Medina classification except (0,0,1).
• • 2. Reference diameter main branch \>= 2.5 and ≤ 3.5 mm and side branch \>= 2.0 and ≤ 3.0 mm.
• • 3. Main branch lesion length ≤ 26mm and side branch lesion ≤ 6mm.
• • For a 24mm stent in the main branch: main branch lesion length ≤ 14mm proximal and ≤ 12mm distal to the carina.
• • For a 18mm stent in the main branch: main branch lesion length ≤ 8mm proximal and ≤ 12mm distal to the carina.
• • Indeed an additional stent (Amazonia PAX 8mm) can be overlapped distally with the Nile PAX if a target lesion segment ≤4mm remains uncovered after implantation of the bifurcated stent.
• • 4. Maximum two bifurcation lesions per patient on two different vessels with at least one lesion treated with the procedure described on the protocol (involving the Danubio).

• • 11. The patient is an acceptable candidate for percutaneous transluminal coronary angioplasty (PTCA), stenting, and emergent coronary artery bypass graft (CABG) surgery.
• • 12. The patient or patient's legal representative has been informed of the nature of the trial and agrees to its provisions and has provided written informed consent as approved by the Ethics Committee (EC).
