Orbital atherectomy versus standard balloon strategy for calcified coronary bifurcation lesions
Official title: Randomized Trial of Orbital Atherectomy Versus Standard Strategy in Calcified Bifurcation Lesions
Run by Fundación EPIC · NCT06736899 · Data updated 2026-11-12
This study tests whether using orbital atherectomy before stenting helps adults with moderately or severely calcified coronary bifurcation lesions get better stent results than the standard balloon-first approach.

Is this trial a fit for you?
✓Likely a good fit
Adults aged 18 or older with moderately or severely calcified coronary bifurcation lesions (side branch ≥2 mm) who are candidates for PCI with stent implantation and can commit to one-year follow-up are ideal candidates.
✕Probably not a fit
Patients with contraindications to orbital atherectomy—such as thrombotic lesions, vascular graft disease, recent revascularization within nine months, cardiogenic shock, severe left ventricular dysfunction, allergy to required device components, or life expectancy under one year—are unlikely to benefit from enrollment.

What this trial studies
This is a multicenter, open-label, prospective randomized study comparing initial plaque modification with orbital atherectomy plus stent implantation versus conventional balloon angioplasty plus stent implantation for calcified coronary bifurcation lesions. Patients with moderately or severely calcified bifurcation lesions (side branch ≥2 mm) are randomized to one of the two strategies and followed with angiography and optical coherence tomography (OCT) to document stent expansion, apposition, and related outcomes. The trial collects safety and efficacy outcomes, including imaging endpoints and clinical events, with planned clinical follow-up out to one year. The goal is to determine whether orbital atherectomy facilitates provisional stenting and reduces complications related to underexpanded or malapposed stents.
Why it matters
Potential benefit: If successful, the approach could improve stent expansion and reduce restenosis or stent thrombosis in calcified bifurcation lesions.
How similar studies have gone: Atherectomy devices have shown promise for improving stent expansion in heavily calcified coronary lesions, but randomized data specifically focused on calcified bifurcation lesions are limited, making this a relatively novel, targeted comparison.
