Implication
Supports feasibility in small series; leaves open efficacy versus controls in randomized trials.
Structured PICO
Is endovascular beta-radiation safe and feasible for reducing restenosis after coronary balloon angioplasty in patients with coronary artery disease?
P
Population
23 patients with coronary artery disease undergoing successful balloon angioplasty of stenoses of native coronary vessels.
I
Intervention
Endovascular beta-radiation (12, 14, or 16 Gy at 2 mm) using encapsulated 90Sr/Y sources delivered after balloon angioplasty.
O
Outcome
Feasibility of delivery, in-hospital or 30-day morbidity or mortality, and angiographic restenosis (late loss, late loss index, restenosis rate).surrogate
Endovascular beta-radiation after coronary balloon angioplasty is safe, feasible, and associated with low rates of late lumen loss and restenosis.
