A Prospective, Randomized Multicenter Trial of Cutting Balloon Before Stenting in Patients Undergoing PCI - REDUCE III
The goal of the trial was to compare the effect of cutting balloon vs plain balloon angioplasty (POBA) as a predilation strategy prior to stenting.
Patients Enrolled: 520
This is a Japanese prospective multicenter randomized study involving 520 patients in 38 centers. Angiographic follow-up was obtained in 87% of the patients.
There is no difference in complication or in-hospital MACE.
Cutting balloon vs POBA
TLR: 10.4% vs 14.9%
TVR 10.8% vs 15.3%
Restenosis 11.8% vs 19.1%, p=0.032
The strategy of predilation with cutting balloon appeared to reduce restenosis clinically as well as angiographically compared with plain balloon angioplasty. Prior studies have shown that cutting balloons redistribute plaque more than expanding the vessels, thus potentially inducing less injury to the vessel.
