One-year data from an Italian multicentre randomised controlled trial of the IN.PACT Falcon drug-eluting balloon from Medtronic have demonstrated positive and durable clinical results with the novel angioplasty device in the treatment of stenotic de novo lesions in small coronary arteries, according to a presentation made at EuroPCR 2013 in Paris, France (21–24 May).
The new data came from the BELLO (Balloon elution and late loss optimisation) study, which enrolled 182 patients across 15 hospitals in Italy to evaluate the safety and effectiveness of two medical devices: Medtronic’s IN.PACT Falcon drug-eluting balloon and the Taxus drug-eluting stent from Boston Scientific.
According to the results, nearly two-thirds (64.9%) of the vessels treated in the BELLO study with the drug-eluting balloon were smaller than 2.25mm in diameter, for which no drug-eluting stent is currently available.
The previously presented six-month angiographic outcomes of the BELLO study favoured patients treated with the drug-eluting balloon. The study met its primary endpoint, late lumen loss at six months, with statistical significance showing superiority of the drug-eluting balloon over the drug-eluting stent (0.08mm vs. 0.29mm, p=0.001).
Building on these data, the latest results from the BELLO study have demonstrated favourable outcomes for the IN.PACT Falcon drug-eluting balloon. At one year, the clinical outcomes of major adverse cardiac events (MACE), myocardial infarction and target lesion revascularisation were statistically similar for both devices:
- MACE—drug-eluting balloon, 10.0%; drug-eluting stent, 18.5% (p=0.31)
- Myocardial infarction—drug-eluting balloon, 1.1%; drug-eluting stent, 5.5% (p=0.10)
- Target lesion revascularisation—drug-eluting balloon, 4.4%, drug-eluting stent, 9.8% (p=0.25)
“The BELLO study shows that treating de novo coronary lesions with the IN.PACT Falcon drug-eluting balloon is a viable option, with strong clinical outcomes to one year,” said the presenter of the new data, Azeem Latib of San Raffaele Hospital and EMO-GVM Centro Cuore Columbus in Milan, Italy. “The one-year results suggest that this novel angioplasty device should not necessarily be limited to only treating in-stent restenosis in coronary arteries. They also suggest that lesions in relatively small coronary arteries are possibly a strong application for this particular device.”
The Medtronic IN.PACT Falcon drug-eluting balloon received CE mark in 2009 and is available in many countries around the world. It is not commercially available in the USA.
