France Absorb • A French, observational, prospective, multicenter, controlled registry • From September 2014 to March 2016 • Systematic annual F/U during 5 years • Conducted by the French Interventional Working Group (G. A. C. I) • French Society of Cardiology (N. Naccache) • Statistical Analysis : V. Bataille • Sponsor : Abbott Vascular
End Points • Security data of BVS during 5 years as required by French Health Authorities • Primary end-point: in hospital and 1 year MACE • MACE have been adjudicated by an independent Event Committee (Pr Eltchaninoff, Pr Bauters, Dr Meyer)
LESIONS: P. S. P. RECOMMENDATION S Not too calcified No excessive tortuosity No left main No major bifurcation No restenosis strategy No bypass OCT, “ Stent Boost ” DAPT for 1 year

Conclusions • The main indication to implant a BVS in France is the YOUNG AGE • Procedural success is high and in-hospital and 1 year MACCE low • In-hospital and 1 year BVS thrombosis rate is reasonable • These good intermediate results in the real life are probably due to the respect of the BVS implantation rules and have to be confirm in the 4 years planned F/U.
