FFR et MB avant ATL SB MB ?
The Value of FFR in terms of Clinical Outcome Has Been Validated in patients with • Intermediate stenoses(Pijls et al. New Engl J Med 1996) • (Pijls et al. JACC 2010) • Post-myocardial setting (De Bruyne et al Circulation 2001) • (Ntalianis et al. JACCInterv 2010) • Multivessel Disease (Tonino et al. New Engl J Med 2009) • Left main stenosis(Hamilos, Muller et al. Circulation 2009) • Proximal LAD stenosis(Muller et al. JACCInterv 2011)

Lateral Inhibition (or Mach band visual effect) "Mach bands are an optical illusion consisting of an image of two wide bands, one light and one dark, separated by a narrow strip with a light-to-dark gradient. The human eye perceives two narrow bands of different brightnesses either side of the gradient that are not present in the original image." http://en.wikipedia.org/wiki/Lateral_inhibition
FFR et SB avant ATL 1. FFR overestimates the severity Jailing of a pressure wirebetween the stent and the vesselwallis not recommended 2. Anatomical changes after MB stenting: carina shift, stent struts 3.

FFR et SB après ATL FFR-guided provisional SB intervention strategy is feasible and effective 2. Functionalstatus of jailed SB lesionsafter DES implantation does not change significantlyduringfollow-up Koo, EuropeanHeart Journal (2008)
Anatomically significant stenosis is frequently functionally insignificant • Among side branch lesions > 75% stenosis after main vessel stenting, only 27% were functionally significant. FFR P d = P a (Pd/Pa) Koo BK, J Am CollCardiol 2005
