[Restenosis estimation at the clinical level: methodologic and angiographic aspects].
Quantitative coronary angiography is the most objective and reproducible method for estimating restenosis after coronary angioplasty. Unfortunately, it does not strictly reflect the clinical restenosis. Numerous angiographic criteria have been defined, from the binary restenosis (>50% stenosis at the site dilated) routinely used by the clinician, to more sophisticated quantitative criteria in order to quantify the intimal hyperplasia, more objective but requiring rigorous criteria. However, new quantitative coronary analysis softwares have not been developed during the last years and each team had to evaluate its intra and inter observer variability. However, angiographic method is still the gold standard method for restenosis estimation, the ideal would be to defined an angiographic restenosis clinically consistent and well correlated with major cardiovascular events.
