Abstract: Objective: Optimal stent expansion during PCI is critical in detecting immediate and long term outcome. Quantitative coronary angiography enhances the current practice to assess coronary lesion rather than visual estimation. In this study we attempt to analyze the routine Pre and post stenting QCA with multilevel parameters including longitudinal and luminal (radial) diameter for all the cases undergoing Percutaneous coronary intervention with drug eluting stent. The aims of QCA measurement is to select appropriate stent size, to decide necessity of preand post dilatation, to determine the adequacy stent deployment and to evaluate the Prevalence of stent under expansion during routine PCI.
