Background  What happens to stent length when deployed in a coronary artery? It is the aim of this study.    Results  Consecutive 95 balloon-expandable stents (BES) were studied by intravascular ultrasound (IVUS) imaging. The stent length was measured from the longitudinal view in two ways: (1) edge-to-edge length (E-E) measured between distal and proximal stent frames located at one IVUS quadrant and (2) area-to-area length (A-A) measured between distal and proximal stent frames located at two or more IVUS quadrants. IVUS measurements were compared with the manufacturer-stated length (M-L). The median E-E length was significantly longer than M-L, 18.76 mm [interquartile range (IQR) 15.65–23.60] versus 18.00 mm (IQR 15.00–23.00), respectively,  p  < 0.0001. Also, the median A-A length was significantly longer, 18.36 mm (IQR 15.19–23.47),  p  < 0.0001, than M-L. Moreover, the E-E length was significantly different from A-A length,  p  < 0.0001. Among the stent groups, the differences were significantly present in all drug-eluting stent and bare metal stent (BMS) comparisons,  p  < 0.0001, except the A-A length versus M-L in BMS only. By multivariate analysis, the predictors of difference in stent length were as follows: lesion length,  p  = 0.01; pre-intervention minimal diameter of the external elastic membrane (EEM),  p  = 0.03; lesions present in the left anterior descending branch,  p  = 0.03; and M-L,  p  = 0.04.    Conclusions  In the present study, the length of BES measured by IVUS was significantly different from the manufacturer-stated length. In addition to the manufacturer length, other important factors such as lesion length, pre-intervention diameter of EEM, and affected vessel determine the stent length.
