Previous studies suggested that stent area (SA) did not change after the Palmaz‐Schatz stent implantation. Whether these findings apply to other types of stent, however, is unknown. This study assessed vascular response to stent implantation using intravascular ultrasound (IVUS) studies. Serial (pre‐intervention to follow‐up) IVUS imagings were used to study 57 native coronary lesions after the GFX stent or the Multilink stent implantation. The vessel area (VA) at lesion site increased at follow‐up (16.92 ± 3.67 mm 2 after intervention to 18.17 ± 4.66 mm 2 at follow‐up, P < 0.01). The SA also increased from 8.39 ± 1.90 mm 2 after intervention to 8.80 ± 2.08 mm 2 at follow‐up ( P = 0.02). Thirty‐two percent of lesions showed late stent expansion. The stent expansion [Δ (after intervention to follow‐up) SA] correlated significantly with the VA growth [Δ (after intervention to follow‐up) VA] (r = 0.59, P < 0.0001). In conclusion, some lesions reveal late stent expansion after both the GFX stent and the Multilink stent implantation. Adaptive vessel remodeling may be followed by stent expansion. Cathet.
