We compared the impact of low and high‐pressure balloon inflation on acute and late angiographic results of Multilink™ stent. Low‐pressure balloon inflation (9.5 ± 1.9 atm) was used in 43 stents and high pressure (17.1 ± 1.5 atm) in 44. A larger immediate luminal gain was achieved in stents with high‐pressure balloon inflation (1.80 ± 0.26 vs. 1.47 ± 0.62; P = 0.002), resulting in a larger mean diameter in this group (2.71 ± 0.37 vs. 2.48 ± 0.47; P = 0.017). At follow‐up, a larger luminal diameter was achieved in the high pressure group (1.93 ± 0.72 vs. 1.45 ± 0.66; P = 0.002) and a trend to a lower rate of angiographic restenosis (15% vs. 38%, P = 0.08).
