✦ Synopsis
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%,
