Expansion of Wiktor stents by oversizing versus high-pressure dilatation: A randomized, intracoronary ultrasound–controlled study
Two strategies to achieve optimal expansion of Wiktor stents in coronary arteries, oversizing at normal balloon pressures (group 1) and high-pressure dilatation (group 2), were compared. We randomly assigned 20 symptomatic patients with de novo coronary artery stenoses of

We randomly assigned 20 symptomatic patients with de novo coronary artery stenoses of <15 mm length to one of the two treatment groups. Intracoronary ultrasound catheter pull-backs after stent implantation showed incomplete stent attachment with one or two struts protruding into the vessel lumen in 3 of 10 patients in group 1 but in no patient after high-pressure dilatation in group 2 (
p < 0.01). Recross and high-pressure dilatation of the 3 stents in group 1 achieved complete attachment of all stents. Minimal luminal diameter was comparable between the groups (2.61 ± 0.34 mm in group 1 after stent delivery, and 2.68 ± 0.45 mm in group 2 after high-pressure dilatation). Minimal luminal area (expressed as a percentage of the reference cross-sectional area) was slightly but insignificantly greater in the high-pressure group (91.1% ± 25.6% vs 85.5% ± 15.1%). We conclude that implantation of Wiktor stents at normal inflation pressures does not reliably result in complete attachment of all struts to the vessel wall.
