Matched comparison of slotted tubular and coil stents: differences in acute gain, loss index, and clinical outcome.
Different stent designs may produce differences in immediate and long-term outcome. The objective of this study was to compare the immediate results and long-term outcomes of patients with lesions undergoing implantation of a single slotted tubular stent (Palmaz-Schatz) or a single coil stent (Gianturco-Roubin I). For this purpose, the authors studied patients matched for lesion length and vessel size. The consisted of 135 patients (141 lesions), and the Gianturco-Roubin group was composed of 50 patients (56 lesions). The coil stent was more often used for bailout indications. Larger immediate lumen gain was achieved with the slotted tubular stent. At follow-up examination, there was no difference in stent thrombosis; however, there was a trend toward lower angiographic restenosis and target-lesion revascularization in the Palmaz-Schatz group. Randomized trials using larger numbers of patients are needed to determine differences in outcome among different stent designs.
