abstract

  • One hundred and thirty-four consecutive patients undergoing elective coronary stenting were studied to assess the relative performance of Palmaz-Schatz (PS), Gianturco-Roubin (GR), and Wiktor (W) stents. Eighty-six percent of patients underwent follow-up angiography. Initial and follow-up angiograms were assessed by a central angiographic core laboratory. Attempts were made to place 81 Palmaz-Schatz (PS) stents, 21 Gianturco-Roubin (GR), and 32 Wiktor (W) stents. PS stents were less frequently successfully deployed (88% PS vs. 100% GR vs. 97% W; P = 0.03). The final percent stenosis was greater with the GR stent (32% GR vs. 14% PS vs. 19% W; P < 0.001). The restenosis rate was lower in the PS group (PS 48.2% vs. GR 66.7% and W 68.4%; P = 0.044). After accounting for the effect of prior restenosis (P = 0.005) and saphenous vein site (P = 0.006) in multivariate testing, lesion severity at follow-up was still less with the Palmaz-Schatz stent (P = 0.037).
