cardihg y 1 Influence of Vessel Selection on the Observed Restenosis Rate After Endoluminal Stenting or Directional Atherectomy Richard E. Kuntz, MD, MS, Tomoaki Hinohara, MD, Gregory C. Robertson, MD, Robert D. Safian, MD, John B. Simpson, MD, PhD, and Donald S. Bairn, MD
in comparing the restenosis rates among different interventions, 1 potential confounder might be the differences in the vessels treated, as dictated by the technkai lhnRations of partkular devices. Yhe purpose of this study was to use current “acute gaitite toss” analysis to examine what influence vessel selection has on the restenosis rates seen after coronary stenting or directional atherectomy. Yhe minimal hrmhral diameter of native coronary testons was measured before and immediately after intervention in 102 sbrgle Palmaz6chatz stents and 347 atherectomies, 367 (62%) of whkh had repeat angiographk measurement 6 months after interventton. Atherectomy-treated Iedons had a higher proportion of left anterior descending to right coronary arteries (66 vs 24%) compared with stents (31 VI 64%), p
