Abstract

BACKGROUND AND OBJECTIVES: This prospective single-center randomized clinical study was designed to evaluate the long-term angiographic and clinical outcomes of elective treatment using the Crossflex (coil stent) as compared with the NIR (tubular stent) in patients with native coronary artery disease.
SUBJECTS AND METHODS
104 patients with 107 de novo discrete coronary stenoses were randomly assigned to the NIR stent (54 coronary stenoses) or the Crossflex stent (53 coronary stenoses). Six-month follow-up angiograms were obtained in 83 patients with 86 lesions (80%). Clinical follow up was available in all patients and the period averaged 23.1+/-5.3 months in the Crossflex group and 23.1+/-6.2 months in the NIR group.
RESULTS
Procedural success was measured at 100% in both groups. There were no cases of stent thrombosis in either group. Although a higher loss index and more severe follow-up diameter stenosis occurred in the crossflex group, the angiographic restenosis rate was not significantly different in between the groups.
