ABSTRACT
OBJECTIVES:
Initial and late results after implantation of Freedom stents, a balloon expandable stainless steel coil stents were evaluated.METHODS:
From Jun. 1996 to Nov. 1997, we implanted 123 Freedom stents in 122 lesions in 117 patients and performed follow-up coronary angiograms at 7.0 3.6 months after stents placement. Clinical courses after stenting and follow-up coronary angiographic findings were evaluated. Comparison of clinical, angiographic, and procedural factors according to the presence or absence of restenosis was performed.RESULTS:
In 117 patients who underwent stents implantation, major complications were not observed. Follow-up coronary angiograms were performed in 47 stents in 41 patients (35+ACU-). Among 47 stents, angiographic significant restenosis (percent diameter stenosis +AD4- 50+ACU-) was observed in 13 (28+ACU-). Mean age in 41 patients was 59 9 years, with 27 male patients (66+ACU-). Indications for stents implantation were de novo lesions in 18 (38+ACU-), suboptimal results after PTCA in 18 (38+ACU-), bail-out lesions in 4 (9+ACU-) and restenotic lesions in 7 (15+ACU-). Lesion types by AHA/ACC classification were A in 1 (1+ACU-), B1 in 10 (21+ACU-), B2 in 17 (36+ACU-), and C in 19 (40+ACU-). Average lesion length was 13.7 9.0 mm, stent diameter 3.0 0.3 mm, and stent length 24.6 9.0 mm. There were no significant differences of the clinical, angiographic, and procedural characteristics according to the presence or absence of restenosis.CONCLUSION:
Freedom coronary stents implantation is safely performed in various morphology of coronary lesions and no significant predictive factors on restenosis in follow-up coronary angiogram were observed.
