Abstract 4345: Serial Angiographic Follow-up After Successful Implantation of Sirolimus-Eluting Stent and Paclitaxel-Eluting Stent for Chronic Total Occlusions: Multicenter Registry in Asia
Purpose: To evaluate the long-term efficacy of Sirolimus-eluting stent (SES) and Paclitaxel-eluting stent (PES) on the outcome of patients with chronic total occlusions (CTO).
Methods: A total of 210 patients with 232 CTO lesions (male 70.5%, mean age 70.8 yrs, LAD 50.9%, LCX 21.6%, RCA 25.0%, Others 2.5%) were treated with SES (102 patients 118 lesions, mean lesion length 36.1±12.9 mm, mean stent length 41.7±15.6mm) and PES (108 patients 114 lesions, mean lesion length 38.5±12.8 mm, mean stent length 43.9±19.5 mm). We conducted follow-up coronary angiogram in all patients after successful implantation of SES and PES (9, 12, 18, 24 months respectively)
Results: The baseline clinical characteristics between 2 groups were similar. See table⇓ for clinical results.
Conclusion: There is a different timing of late catch up phenomenon (late lumen loss) of SES and PES (SES: 12–18 months, PES: 9 –12 months) after successful implantation of SES and PES in patients with chronic total occlusion. Patients treated with SES showed lesser loss of minimum lumen diameter compared with PES.
