  • Beschreibung: <jats:p>Background: After stent implantation at the right coronary artery (RCA) ostial site, in-stent restenosis (ISR) often occurs and target lesion revascularization (TLR) is required. But at the RCA ostial site, the impact of stent fracture(SF) or stent recoil(SR) on midterm and especially late term restenosis is unknown.</jats:p> <jats:p>Methods: From March 2004 to June 2010, 129 RCA ostial sites were successfully treated with 3 types of drug-eluting stent: sirolimus-eluting stent (SES), n=74; paclitaxel-eluting stent (PES), 39; everolimus-eluting stent (EES), 16. Mid and late term follow-up coronary angiography(CAG) was performed at 8 months and after 20 months. And SF and SR were assessed. We defined SF as apparent strut separation and SR as axial recoil less than 80% in the stent diameter, both analyzed by coronary angiography.</jats:p> <jats:p>Results: We found 41 SF lesions (31.8%) and 24 SR lesions (18.6%) at the 8months follow up CAG. Out of the 102 patients without ISR at the 8months CAG, we were able to follow up 86 patients until the late term. The data of ISR and TLR at 8month and ISR at late term are shown in the table.</jats:p> <jats:p>Conclusion: At the RCA ostial site, SF and SR have an effect on the ISR and TLR at 8month. Furthermore SF and SR have impact on late term ISR consecutively.</jats:p> <jats:p> <jats:inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="g18633_1.jpeg" /> </jats:p> <jats:p> <jats:inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="g18633_2.jpeg" /> </jats:p> <jats:p> <jats:inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="g18633_3.jpeg" /> </jats:p>
