Clinical outcome of patients with implantation of second‐generation drug‐eluting stents in the right coronary ostium: Insights from 2‐year follow‐up of the TWENTE trial

Abstract

AO treatment of the RCA with second-generation DES is feasible, but our data suggest that stent coverage of the right AO segment remains a predictor of TLR.

Early and midterm outcomes of bioresorbable vascular scaffolds for ostial coronary lesions: insights from the GHOST-EU registry

“…The importance of these procedures is now better understood. There was no DES-treated control group, and the heterogeneity in the protocols, cohorts under study, and outcomes of previously published studies complicates any comparison 11,[22][23][24][25][26][27][28][29] . In addition, operator preference at the time of the choice of the device (BVS versus DES) might have introduced a patient/lesion selection bias.…”

“…Predilation was performed in 97% of the lesions (vs. 96% in non-ostial, p=0.618), post-dilation in 43% (versus 58% in the non-ostial group, p=0.008). At quantitative coronary angiography, treatment of ostial lesions was associated with higher residual stenosis (30% [23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41] vs. 26% [20-37], p=0.035), but no difference in minimum lumen diameter existed (p=0.447). Follow-up data were available at 385 days.…”

Comparison of mid-term clinical outcomes between “complete full-metal jacket strategy” versus “incomplete full-metal jacket strategy” for diffuse right coronary artery stenosis with drug-eluting stents

“…The short-and long-term outcomes of PCI for RCA ostium have been unsatisfactory since the bare metal stent (BMS) era [16,17]. Although the clinical outcomes in PCI have significantly improved in the DES era compared to the BMS era [18], stenting to RCA ostium is still a predictor of TLR even using the second-generation DES [19]. This may be partly explained by the rigid nature of the vessel wall in the coronary ostium [20].…”

Comparison of early‐ and new‐generation drug‐eluting stent implantations for ostial right coronary artery lesions

“…In the era of nDES use, Lam et al. reported the feasibility of treating RCA aorto‐ostial lesions with nDES . However, not much are data available that directly compare clinical outcomes between nDES and eDES implantation for ostial RCA lesions.…”
