Type 5 phosphodiesterase (PDE5) and the vascular tree: from embryogenesis to aging and disease

2020

Highlights • Vascular development depends on the timely differentiation of endothelial and smooth muscle cells, that mutually influence their developmental fate. • Endothelial and vascular smooth muscle cell (VSMC) compartments can mutually influence cell and tissue modifications during vascular aging and in vascular disease. • Keeping in mind that PDE5 is mainly expressed in VSMCs, we surveyed the literature on the role of PDE5 in vascular development, aging and disease. • Although most results have been obtained by PDE5 pharmacological inhibition, no data are available, to date, on vascular development, aging or disease following PDE5 genetic ablation.

Contemporary practice and technical aspects in coronary intervention with bioresorbable scaffolds : a European perspective

2015

Aims Next to patient characteristics, the lack of a standardised approach for bioresorbable vascular scaffold (BVS) implantation is perceived as a potential explanation for the heterogeneous results reported so far. To provide some guidance, we sought to find a consensus on the best practices for BVS implantation and management across a broad array of patient and lesion scenarios. Methods and results Fourteen European centres with a high volume of BVS procedures combined their efforts in an informal collaboration. To get the most objective snapshot of different practices among the participating centres, a survey with 45 multiple choice questions was prepared and conducted. The results of th…

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

2016

Aims: We aimed to investigate the outcomes of bioresorbable vascular scaffolds (BVS) in coronary ostial lesions. Ostial lesions represent a challenging angiographic subset, with higher event rates compared with non-ostial lesions. BVS might be associated with advantages over the long term, but their safety in this setting remains to be explored. Methods and results: Procedural and 12-month follow-up data from consecutive patients treated with BVS for lesions located at the ostium of the right (RCA), left anterior (LAD) or circumflex (LCX) coronary in 11 European centres were collected. The primary device-oriented endpoint was defined as a combination of cardiovascular death, target vessel m…

The database included a total of 1549 lesions in 1304 patients with a mean age of 62 +/- 11years. There were 90 ostial lesions (5.8%) in 84 patients (6.4%) located at the ostial RCA (14; 16%) LCX (29; 32%) or LAD (47; 52%). Patients presenting with ostial lesions did not differ from the remaining cohort except for a higher incidence of prior revascularisation. 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% [23-41] 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 [362-465] days. The 12-month Kaplan-Meier estimated rates of scaffold thrombosis were 4.9% and 2.0% (ostial and non-ostial lesion groups respectively log-rank p= 0.005). The device-oriented composite endpoint occurred respectively in 12.6% and 4.6% at 12 months (log-rank p= 0.001).

Bioresorbable vascular scaffold versus everolimus-eluting stents or drug eluting balloon for the treatment of coronary in-stent restenosis: 1-Year fo…

2017

Objectives to compare the 1-year outcome between bioresorbable vascular scaffold (BVS), everolimus-eluting stent (EES), and drug-eluting balloon (DEB) for in-stent restenosis (ISR) treatment. Background BVS has been proposed as alternative for ISR treatment. To date a direct comparison between BVS and DES or DEB for ISR treatment is lacking. Methods We retrospectively analyzed all ISR lesions treated with BVS, DEB, and EES from January 2012 to December 2014. A total of 548 lesions (498 patients) were included. By applying two propensity-score matching, 93 lesions treated with BVS were compared with 93 lesions treated with DEB, and 100 lesions treated with BVS were compared to 100 lesions tr…

Clinical outcomes of patients with diabetes mellitus treated with Absorb bioresorbable vascular scaffolds: a subanalysis of the European Multicentre …

2017

Background Data on the clinical performance of bioresorbable scaffolds in patients with diabetes mellitus (DM) are still limited. The present study reported 1-year clinical outcomes associated with the use of everolimus-eluting bioresorbable vascular scaffolds (Absorb BVS; Abbott Vascular, Santa Clara, CA) in DM patients. Methods and Results This was a subanalysis from the GHOST-EU (Gauging coronary Healing with biOresorbable Scaffolding plaTforms in Europe) multicenter retrospective registry including patients treated with Absorb BVS between November 2011 and September 2014. In this study, a comparative analysis stratified according to DM was performed. The primary endpoint was target lesi…

Effect of implantation technique on outcomes in patients receiving bioresorbable scaffolds in various clinical scenarios

2021

ABSTRACT Introduction and objectives: The PSP (pre-dilation, sizing and post-dilation) score, derived from the GHOST-EU registry, has evaluated the relationship between the implantation technique of bioresorbable scaffolds and the clinical outcomes. The objective was to perform an external validation of the PSP technique and to determine its effect on adverse cardiac events in various clinical and anatomical scenarios. Methods: Data from the REPARA registry (2230 patients) were used for external validation, whereas a common database combining REPARA and GHOST-EU (3250 patients) data was used to evaluate the effect of PSP technique in various clinical and anatomical scenarios. PSP-1 and PSP-…
