  • One-year outcomes after transcatheter aortic valve implantation with the latest-generation SAPIEN balloonexpandable valve : the S3U registry
  • 2023
  • Ingår i: EuroIntervention. - : Europa Digital & Publishing. - 1774-024X .- 1969-6213. ; 18:17, s. 1418-

    • Background: Initial data about the performance of the new-generation SAPIEN 3 Ultra (S3U) valve are highly promising. However, evidence about the longer-term performance and safety of the S3U is scarce.Aims: We aimed to investigate the 1-year clinical and echocardiographic outcomes of transcatheter aortic valve implantation (TAVI) using the S3U compared with its predecessor, the SAPIEN 3 valve (S3).Methods: The SAPIEN 3 Ultra registry included consecutive patients who underwent transfemoral TAVI at 12 European centres with the S3U or S3 between October 2016 and December 2020. One-to-one propensity score (PS) matching was performed to account for differences in baseline characteristics. The primary outcomes of interest were all-cause death and the composite of all-cause death, disabling stroke and hospitalisation for heart failure at 1 year.Results: The overall study cohort encompassed 1,692 patients treated with either the S3U (n=519) or S3 (n=1,173). The PS-matched population had a total of 992 patients (496 per group). At 1 year, the rate of death from any cause was 4.9% in the S3U group and 6.3% in the S3 group (p=0.743). Similarly, there were no significant differences in the rates of the primary composite outcome (9.5% in the S3 group and 6.6% in the S3U group; p=0.162). The S3U was associated with lower rates of mild paravalvular leak (PVL) compared with the S3 (odds ratio 0.63, 95% confidence interval: 0.44 to 0.88; p<0.01). No significant differences in transprosthetic gradients were observed between the two groups.Conclusions: Compared with the S3, the S3U transcatheter heart valve was associated with similar 1-year clinical outcomes but reduced rates of mild PVL.

  • Quality and Utility of European Cardiovascular and Orthopaedic Registries for the Regulatory Evaluation of Medical Device Safety and Performance Across the Implant Lifecycle : A Systematic Review
  • 2023
  • Ingår i: International Journal of Health Policy and Management. - : Kerman University of Medical Sciences. - 2322-5939. ; 12:1, s. 1-11
  • Forskningsöversikt (refereegranskat)abstract
    • Background: The European Union Medical Device Regulation (MDR) requires manufacturers to undertake post-market clinical follow-up (PMCF) to assess the safety and performance of their devices following approval and Conformite Europeenne (CE) marking. The quality and reliability of device registries for this Regulation have not been reported. As part of the Coordinating Research and Evidence for Medical Devices (CORE-MD) project, we identified and reviewed European cardiovascular and orthopaedic registries to assess their structures, methods, and suitability as data sources for regulatory purposes.Methods: Regional, national and multi-country European cardiovascular (coronary stents and valve repair/replacement) and orthopaedic (hip/knee prostheses) registries were identified using a systematic literature search. Annual reports, peer-reviewed publications, and websites were reviewed to extract publicly available information for 33 items related to structure and methodology in six domains and also for reported outcomes.Results: Of the 20 cardiovascular and 26 orthopaedic registries fulfilling eligibility criteria, a median of 33% (IQR: 14%-71%) items for cardiovascular and 60% (IQR: 28%-100%) items for orthopaedic registries were reported, with large variation across domains. For instance, no cardiovascular and 16 (62%) orthopaedic registries reported patient/ procedure-level completeness. No cardiovascular and 5 (19%) orthopaedic registries reported outlier performances of devices, but each with a different outlier definition. There was large heterogeneity in reporting on items, outcomes, definitions of outcomes, and follow-up durations.Conclusion: European cardiovascular and orthopaedic device registries could improve their potential as data sources for regulatory purposes by reaching consensus on standardised reporting of structural and methodological characteristics to judge the quality of the evidence as well as outcomes.

  • Fully independent external validation of the Transcatheter Aortic Valve Replacement 30-day (TAVR-30) hospital readmission model
  • 2023
  • Ingår i: Cardiovascular Revascularization Medicine. - : Elsevier. - 1553-8389 .- 1878-0938. ; 56, s. 9-15
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Early and late readmissions after Transcatheter Aortic Valve Replacement (TAVR) are common and associated with worse outcome. A risk prediction model (TAVR-30) was recently developed using readily available clinical variables to identify patients at risk for hospital readmission within 30 days after TAVR. We performed an independent external validation of the TAVR-30 model.Methods: The Swedish TAVR-registry, linked together with other mandatory national registries was used to identify all TAVR procedures, variables from the original model, hospitalizations and deaths between the years 2008 to 2021.Results: A total of 8459 patients underwent TAVR, 7693 patients had complete data and were included in the analysis. Out of these, 928 patients experienced a readmission within 30 days. Using the estimates from the original model, a concordance (c)-index of 0.51, a calibration slope of 0.07 and intercept of −0.62 were obtained respectively, overall implying poor model performance.Conclusions: This independent external validation indicates poor performance of the TAVR-30 model in a Swedish setting. Further research is needed to develop more reliable tools for predicting the risk of early hospital readmission after TAVR, as well as, for providing a deeper understanding of how to develop risk models that performs well in patients with multiple underlying comorbidities.
