Outcomes of transcatheter aortic valve replacement at teaching versus nonteaching hospitals - PubMed
Source : https://pubmed.ncbi.nlm.nih.gov/36073067/
With the evolution and expansion of TAVR to nonteaching centers, mortality, and readmission rates are not significantly different between nonteaching and teaching hospitals. Higher unadjusted in-hospital mortality at teaching centers...
Conclusion: With the evolution and expansion of TAVR to nonteaching centers, mortality, and readmission rates are not significantly different between nonteaching and teaching hospitals. Higher unadjusted in-hospital mortality at teaching centers suggest these centers more often treat high risk patients with associated increased complications.
Validation of reliability and predictivity of membrane septum length measurements for pacemaker need after transcatheter aortic valve replacement - PubMed
Source : https://pubmed.ncbi.nlm.nih.gov/36073020/
External validity and predictive accuracy of MS length for PMI after TAVR were not sufficient to provide better risk stratification over the established predictors in our cohort. Moreover, the ID...
Conclusions: External validity and predictive accuracy of MS length for PMI after TAVR were not sufficient to provide better risk stratification over the established predictors in our cohort. Moreover, the ID and ΔMSID, but not MS length alone, are predictive of future PMI after TAVR.
Advances in technology and techniques for transcatheter aortic valve replacement with concomitant peripheral arterial disease
Source : https://www.frontiersin.org/articles/10.3389/fmedt.2022.959249/full
Aortic stenosis (AS) is a prevalent disease affecting 3.7% of the adult population aged 65 or above. In the past, surgical aortic valve replacement (SAVR) was the only definitive therapy...
Relevance:In this review, the prevalence and outcome of TAVR patients with PAD will be discussed. Furthermore, novel technologies and techniques that enable TAVR to be safely performed using transfemoral or alternative access in patients with severe PAD will be reviewed.
Structural analysis of regional transcatheter aortic valve underexpansion and its implications for subclinical leaflet thrombosis - PubMed

Conclusion/Relevance: The study improves our understanding of the effects of regional stent under-expansion in TAVR. Post-procedural balloon dilatation of self-expanding TAVs can potentially be advantageous in reducing leaflet distortion and normalizing leaflet stress distribution. Large-scale, prospective, and well-controlled studies are needed...
Valve-in-valve TAVR using BASILICA technique and cerebral protection in a patient with severe dysfunction of the aortic bioprosthesis
Source : https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9421518/
Transcatheter aortic valve replacement (TAVR) is recommended for high- and intermediate-risk patients with severe aortic stenosis and a suitable option for degenerated surgical bioprosthetic valves. The feasibility of a complete...
Conclusion/Relevance: BASILICA is a novel transcatheter electrosurgical technique which increases the safety of ViV TAVR, but also enhances the risk of stroke [3]. Thus, the use of a cerebral protection device (CPD) has been advocated when performing BASILICA prior to TAVR
