Changes in demographics, treatment and outcomes in a  consecutive cohort who underwent transcatheter aortic valve implantation between 2005 and 2020
CONCLUSION: Over our 15 years' experience, patient age remained unchanged but the patient risk profile became more favourable. Simplification of the TAVI procedure occurred in parallel with major improvement in outcomes and survival. Bleeding/vascular complications and the need for pacemaker implantation remain the Achilles' heel of TAVI.PMID:35212972 | DOI:10.1007/s12471-022-01662-2

Randomised comparison of a  balloon-expandable and self-expandable valve with quantitative assessment of aortic regurgitation using magnetic resonance imaging.
CONCLUSIONS: The use of the latest generation of BEV was associated with less AR as quantitatively assessed by MRI. Although the use of MRI to quantify AR is not feasible in daily clinical practice, it should be considered as a surrogate endpoint for clinical outcomes in comparative studies of valves for TAVI.

Safety and efficacy of a self-expanding versus a balloon-expandable bioprosthesis for transcatheter aortic valve replacement in patients with symptomatic severe aortic stenosis: a randomised non-inferiority trial
Publication date: Available online 27 September 2019Source: The LancetAuthor(s): Jonas Lanz, Won-Keun Kim, Thomas Walther, Christof Burgdorf, Helge Möllmann, Axel Linke, Simon Redwood, Christian Thilo, Michael Hilker, Michael Joner, Holger Thiele, Lars Conzelmann, Lenard Conradi, Sebastian Kerber, Gerhard Schymik, Bernard Prendergast, Oliver Husser, Stefan Stortecky, Dik Heg, Peter JüniSummaryBackgroundTranscatheter aortic valve replacement (TAVR) is the preferred treatment option for older patients with symptomatic severe aortic stenosis. Differences in the properties of available TAVR systems can affect clinical outcom...

Hemodynamics of paradoxical severe aortic stenosis: insight from a pressure –volume loop analysis
ConclusionsThe present study suggests that the hemodynamics of PLFLG AS can be explained by two mechanisms: (1) stiffness of the small left ventricle with reduced contractility, and (2) increased afterload due to the impairment of vascular function. Both mechanisms have similarities to those of heart failure with preserved EF. This type of remodeling may explain the poor prognosis of PLFLG AS.

Medtronic wins CE Mark for CoreValve Evolut Pro
Medtronic (NYSE:MDT) said today it won CE Mark approval in the European Union for its CoreValve Evolut Pro transcatheter aortic heart valve, indicated for the treatment of severe aortic stenosis for symptomatic patients at intermediate, high or extreme risk for open heart surgery The CoreValve Evolut Pro features an outer wrap to add surface area contact between the valve and the native aortic annulus to increase valve sealing performance, Fridley, Minn.-based Medtronic said. “We are excited to introduce the next evolution of our Evolut TAVI platform to provide physicians in Europe with a comprehensive portfolio to ...
