- A steep rise in the use of transcatheter aortic valve implantation (TAVI) for the management of symptomatic severe aortic stenosis occurred. Minimalist TAVI procedures and streamlined patient pathways within experienced Heart Valve Centres are designed to overcome the challenges of ever-increasing procedural volume.The 2022 European TAVI Pathway Survey aims to describe contemporary TAVI practice across Europe.Between October and December 2022, TAVI operators from 32 European countries were invited to complete an online questionnaire regarding their current practice.Responses were available from 147 TAVI centres in 26 countries. In 2021, the participating centres performed a total number of 27,223 TAVI procedures, with a mean of 185 TAVI cases per centre (median 138; IQR 77-194). Treatment strategies are usually (87%) discussed at a dedicated Heart Team meeting. Transfemoral TAVI is performed with local anaesthesia only (33%), with associated conscious sedation (60%), or under general anaesthesia (7%). Primary vascular access is percutaneous transfemoral (99%) with secondary radial access (52%). After uncomplicated TAVI, patients are transferred to a high-, medium-, or low-care unit in 28%, 52%, and 20% of cases, respectively. Time to discharge is day 1 (12%), day 2 (31%), day 3 (29%), or day 4 or more (28%).Reported adoption of minimalist TAVI techniques is common among European TAVI centres, but rates of next-day discharge remain low. This survey highlights the significant progress made in refining TAVI treatment and pathways in recent years and identifies possible areas for further improvement.

- BACKGROUND:Left ventricular (LV) hypertrophy is associated with LV diastolic dysfunction and constitutes a risk factor for cardiac morbidity and mortality. The objective of this study was to investigate the degree of LV mass regression and the changes of LV diastolic function one year after transcatheter aortic valve implantation (TAVI).METHODS:Echocardiography was performed at baseline, before discharge, and at one-year follow-up in 63 consecutive patients with severe aortic stenosis who underwent TAVI with the Medtronic CoreValve System (Medtronic Inc, Minneapolis, MN). The LV mass was calculated using the Devereux formula and indexed to body surface area.RESULTS:One-year all-cause mortality was 29%. The LV mass index decreased from 126 ± 42 g/m2 at baseline to 110 ± 30 g/m2 at one-year follow-up (p < 0.001). Left ventricular ejection fraction and LV diastolic function did not change significantly. Mean transaortic gradient decreased from 47 ± 19 mm Hg at baseline to 9 ± 5 mm Hg at discharge and 9 ± 4 mm Hg at one year (p < 0.001), and was accompanied by significant clinical improvement. More than mild paravalvular aortic regurgitation was found in 24% and 15% of patients at discharge and one-year follow-up, respectively.CONCLUSIONS:A significant regression in LV mass was found one year after TAVI. However, regression was incomplete and was not accompanied by an improvement in LV diastolic function.

- The increasing interest in left atrial appendage occlusion (LAAO) for ischaemic stroke prevention in atrial fibrillation (AF) fuels the need for more clinical data on the safety and effectiveness of this therapy. Besides an assessment of the effectiveness of the therapy in specific patients groups, comparisons with pharmacological stroke prophylaxis, surgical approaches, and other device-based therapies are warranted. This paper documents the consensus reached among clinical experts in relevant disciplines from Europe and North America, European cardiology professional societies, and representatives from the medical device industry regarding definitions for parameters and endpoints to be assessed in clinical studies. Adherence to these definitions is proposed in order to achieve a consistent approach across clinical studies on LAAO among the involved stakeholders and various clinical disciplines and thereby facilitate continued evaluation of therapeutic strategies available.
