Transcatheter aortic valve implantation (TAVI) is the treatment of choice for symptomatic aortic stenosis in patients with moderate to high surgical risk. When transfemoral access is unsuitable, alternative routes such as transapical (TAP) or transaxillary (TAX) routes must be considered. This study compares the in-hospital mortality and clinical outcomes of TAP vs.

- Intra-atrial shunts are linked to a higher risk of embolic strokes, and this study compares outcomes of shunt occlusion between younger (≤50 years) and older (>50 years) patients with a history of paradoxical embolism.
- The study analyzed data from 187 patients who underwent shunt occlusion from 2013 to 2023, revealing that older patients had more cardiovascular risk factors but similar shunt characteristics and procedural outcomes compared to younger patients.
- Follow-up results showed low recurrence rates of arterial embolism and no significant outcome differences between high-volume and low-volume shunts in older patients, suggesting similar safety and efficacy for both age groups.
Article Synopsis
- Percutaneous interventional left atrial appendage occlusion (LAAO) is a proven method for preventing strokes in patients with atrial fibrillation (AF) and has been evaluated in a study involving 149 patients at a Berlin hospital from 2016 to 2022.
- The study compared two types of devices used in LAAO: single-occlusive plug-type (SOPT) and dual-occlusive disc-type (DODT), noting that while DODT procedures took longer, both had successful implantation with low rates of complications and no hospital deaths.
- After six months, findings indicated that SOPT had a higher rate of device-related thrombus formation compared
Introduction: There is a lack of real-world data directly comparing different valve prostheses for transaortic valve replacement (TAVR). We aimed to compare early clinical outcomes at 30-days between the self-expandable Portico valve (Abbott) with the balloon-expandable Edwards Sapien 3 valve (Edwards Lifesciences) (ES3).
Methods: Out of 1,901 patients undergoing TAVR between January 2018 and December 2021, all patients who received either Portico valve or ES3 valve via transfemoral TAVR were matched using nearest-neighbor (1:1) propensity scoring.
Background: Range-of-motion (ROM) data generated by the in vitro test methods of spine simulators with cadavers (SSCs) and finite element models (FEMs) are used alternatively and complementarily for in vitro evaluations.
Aim Of Review: Our purpose is to compare exemplary segmental ROM data from SSCs and FEMs before and after ball-and-socket total disc replacement (bsTDR) to determine whether the two test methods provide the same data for the same evaluation subjects.
Key Scientific Concepts Of Review: We performed 70 meta-analyses (MAs) and 20 additional comparative analyses based on data from 21 SSC studies used for 39 MAs and 16 FEM studies used for 31 MAs.
