Objectives: Treatment decisions for severe aortic stenosis (AS) are complex, since there are two active and comparable options: transcatheter aortic valve implantation and surgical aortic valve replacement. The disease predominantly affects older individuals, who are frequently comorbid with from cognitive impairment. This study aimed to establish a screening-triggered system to assess the decision-making capacity of patients with AS, support their decision-making, and facilitate referrals to specialists when necessary.
Methods: This is a retrospective pre-post observational study. Relevant healthcare professionals were trained to assess and support patients' decision-making capacities.
Results: Subtotals of 203 and 244 patients were enrolled before and after the implementation of the system, respectively. The requests for decision-making support significantly increased (from 1.5 % to 14.8 % of the patients). 11.5 % of the patients were identified as with declined decision-making capacity. The proportion of patients who received active treatments for AS significantly decreased from 95.0 % to 83.0 %. The nurses' documentation of patients' decision-making capacities significantly increased.
Conclusion: This screening-triggered system identified a substantial proportion of patients with declined decision-making capacity. A significant decrease in patients receiving active treatments for AS and increased documentation of patients' decision-making capacities in nursing records were observed. A future randomized controlled is warranted.

Patients with coronary artery disease undergoing trans-catheter aortic valve implantation (TAVI) often receive TAVI alone. However, in cases of severe coronary lesions or anticipated difficulty in coronary access post-TAVI, percutaneous coronary intervention or coronary artery bypass grafting may be necessary. We performed simultaneous gastroepiploic artery to posterior descending artery bypass and TAVI in two patients with severe calcification of the right coronary artery ostium which is unsuitable for percutaneous intervention.

Transcatheter aortic valve implantation (TAVI) using the NAVITOR system has been relatively underreported due to its recent introduction in Japan. This study aimed to assess the short-term outcomes of TAVI with the NAVITOR in real-world clinical practice. Patients with severe aortic stenosis who underwent TAVI using the NAVITOR system at our institution between December 2022 and December 2023 were prospectively enrolled.

Introduction: Transcatheter aortic valve replacement (TAVR) is increasingly in demand for treating severe aortic stenosis in a variety of surgical risk profiles. This means increasing wait times and elevated morbidity and mortality on the waitlist. To address this, we developed the SWIFT TAVR algorithm to prioritize patients based on clinical risk and reduce wait times.

Purpose: Cardiac computed tomography angiography (CCTA) has significantly advanced the visualization of cardiac structures, particularly valves. We assessed the diagnostic performance of CCTA in diagnosing the most common disorders affecting the aortic valves requiring surgery-papillary fibroelastoma, infective endocarditis, and degeneration.
Methods: This retrospective study included patients who underwent aortic valve resection between 2016 and 2023 and had a preceding CCTA.

Importance: It remains unknown whether outcomes of the Placement of Aortic Transcatheter Valves 3 (PARTNER 3) and Evolut Low Risk trials are comparable with surgical outcomes in nontrial settings, considering the added risk of concomitant cardiac operations.
Objective: To compare 30-day mortality and stroke incidences of patients in the surgical aortic valve replacement (SAVR) arm of low-risk trials with those of similar patients in the US Society of Thoracic Surgeons Adult Cardiac Surgery Database (STS ACSD).
Design, Setting, And Participants: A cross-sectional sampling study was conducted of adults in the STS ACSD with severe aortic stenosis at low surgical risk for AVR who underwent SAVR during the years low-risk AVR trials (PARTNER 3 and Evolut Low Risk) were enrolling (calendar years 2016-2018).
