Background: For nonagenarians with symptomatic severe aortic stenosis transcatheter aortic valve implantation (TAVI) has become a feasible therapeutic option. Therefore, the aim of this study was to evaluate the procedural outcomes and mid-term follow-up in this patient group and compare this to octogenarians.
Methods: From 1359 patients who underwent TAVI at our institution between March 2009 and February 2016, 82 patients were nonagenarians and 912 were octogenarians. In nonagenarians, mean age was 91.9±1.4years and compared to octogenarians showed a significantly higher logistic EuroScore (27.7±14.8% vs. 23.1±14.4, p=0.005) and STS Score (8.5±4.8% vs. 6.3±6.7, p=0.001).
Results: There were no significant differences with regard to stroke rate, pacemaker implantation rate and major vascular complications between the two groups. Thirty-day mortality was 9.8% in nonagenarians and 4.1% in octogenarians (p=0.04). At 1 year, all-cause mortality increased to 30.9% vs. 18.6% (n.s.).
Conclusion: Nonagenarians showed an increased periprocedural mortality during TAVI and higher mortality in follow-up compared to octogenarians. Age alone is not a predictive factor but indication for treatment should be carefully evaluated by the heart team on an individual basis.

Department of Surgery, University of North Dakota School of Medicine and Health Sciences, Grand Forks, North Dakota, United States.
Background: Despite advancements in valve implantation devices, vascular access complications (VAC) remain a significant cause of morbidity and mortality for those undergoing transcatheter aortic valve replacement (TAVR). We describe pre-operative imaging analysis of the aortoiliac and femoral arterial beds using the TransAtlantic intersociety consensus (TASC) score, ilio-femoral tortuosity, and procedural characteristics to identify anatomic risk factors predictive of VAC in TAVR.
Methods: Consecutive patients undergoing TAVR from 2012 to 2022 at a single North Dakota hospital were retrospectively reviewed.

Background: Transcatheter aortic valve replacement (TAVR) is a well-established treatment option for patients with severe aortic valve stenosis; however, clinical valve thrombosis is a major challenge.
Case Summary: A 92-year-old woman underwent TAVR for severe aortic stenosis. One month later, the patient developed acute heart failure.

Background: Right ventricular (RV) function assessment by echocardiography can be challenging due to its complex morphology. Also, increasing use of sedation rather than general anesthesia for transfemoral approach transcatheter aortic valve replacement (TAVR) reduces the need for intraoperative transesophageal echocardiography (TEE). Recent clinical studies have demonstrated the importance of 3-dimensional (3D) echocardiography and a longitudinal strain for RV function assessment.

Leaflet thrombosis after transcatheter aortic valve replacement (TAVR) presents a significant challenge, leading to adverse clinical outcomes. Subclinical leaflet thrombosis (SLT) is increasingly recognized, and there is a growing concern about its role in clinical events and hemodynamic valve deterioration. Current recommendations for prophylactic anticoagulation or antiplatelet therapy following TAVR are primarily based on expert consensus rather than definitive evidence from randomized trials, resulting in a variety of antithrombotic strategies in clinical practice.

Department of Cardiology, Keio University School of Medicine, Tokyo, Japan.
Background: The short-term and midterm impact of gender differences on transcatheter aortic valve implantation (TAVI) has been studied. However, the impact on long-term clinical outcomes remains unclear. The objective of the study was to investigate the impact of gender differences after TAVI on long-term clinical outcomes and structural valve deterioration (SVD).
