Anatomy of Risk: Decoding the Predictors of Vascular Access Complications in Transcatheter Aortic Valve Replacement.
Catheter Cardiovasc Interv
December 2024
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.
Hypoxia-inducible factor prolyl hydroxylase inhibitor-induced thrombosis leading to transcatheter aortic valve dysfunction: a case report.
Eur Heart J Case Rep
January 2025
Department of Cardiovascular Medicine, Kurashiki Central Hospital, Kurashiki, Japan.
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.
Potential of right ventricular function assessment with echocardiography in transcatheter aortic valve replacement.
J Cardiothorac Surg
December 2024
Department of Cardiology, Thomas Jefferson University, Philadelphia, PA, 19107, USA.
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.

Section of Cardiology, Department of Medicine, Baylor College of Medicine, Houston, TX, USA. Electronic address:
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.

CJC Open
December 2024
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).
