Clinical value of aortic arch morphology in transfemoral TAVR: artificial intelligence evaluation.
Int J Surg
January 2025
Department of Cardiovascular Surgery, Xijing Hospital, Xi'an, Shaanxi, China.
Background: The impact of aortic arch (AA) morphology on the management of the procedural details and the clinical outcomes of the transfemoral artery (TF)-transcatheter aortic valve replacement (TAVR) has not been evaluated. The goal of this study was to evaluate the AA morphology of patients who had TF-TAVR using an artificial intelligence algorithm and then to evaluate its predictive value for clinical outcomes.
Materials And Methods: A total of 1480 consecutive patients undergoing TF-TAVR using a new-generation transcatheter heart valve at 12 institutes were included in this retrospective study.
Redo Surgical Aortic Valve Replacement versus Valve-in-Valve Transcatheter Aortic Valve Replacement for Degenerated Bioprosthetic Valves.
Ann Thorac Surg
January 2025
Division of Cardiothoracic Surgery, University of Virginia Health University Hospital, Charlottesville, VA.
Background: Valve-in-valve transcatheter aortic valve replacement (ViV-TAVR) is associated with improved perioperative safety compared to redo surgical aortic valve replacement (redo-SAVR), but long-term outcomes remain uncertain. We therefore compare long-term outcomes of ViV-TAVR and redo-SAVR.
Methods: The study included 1:1 propensity-matched Medicare beneficiaries with degenerated bioprosthetic valves admitted between 09/29/2011 and 12/30/2020 undergoing either redo-SAVR or ViV-TAVR.
Long-Term Clinical Impact of Paravalvular Leak Following Transcatheter Aortic Valve Implantation.
J Clin Med
January 2025
National Center for Global Health, Istituto Superiore di Sanitá, 00161 Rome, Italy.
Paravalvular leak (PVL) was initially recognized as one of the most common complications after transcatheter aortic valve implantation (TAVI) and has been linked to adverse clinical outcomes, including mortality. This study aims to assess the long-term clinical effects of PVL in patients undergoing TAVI with the latest generation of transcatheter aortic valves, as part of the national observational prospective multicenter study OBSERVANT II. OBSERVANT II included all consecutive patients with severe aortic stenosis who underwent TAVI across 28 Italian centers from December 2016 to September 2018.

Department of Cardiology, Amsterdam University Medical Center, University of Amsterdam, Amsterdam Cardiovascular Sciences, Amsterdam, the Netherlands. Electronic address:
Background: Transcatheter aortic valve replacement (TAVR) harbors the risk of periprocedural complications that require emergent cardiac surgery, or "surgical bailout." Surgical bailout intends to be lifesaving but is associated with high mortality. This has given rise to discussion on the necessity of surgical backup during TAVR.

Department of Cardiac, Thoracic, Vascular Sciences and Public Health, University of Padua, Padua, Italy.
Background: Lifetime treatment of aortic valve disease is a matter of increasing debate. Although the risks of a second aortic valve intervention are recognized, little attention has been given to the challenges of a third.
Objectives: This study delves into the clinical characteristics, indications, and outcomes of patients undergoing 3 aortic valve interventions.
