Long-Term Bioprosthetic Valve Durability After Transcatheter Aortic Valve Replacement With Supra-Annular Self-Expanding Versus Intra-Annular Balloon-Expandable Valves in Patients With a Small Aortic Annulus.
Catheter Cardiovasc Interv

Department of Cardiovascular Medicine, Osaka University Graduate School of Medicine, Osaka, Japan.
Background: The long-term valve durability of supra-annular self-expanding valves (SEV) and intra-annular balloon-expandable valves (BEV) in patients with small aortic annuli remains unexplored.
Aims: This study aimed to determine the long-term bioprosthetic valve durability with SEV versus BEV in patients with small aortic annuli.
Methods: This retrospective study included patients with severe aortic stenosis (AS) and an aortic annulus area of 430 mm or less who underwent transcatheter aortic valve replacement using SEV and BEV between October 2009 and December 2022.
Valve Frame Geometry and Arrhythmia Risk Following Self-Expanding Transcatheter Pulmonary Valve Replacement.
Pediatr Cardiol

School of Medicine, Children's Hospital Colorado, The Heart Institute, University of Colorado Denver|Anschutz Medical Campus, 13123 E 16Th Ave, Box 100, Aurora, CO, 80045-2560, USA.
Though major complications during transcutaneous pulmonary valve replacement (TPVR) are rare, clinically-significant ventricular arrythmia (CSVA) has been reported following self-expanding valve placement. We assess whether alterations in valve frame dimensions and geometry within the right ventricular outflow tract (RVOT) post-implantation in patients who underwent TPVR with Harmony TPV25 or Alterra contribute to CSVA risk. A single center review was performed of patients who underwent TPVR with either Harmony TPV25 or Alterra Pre-stent between August 2019 and April 2023.

J Thorac Cardiovasc Surg
January 2025
Department of Surgery, Division of Vascular Surgery, University of Maryland School of Medicine.
Objective: We present our experience with endovascular Bentall procedure (Endo-Bentall) using a modular valve conduit (Endo-Bentall) in high-risk patients with aortic root pathologies.
Methods: The physician constructed Endo-Bentall device is composed of a self-expanding transcatheter aortic valve (TAVR), aortic endovascular stent graft (TEVAR), and two wire-reinforced fenestrations for coronary artery stenting. The TAVR valve is sutured into an appropriately sized TEVAR graft.
From Zone -1 to Zone 3: Feasibility and Safety of Complex Endovascular Aortic Repairs in Type A Aortic Dissection.
J Thorac Cardiovasc Surg
January 2025
University of Maryland School of Medicine, Division of Cardiothoracic Surgery. Electronic address:
Objective: Over 30% of patients presenting with acute type A aortic dissection (ATAAD) are considered high - risk or inoperable. This study aims to investigate the early and mid-term outcomes of complex endovascular aortic repair of aortic root, ascending aorta, and aortic arch among patients with ATAAD.
Methods: From January 2018 to January 2023, 29 patients who were considered high risk for open operation underwent endovascular aortic repair.
Initial Multicenter Experience With a Novel Self-Expanding TAVR System in Patients With Aortic Valve Stenosis.
JACC Cardiovasc Interv
January 2025
Clinic for General and Interventional Cardiology/Angiology, Herz- und Diabeteszentrum NRW, Ruhr-Universität Bochum, Bad Oeynhausen, Germany. Electronic address:
Background: As transcatheter aortic valve replacement is performed increasingly in younger, low-risk patients, the need for commissural alignment and coronary access has increased. Design elements of the JenaValve Trilogy (JVT) transcatheter heart valve (THV) ensure both.
Objectives: This study sought to evaluate the outcome of patients with aortic stenosis (AS) treated with this novel transfemoral, self-expanding THV.
