Comparative Efficacy of Antithrombotic Strategies in Bioprosthetic Aortic Valve Replacement: A Network Meta-Analysis.
Angiology
January 2025
Department of Cardiovascular Surgery, Shizuoka Medical Center, Shizuoka, Japan.
This meta-analysis evaluates outcomes in patients undergoing bioprosthetic aortic valve replacement (bAVR), comparing different antithrombotic strategies. We conducted a systematic search through May 2024. A standard meta-analysis compared outcomes between patients who received anticoagulation therapy (AC) and those who did not.
View Article and Find Full Text PDFSevere aortic valve stenosis poses a significant risk for the aging population, often escalating from mild symptoms to life-threatening heart failure and sudden death. Without timely intervention, this condition can lead to disastrous outcomes. The advent of transcatheter aortic valve implantation (TAVI) has gained popularity, emerging as an effective alternative for managing severe aortic stenosis (AS) in high-risk patients experiencing deterioration of previously implanted bioprosthetic surgical aortic valves (SAV), which introduces complex challenges such as device compatibility and anatomical considerations.

Catheter Cardiovasc Interv
January 2025
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.
Impact of Anticoagulation Therapy after Bioprosthetic and Homograft Pulmonary Valve Replacement.
Ann Thorac Surg
January 2025
Department of Cardiac Surgery, Boston Children's Hospital, Boston, MA. Electronic address:
Background: The effect of anticoagulation on early postoperative outcomes following pulmonary valve replacement (PVR) with bioprosthetic valves and homografts is not yet defined. We hypothesized that short-term anticoagulation would be associated with improved valve durability.
Methods: Patients undergoing PVR or right ventricle-pulmonary artery conduits with a bioprosthetic or homograft valve >15 mm in diameter between 1/2015 and 4/2021 at Boston Children's Hospital were retrospectively compared by anticoagulation status.
Incidence and Outcomes of Prosthetic Valve Endocarditis in Adults with Congenital Heart Disease.
Am Heart J
January 2025
Department of Cardiovascular Medicine, Mayo Clinic Rochester, MN 55905. Electronic address:
Background: Patients with congenital heart disease (CHD) often require prosthetic valve implantation, increasing their lifetime risk of developing prosthetic valve endocarditis (PVE). The purpose of this study was to determine the incidence, risk factors, and outcomes of PVE in adults with CHD.
Method: Retrospective cohort study of adults with CHD and prior prosthetic valve implantation (2003-2023).
