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.

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.
Hemodynamic Valve Deterioration After Transcatheter Aortic Valve Replacement: Incidence, Predictors, and Clinical Outcomes.
JACC Cardiovasc Interv
January 2025
Department of Cardiology, Inselspital, Bern University Hospital, University of Bern, Bern, Switzerland. Electronic address:
Background: Reports on the durability of transcatheter aortic valve replacement (TAVR) prostheses are scarce and confounded by varying definitions and competing risks of death.
Objectives: The authors sought to determine the incidence, predictors, and clinical outcomes of hemodynamic valve deterioration (HVD) according to the Valve Academic Research Consortium 3 definition after TAVR.
Methods: We analyzed consecutive patients undergoing TAVR in the prospective Bern TAVI (Transcatheter Aortic Valve Implantation) registry between August 2007 and June 2022 for the incidence and predictors of HVD and performed case control-matching to compare outcomes according to HVD.
Options for pediatric heart valve replacement.
Future Cardiol

Department of Cardiovascular Surgery, Arkansas Children's Hospital, Little Rock, AR, USA.
Heart valve replacement is indicated for children with irreparable heart valve disease. These replacements come in a variety of forms including mechanical, xenograft tissue, allograft tissue, and autograft tissue valves. These options each have unique benefits and risks profiles.

Valvular heart disease (VHD) poses a significant threat to human health, and the transcatheter heart valve replacement (THVR) is the best treatment for severe VHD. Currently, the glutaraldehyde cross-linked commercial bioprosthetic heart valves (BHVs) remain the first choice for THVR. However, the cross-linking by glutaraldehyde exhibits several drawbacks, including calcification, inflammatory reactions, and difficult endothelialization, which limits the longevity and applicability of BHVs.
