Core Laboratory Versus Center-Reported Echocardiographic Assessment of the Native and Bioprosthetic Aortic Valve.
Echocardiography
December 2024
Cardiovascular Core Laboratories, MedStar Health Research Institute, and Georgetown University, Washington, District of Columbia, USA.
Article Synopsis
- The study examined differences in echocardiographic assessments of native and bioprosthetic aortic valves between core laboratories and clinical centers, finding clinically relevant discrepancies.
- Data was collected from the PERIGON trial, which involved patients undergoing surgical aortic valve replacement, and involved comparing echocardiographic results from centers to independent analysis by a core lab.
- Results showed that while some continuous measurements had high agreement (around 0.90), there were notable variances, particularly in left ventricular outflow tract area and stroke volume, indicating the need for standardized evaluation practices.
Step-by-Step Transcatheter Tricuspid Valve Replacement Using the LuX-Valve Plus System.
JACC Case Rep

Division of Cardiology, Department of Medicine and Therapeutics, Prince of Wales Hospital, Chinese University of Hong Kong, Hong Kong, China.
The LuX-Valve Plus is a novel radial force-independent orthotopic transjugular transcatheter tricuspid valve replacement device proven to be effective in TR reduction. We describe preprocedural assessment for eligibility and procedural planning by means of computed tomography as well as procedural steps of device implantation under multimodality imaging guidance including transesophageal echocardiography (TEE), intracardiac echocardiography (ICE), and fluoroscopy: steering into the right ventricle, leaflet capture by graspers, fine valve adjustment, and septal anchor deployment. Potential pitfalls are avoided by achieving optimal alignment by means of TEE multiplanar reconstruction to steer the delivery system, and using mid-esophageal and deep gastric views of 3-dimensional TEE and supplementary ICE to visualize the graspers for leaflet capture, especially when TEE imaging is technically challenging.

J Clin Med
November 2024
Cardiovascular Research Institute, CARIM, 6629 ER Maastricht, The Netherlands.
Article Synopsis
- Aortic valve replacement (AVR) has seen an increased use of the Perceval sutureless bioprosthesis, which shows promising safety and reliability in both short- and mid-term outcomes, with some long-term data emerging.
- An updated systematic review of studies from 2015 to 2024 analyzed long-term outcomes of 5,221 patients with Perceval implants, revealing a long-term survival rate between 64.8% to 87.9% and low rates of complications such as structural valve degeneration and significant leaks.
- Despite limited data on sutureless bioprostheses, the encouraging results from existing studies suggest that Perceval could provide
Whether monitored anesthesia care is the optimal anesthetic strategy for transcatheter aortic valve implantation surgery? a meta-analysis and systematic review.
BMC Anesthesiol
November 2024
Department of Anesthesia and Surgery, First Hospital of Lanzhou University, Lanzhou, 730000, Gansu, China.
Objectives: To explore whether monitored anesthesia care is more beneficial to the outcome of transcatheter aortic valve implantation.
Methods: The research methodology involved comprehensive searches across major databases, including the Cochrane Library, PubMed, Scopus, and Web of Science, covering the period from January 1, 2010, to March 1, 2024. The aim was to identify trials comparing different anesthetic methods for transcatheter aortic valve implantation.
Clinical Outcomes of Transcatheter Mitral Valve-In-Valve and Valve-In-Ring Implantation: A Systematic Review and Meta-Analysis.
Catheter Cardiovasc Interv
January 2025
Department of Cardiology, National Heart Centre Singapore, Singapore, Singapore.
Article Synopsis
- Transcatheter valve-in-valve (VIV) and valve-in-ring (VIR) therapies for failing mitral bioprosthetic valves are being researched to understand their effectiveness and safety over time.
- A meta-analysis reviewed 34 studies involving 7,047 patients to assess short and long-term outcomes, focusing on complications like mortality, stroke, and procedural success rates.
- Findings indicated high success rates of 94.8% for VIV and 80.5% for VIR, with varying short-term mortality and stroke risks across VIV, VIR, and traditional redo surgical mitral valve replacements (SMVR).
