This updated Heart Valve Collaboratory framework addresses the growing concern for transcatheter valve failure (TVF) following transcatheter aortic valve replacement (TAVR). With the increasing volume of redo-TAV and surgical TAV explantation, there is a critical need for standardized pathways and protocols for evaluating TVF using echocardiography and cardiac computed tomography (CT) angiography. This document clarifies prior definitions of bioprosthetic valve deterioration and bioprosthetic valve failure in a practical, imaging directed context for TAVR.

Background: The use of transcatheter aortic valve implantation (TAVI) for severe aortic stenosis is expanding to patients across the entire spectrum of surgical risk. We aimed to perform a meta-analysis comparing TAVI and surgical aortic valve replacement (SAVR) in trials enrolling lower risk patients.
Methods: We conducted a meta-analysis of randomized controlled trials (RCTs) comparing safety and efficacy outcomes between TAVI and SAVR among lower risk patients (mean/median STS score <4).

Background: Transcatheter Aortic Valve Implantation (TAVI) has become the routine standard of care in patients with severe aortic stenosis and prohibitive surgical risk worldwide. However, data on TAVI outcomes from Africa remain sparse. This study aimed to evaluate the outcomes of TAVI in Africa.

Background: Due to the presence of complex flow states and significant jet eccentricity in patients with congenital heart disease (CHD), accurate quantification of aortic regurgitation (AR) using standard echocardiographic or conventional cardiac magnetic resonance (CMR) imaging measures remains challenging. Four-dimensional flow (4DF) CMR permits transvalvular flow quantification under non-laminar flow states, although has not been well validated for AR quantification in CHD.
Methods: In 186 patients with moderate or complex CHD, we evaluated the agreement between different methods of AR quantification by 4DF CMR when compared to volumetry.

Background: Despite the widespread adoption of selective antegrade cerebral perfusion (SACP) for neonatal aortic arch reconstruction, significant variability in techniques persists across institutions, reflecting limited supporting data and lack of consensus on best practices. This review aims to comprehensively characterize the utilization of SACP in the extant literature and highlight variation in practice to guide future research and standardization of care.
Methods: A comprehensive search was conducted using Embase, Medline/OVID, and NCBI/PubMed databases to identify studies published from 1999-2024 that contained the following terms: ('neonatal' OR 'neonate' OR 'newborn') AND ('aortic arch' OR 'Norwood' OR 'stage one') AND ('circulatory arrest' OR 'cerebral perfusion').
