Multidetector computed tomography is an essential tool for evaluating the aortic root and annulus prior to TAVI, providing highly reproducible measurements that help reduce paravalvular regurgitation.
Does multidetector computed tomography for preprocedural planning improve annular sizing and reduce paravalvular regurgitation in patients undergoing TAVI?
MDCT is an essential tool for pre-TAVI evaluation, providing highly reproducible annular measurements that guide valve selection and reduce the risk of paravalvular regurgitation.
PURPOSE OF REVIEW: Advancements in the use of multidetector computed tomography (CT) in transcatheter aortic valve implantation/transcatheter aortic valve replacement (TAVI/TAVR) over the last year reaffirm its role in the evaluation of preprocedural planning and procedural guidance. The purpose of this review is to provide an up-to-date review of recently published data, with a particular focus on annular sizing and transcatheter heart valve selection to help reduce paravalvular regurgitation. RECENT FINDINGS: Recent data have confirmed that multidetector computed tomography (MDCT) measures of the annulus are highly reproducible across multiple readers and workstation platforms. MDCT has also been shown to have a strong discriminatory ability to predict and reduce postprocedural paravalvular regurgitation (PAR), as well as presenting the current data for integrating CT measures of the annulus into sizing. SUMMARY: Over the last year, MDCT has solidified itself as an essential tool for the evaluation of the aortic root and annulus prior to TAVI. MDCT annular measurements are highly reproducible and now form the basis for transcatheter heart valve selection, with early data suggesting that CT integration can reduce paravalvular regurgitation.
Nguyen et al. (Fri,) conducted a review in Patients prior to transcatheter aortic valve implantation (TAVI/TAVR). Multidetector computed tomography (MDCT) was evaluated. Multidetector computed tomography is an essential tool for evaluating the aortic root and annulus prior to TAVI, providing highly reproducible measurements that help reduce paravalvular regurgitation.
