Key result

Cardiac CT and MRI serve as key multimodality imaging techniques for evaluating paravalvular leaks.

Key Points

To review and define the clinical utility of multimodality imaging, specifically cardiac computed tomography and magnetic resonance imaging, in identifying and managing paravalvular leaks.
Evaluation of cardiac computed tomography (CT) protocols for high-resolution anatomical assessment of prosthetic valve dehiscence.
Evaluation of cardiac magnetic resonance imaging (MRI) protocols for hemodynamic assessment and quantification of regurgitant fraction.
Cardiac CT provides detailed three-dimensional visualization of prosthetic valve anatomy, accurately delineating defect size, location, and adjacent structures for percutaneous closure planning.
Cardiac MRI provides accurate, noninvasive quantification of paravalvular regurgitant volume and secondary ventricular remodeling without acoustic shadowing limitations.

Answers are grounded in this paper and cite their sources.

May inform noninvasive paravalvular leak evaluation; leaves open prospective validation of optimal protocols.
