Photon-counting detector CT for prediction of valve dysfunction after transcatheter aortic valve implantation: Comparison with echocardiography.

BACKGROUND Noninvasive evaluation of suspected prosthetic valve dysfunction after transcatheter aortic valve implantation (TAVI) remains challenging because both anatomic and hemodynamic information are required for a conclusive diagnosis. PURPOSE To evaluate the diagnostic accuracy of hemodynamic parameters derived...

Adverse Remodeling and Fibrosis Predict Outcomes in Excessive Trabeculation of the Left Ventricle: A Multiparametric CMR Risk Score.

BACKGROUND Excessive trabeculation of the left ventricle (ETLV) is a heterogeneous and controversial phenotype that overlaps with both physiological remodeling and cardiomyopathy. OBJECTIVES This study sought to develop and validate a cardiac magnetic resonance (CMR)-based model to predict major adverse cardiovascula...
