The Effect of Aortic Regurgitation on Left Ventricular Flow Dynamics Assessed by 4D-Flow MRI

Author(s): Abdallah W; Darwish A; Garcia J; Kadem L;

Background: Aortic regurgitation (AR) alters normal blood flow patterns in the left ventricle (LV), affecting diastolic filling dynamics, and is commonly quantified by the regurgitant fraction (RF). However, conventional diagnostic methods have notable limitations, prompting growing interest in four-dimensional flow magnetic resonance imaging (4D-flow M ...

On Left Ventricle Stroke Work Efficiency in Children with Moderate Aortic Valve Regurgitation or Moderate Aortic Valve Stenosis

Author(s): Asaadi M; Mawad W; Djebbari A; Keshavardz-Motamed Z; Dahdah N; Kadem L;

The optimal timing for management of pediatric patients with moderate aortic valve disease [moderate aortic stenosis (modAS) or moderate aortic regurgitation (modAR)] remains unknown and largely unexplored. Although usually asymptomatic, the risk of increased left ventricular (LV) wall stress, irreversible myocardial fibrosis and sudden death in untreat ...
