Comparative StudyLeft Atrial Phasic Function by Cardiac Magnetic Resonance Feature Tracking Is a Strong Predictor of Incident Cardiovascular Events.
The prognostic importance of left atrial (LA) dysfunction is increasingly recognized. Magnetic resonance imaging can provide excellent visualization of the LA wall. We aimed to study the association of LA dysfunction measured using feature-tracking magnetic resonance imaging with incident adverse cardiovascular events among subjects with or without heart failure (HF) at baseline. ⋯ Phasic LA function measured using magnetic resonance imaging feature tracking is independently predictive of the risk of incident HF admission or death, even after adjusting for LA volume and left ventricular remodeling.

Aortic Root Dilatation and Aortic-Related Complications in Children After Tetralogy of Fallot Repair.
The study objective was to assess the severity, progression rate, and risk factors for aortic root dilatation (ARD) in pediatric tetralogy of Fallot (TOF) and to study its relationship to complications including aortic regurgitation. ⋯ ARD is common before and after TOF repair, but our data suggest that aortic root dimensions remain stable in the majority of pediatric TOF patients. Progressive ARD and aortic-related complications are distinctly uncommon during childhood.
