Cardiac magnetic resonance markers of progressive RV dilation and dysfunction after tetralogy of Fallot repair.

Objective: Patients with repaired tetralogy of Fallot (TOF) are followed serially by cardiac magnetic resonance (CMR) for surveillance of RV dilation and dysfunction. We sought to define the prevalence of progressive RV disease and the optimal time interval between CMR evaluations.

Methods: Candidates were selected from a multicentre TOF registry and were included if ≥2 CMR studies performed ≥6 months apart were available without interval cardiovascular interventions.

Safety of Magnetic Resonance Imaging After Implantation of Stainless Steel Embolization Coils.

Stainless steel embolization coils (SSEC) have been used for over four decades for vascular occlusion. Recently, the safety of these coils in a magnetic resonance environment has been called into question, with important ramifications for thousands of patients with existing coils in place. We performed a retrospective chart review at five tertiary care pediatric centers evaluating all children and young adults with implanted SSEC who underwent magnetic resonance imaging (MRI).

An expectancy-value model of emotion regulation: implications for motivation, emotional experience, and decision making.

According to expectancy-value models of self-regulation, people are motivated to act in ways they expect to be useful to them. For instance, people are motivated to run when they believe running is useful, even when they have nothing to run away from. Similarly, we propose an expectancy-value model of emotion regulation, according to which people are motivated to emote in ways they expect to be useful to them, regardless of immediate contextual demands.

Contemporary predictors of death and sustained ventricular tachycardia in patients with repaired tetralogy of Fallot enrolled in the INDICATOR cohort.

Objective: Patients with repaired tetralogy of Fallot (TOF) experience increased rates of mortality and morbidity in adulthood. This study was designed to identify risk factors for death and ventricular tachycardia (VT) in a large contemporary cohort of patients with repaired TOF.

Methods: Subjects with repaired TOF from four large congenital heart centres in the USA, Canada and Europe were enrolled.

The effects of pregnancy on right ventricular remodeling in women with repaired tetralogy of Fallot.

Objectives: The aim of this study was to better understand the quantitative volumetric changes associated with pregnancy in women with repaired tetralogy of Fallot (TOF), utilizing sequential cardiovascular magnetic resonance (CMR) imaging.

Background: An increasing number of women with repaired TOF are reaching childbearing age. Limited echocardiographic studies suggest accelerated remodeling of the right ventricle (RV) in women with repaired TOF after pregnancy.
