Variation in Recovery of Myocardial Strain in Infants with Coarctation Who Present with Left Ventricular Dysfunction

Background: Infants with delayed diagnosis of aortic coarctation who present with left ventricular (LV) dysfunction are typically treated with heart failure medications until their LV ejection fraction (EF) normalizes. LV strain is a measure of ventricular function that has been shown to be more reproducible than EF and to correlate with clinical outcomes in many patient populations. We aimed to determine the evolution …
