OBJECTIVE Micro-RNAs (miRNAs) are important regulators of gene expression through interaction with the 3'UTR of target messenger RNAs (mRNAs). The role of miRNAs has been extensively studied in adult human and nonhuman animal models of heart disease. Hypoplastic left heart syndrome (HLHS) is the most common form of severe congenital heart disease and is an(More)
BACKGROUND Pediatric heart failure (HF) patients have a suboptimal response to traditional HF medications, although phosphodiesterase-3 inhibition (PDE3i) has been used with greater success than in the adult HF population. We hypothesized that molecular alterations specific to children with HF and HF etiology may affect response to treatment. METHODS AND(More)
Stimulation of the renin-angiotensin-aldosterone system (RAAS) and β-adrenergic receptors plays an important role in adult heart failure (HF). Despite the demonstrated benefits of RAAS inhibition and β-adrenergic receptor blockade in adult HF patients, no substantial improvement in survival rate has been observed in children with HF. This suggests that the(More)
