Sonic Hedgehog (Shh), encoding an extracellular signaling molecule, is vital for heart development. Shh null mutants show congenital heart disease due to left-right asymmetry defects stemming from functional anomaly in the midline structure in mice. Shh signaling is also known to affect cardiomyocyte differentiation, endocardium development, and heart morphogenesis, particularly in second heart field (SHF) cardiac progenitor cells that contribute to the right ventricle, outflow tract, and parts of the atrium.

Because these patients are living longer, treatment and disease surveillance targets have shifted toward enhancing quality of life and functional status. Cardiopulmonary exercise testing is a valuable tool for assessing functional capacity, evaluating cardiac and pulmonary pathology, and providing guidance on prognosis and interventional recommendations.

Background: The United Network of Organ Sharing made changes to the priority for allocation of hearts for transplantation (HT) in 2016 for pediatric patients and 2018 for adult patients. Although recent work has evaluated the impact of the revised allocation systems on mechanical circulatory support practices and waitlist outcomes, there are limited data that focus more specifically on the impact of the allocation changes on patients with congenital heart disease (CHD) or cardiomyopathy and how these relationships might differ in pediatric and adult patients.
Methods: The United Network of Organ Sharing database was queried for pediatric (<18 years of age) and adult (18-50 years of age) patients with a CHD or cardiomyopathy diagnosis listed for HT.

Heart valve replacement is indicated for children with irreparable heart valve disease. These replacements come in a variety of forms including mechanical, xenograft tissue, allograft tissue, and autograft tissue valves. These options each have unique benefits and risks profiles.

A multitude of studies have presented inconsistent outcomes regarding the association between maternal folic acid (FA) and/or multivitamin (MV) supplementation and congenital heart disease (CHD) in offspring. This study aimed to estimate supplementation time and CHD based on a prospective China birth cohort study (CBCS). In the CBCS, 114,670 singleton pregnant women who had pregnancy outcomes until August 2021 and responded to the early pregnancy questionnaire were recruited.
