Abstract

Deciding on a surgical pathway for neonates with ≥2 left heart obstructive lesions is complex. Predictors of the successful biventricular (2V) repair in these patients are poorly defined. The goal of our study was to identify patients who underwent the 2V repair and assess anatomic and echocardiographic predictors of success. Infants born between July 2015 and August 2017 with ≥2 left heart obstructive lesions with no prior interventions were identified (n = 19). Patients with aortic or mitral valve (MV) atresia and critical aortic stenosis were excluded. Initial echocardiograms were reviewed for aortic, MV, tricuspid valve annulus size, and left (LV) and right (RV) ventricle diastolic longitudinal dimensions. The valve morphology and presence of a ventricular septal defect (VSD) and coarctation were assessed. Clinical outcomes included successful 2V repair, complications, and repeat interventions or surgeries. Failed 2V repair was defined as a takedown to single ventricle (1V) physiology, cardiac transplantation, or death. For 2V repair, 14/19 patients were selected and for 1V, 5/19 patients were selected. Initial surgical procedures of the 2V group were simple coarctation repair (5), complex coarctation/arch reconstruction +/...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Regulation of Vocal-Motor Plasticity

Dopaminergic projections to the basal ganglia and nucleus accumbens shape the learning and plasticity of motivated behaviors across species including the regulation of vocal-motor plasticity and performance in songbirds. Discover the latest research on the regulation of vocal-motor plasticity here.

Myocardial Stunning

Myocardial stunning is a mechanical dysfunction that persists after reperfusion of previously ischemic tissue in the absence of irreversible damage including myocardial necrosis. Here is the latest research.
