Pulmonary artery banding as adjunct therapy for ventricular recovery after anomalous left coronary artery from the pulmonary artery repair: a case report.

Anomalous left coronary artery from the pulmonary artery is a rare congenital coronary anomaly commonly associated with severe but reversible left ventricular dysfunction. We present an anomalous left coronary artery from the pulmonary artery case of persisting left ventricular failure with inability to wean off the ventilator and inotropes after successful coronary reimplantation, in whom pulmonary artery banding enhanced myocardial recovery.

TIM3+ TRBV11-2 T cells and IFNγ signature in patrolling monocytes and CD16+ NK cells delineate MIS-C.

In rare instances, pediatric SARS-CoV-2 infection results in a novel immunodysregulation syndrome termed multisystem inflammatory syndrome in children (MIS-C). We compared MIS-C immunopathology with severe COVID-19 in adults. MIS-C does not result in pneumocyte damage but is associated with vascular endotheliitis and gastrointestinal epithelial injury.

An Alternative Strategy for Bridge-to-Transplant/Recovery in Small Children with Dilated Cardiomyopathy.

Dilated cardiomyopathy in children still has a poor prognosis with high rates of mortality and cardiac transplantation (resp. around 20 and 25%). Awaiting transplantation or possible recovery, these pediatric patients are mechanically supported with extracorporeal membrane oxygenation or a paracorporeal ventricular assist device, both resulting in higher survival rates but also entailing considerable risks of infection, thrombosis, or bleeding.

Is there a place for intra-aortic balloon counterpulsation support in acute right ventricular failure by pressure-overload?

Background: Most therapeutic strategies for acute right ventricular failure (RVF) by pressure-overload are directed to improve cardiac output and coronary perfusion pressure by vasopressive agents. The eventual role of intra-aortic balloon counterpulsation (IABP) support remains questionable. This study investigates the contribution of IABP for acute RVF by pressure-overload, in comparison with phenylephrine (PE) and norepinephrine (NOR).
