Outcomes of hypoplastic left heart syndrome in low-birth-weight patients.
The objective of this study was to assess outcomes of hypoplastic left heart syndrome (HLHS) patients weighing ≤ 2.5 kg throughout staged palliation. We performed a single-center retrospective review. Abstracted data included gestational age, birth weight, presence of noncardiac anomalies, and survival through Fontan. ⋯ Overall survival for palliated patients from birth through Fontan was 36%. Low-birth-weight neonates with HLHS have poor overall survival through the Fontan operation, with highest mortality following Stage 1 palliation. Being small for GA and the presence of noncardiac anomalies are important preoperative risk factors for early mortality.

Case ReportsAutologous right pulmonary artery tissue for repair of left pulmonary artery originating from left patent ductus arteriosus in a patient with tetralogy of Fallot and absent pulmonary valve.
Left pulmonary artery (PA) originating from patent ductus arteriosus is an exceptionally rare variant of tetralogy of Fallot with absent pulmonary valve. We described an alternative technique for the repair of discontinuous left PA with the use of the redundant pulmonary artery tissue as material for the conduit in a 3-year-old boy.

Randomized Controlled Trial Comparative StudyProtective effect of propofol and its relation to postoperation recovery in children undergoing cardiac surgery with cardiopulmonary bypass.
The aim of this study was to investigate the effect of propofol and its relation to postoperation recovery in children undergoing cardiac surgery with cardiopulmonary bypass (CPB). Twenty ASA class I-II children with congenital heart disease undergoing cardiac surgery were randomly allocated to a propofol group (n = 10) or a control group (n = 10). Blood samples were collected at five time points: before operation (T (0)), before the start of CPB (T (1)), 25 min after the aorta was cross-clamped (T (2)), 30 min after release of the aortic cross-clamp (T (3)), and 2 h after the cessation of CPB (T (4)). ⋯ In addition, propofol inhibited the increase of myocardial nuclear factor-κB (NF-κB) expression and inflammatory cells infiltration after CPB. Furthermore, propofol significantly shortened the tracheal extubation time. In conclusion, propofol exerts a protective effect and improves postoperation recovery through its antioxidant and anti-inflammatory actions in children undergoing cardiac surgery with CPB.

Comparative StudyShort-term outcomes of acute fulminant myocarditis in children.
Data on the clinical profile, echocardiographic findings, and outcome of acute fulminant myocarditis (AFM) in children from resource limited countries are limited. To study the clinical profile and short-term outcomes of children aged 2 months to 17 years with AFM managed with only supportive care. We enrolled all children admitted with AFM in our hospital from January 2009 to October 2010. ⋯ One child had died at 2-month follow-up, and another child developed dilated cardiomyopathy at 15 months after discharge. Children with AFM had good immediate- and short-term outcomes even without the use of mechanical assist devices. Decreased LVEF at admission was found to be one of the most important determinants of poor immediate outcomes in these children.
