Multicenter StudyEffects of race, ethnicity, and gender on surgical mortality in hypoplastic left heart syndrome.
Information is limited regarding the effect of race, ethnicity, and gender on the outcomes of the three palliative procedures for hypoplastic left heart syndrome (HLHS). This study examined the effects of race, ethnicity, gender, type of admission, and surgical volume on in-hospital mortality associated with palliative procedures for HLHS between 1998 and 2007 using data from the University HealthSystem Consortium. According to the data, 1,949 patients underwent stage 1 palliation (S1P) with a mortality rate of 29 %, 1,279 patients underwent stage 2 palliations (S2P) with a mortality rate of 5.4 %, and 1,084 patients underwent stage 3 palliation (S3P) with a mortality rate of 4.1 %. ⋯ No racial differences with S3P were observed. The risk factors for increased mortality at S1P were black and "other" race, smaller surgical volume, and early surgical era. The risk factors for increased in-hospital mortality with S2P were black race and Hispanic ethnicity.

Adrenal insufficiency in children undergoing heart surgery does not correlate with more complex postoperative course.
Although some evidence suggests benefit of steroid supplementation after pediatric cardiac surgery, data correlating adrenal function with the postoperative course is scarce. This study sought to determine if adrenal insufficiency (AI) after cardiac surgery is associated with a more complicated postoperative course in children. A prospective study was performed during a 6-month period at a pediatric medical center. ⋯ There were no significant differences between subgroups in inotropic support or urine output during the first 36 h or in mechanical ventilation, sedation, or ICU stay duration. Children with AI after heart surgery do not have a more complex postoperative course than children with NAF. The adrenal response of individual patients seems to be appropriate for their cardiovascular status.

Comparative StudyInterventions after Norwood procedure: comparison of Sano and modified Blalock-Taussig shunt.
Improved results have evolved from the modified Norwood procedure (NP). This study compares the incidence of interventions after NP with the Sano (n = 37) and modified Blalock-Taussig (BT n = 70) shunt. Incidence, location, interval of interventions, and weight were retrospectively analysed for 107 neonates undergoing NP during the period from October 2002 to December 2009. ⋯ Interventions after NP were common irrespective of shunt type. However, a significantly greater rate of shunt interventions was noted in the Sano group. In particular, interventions addressing the aortic arch and the shunt were related with a significant rate of complications.

Case ReportsEfficacy of an interleukin-1β receptor antagonist (anakinra) in idiopathic recurrent pericarditis.
Pericarditis may recur in up to 30 % of adult patients, but recurrent pericarditis is a rare disease in childhood. The etiology of the initial attack and the causes of recurrences often remain unknown. Recurrent pericarditis is accompanied by a high morbidity rate and may represent a challenge to the clinician due to problems in management. ⋯ Controlled trials have demonstrated that colchicine can reduce the recurrent rate of pericarditis, whereas early corticosteroid therapy promotes recurrences. Anakinra, a recombinant human interleukin-1β receptor antagonist, is a promising new biologic agent for the treatment of autoinflammatory diseases such as cryopyrinopathies, tumor necrosis factor receptor-associated periodic syndrome, and hyperimmunoglobulinemia D with periodic fever syndrome. This report describes an 11-year-old boy successfully treated with anakinra for a steroid-dependent recurrent pericarditis unresponsive to conventional treatment.

Case ReportsSuccessful treatment of severe mechanical mitral valve thrombosis with tissue plasminogen activator in a 7-month-old infant.
Severe thrombosis of a mechanical valve is a rare complication in pediatric patients. Thrombolytic therapy as treatment of mechanical mitral valve thrombosis has rarely been reported in young infants. We report the successful treatment with recombinant tissue-type plasminogen activator of a mechanical mitral valve thrombus in a 7 month-old patient with trisomy 21, complete atrioventricular canal defect and pulmonary hypertension status post complete atrioventricular canal repair and subsequent prosthetic mitral valve replacement. ⋯ Serial echocardiograms showed significant resolution of the thrombus within 18 h of infusion with no major bleeding complications during the treatment course. Although a rare complication of mechanical valve placement in pediatrics, thrombosis of mechanical valves may result in severe hemodynamic and respiratory compromise. This case demonstrates that thrombolytic therapy is a feasible option for the treatment of critical thrombosis in pediatric patients after MVR.
