BACKGROUND: Major aortopulmonary collateral arteries (MAPCAs) are frequently found in association with pulmonary atresia with ventricular septal defect (PA/VSD). However, some patients with MAPCAs do not have PA/VSD but have a variety of other "atypical" anatomic diagnoses. METHODS: This was a retrospective review of patients with MAPCAs and atypical anatomy. The 50 patients with MAPCAs could be divided into two subgroups: (1) single ventricle anatomy (n = 33) and (2) two ventricle anatomy (n = 17)...

OBJECTIVE: Exercise intolerance afflicts Fontan patients with total cavopulmonary connections (TCPCs) causing a reduction in quality of life. Optimising TCPC design is hypothesised to have a beneficial effect on exercise capacity. This study investigates relationships between TCPC geometries and exercise haemodynamics and performance. METHODS: This study included 47 patients who completed metabolic exercise stress test with cardiac magnetic resonance (CMR). Phase-contrast CMR images were acquired immediately following supine lower limb exercise...

BACKGROUND: Acute kidney injury (AKI) is common following cardiopulmonary bypass. Fontan completion may result in systemic venous hypertension and low cardiac output, reducing renal perfusion pressure (RPP) and further increasing the risk of AKI. We investigated the incidence and risk factors for post-Fontan AKI. METHODS: Single-center retrospective study of children undergoing Fontan completion from 2005 to 2012. Demographic and hemodynamic variables were assessed for association with AKI...

OBJECTIVES: Open heart surgery for interrupted aortic arch in the neonatal period is still a high-risk procedure related in part to patient factors such as low birth weight, other morphologic anomalies, and, especially, small aortic valve size. Recently, we performed hybrid palliation with bilateral pulmonary artery banding and ductal stenting as the first-stage palliation for such cases. In this study, the outcomes of this procedure were examined. METHODS: Six cases of interrupted aortic arch with a small aortic valve underwent the hybrid procedure in the neonatal period in our institute from 2010 to 2015 (mean age: 6...

BACKGROUND: Patient satisfaction with nursing care (NC) is an important predictor of overall satisfaction with the hospital experience. However, the concept of patient satisfaction has been criticised both at the theoretical and at the methodological levels, and more attention on patient dissatisfaction has been called for with the aim of identifying strategies to improve the quality of care. AIMS: To describe dissatisfaction with NC as perceived by acute medical patients and identify predictors...

OBJECTIVE: Limited data exist regarding the outcomes of non-cardiac procedures (NCPs) in adult patients after Fontan operations (Fontan patients). METHODS: To compare procedural outcomes after NCPs in Fontan patients with outcomes for two matched control groups: patients with repaired congenital heart disease and biventricular circulation (CHD-BiV) and patients with no heart disease (NHD). We defined cyanosis as oxygen saturation <90% and procedural hypoxia as saturation <80% or a decrease in saturation >10% from baseline...

Central factors negatively affect the functional capacity of Fontan patients (FP), but "non-cardiac" factors, such as pulmonary function, may contribute to their exercise intolerance. We studied the pulmonary function in asymptomatic FP and its correlations with their functional capacity. Pulmonary function and cardiopulmonary exercise tests were performed in a prospective study of 27 FP and 27 healthy controls (HC). Cardiovascular magnetic resonance was used to evaluate the Fontan circulation. The mean age at tests, the mean age at surgery, and the median follow-up time of FP were 20(±6), 8(±3), and 11(8-17) years, respectively...

We describe a case involving a successful Fontan procedure for the treatment of pulmonary arteriovenous fistulas in a patient with polysplenia. The patient was diagnosed with bilateral superior vena cavae, interrupted inferior vena cava with azygos connection, wide separate hepatic veins, and central pulmonary artery stenosis following repair of a non-confluent pulmonary artery. Bilateral extracardiac conduits were used to connect each hepatic vein to the pulmonary artery, opposite each superior vena cava. Clinical improvement in the pulmonary arteriovenous fistulas was observed within 4 months after surgery...

A controversy exists as to whether de novo-generated neuronal tetraploidy (dnNT) occurs in Alzheimer's disease. In addition, the presence of age-associated dnNT in the normal brain remains unexplored. Here we show that age-associated dnNT occurs in both superficial and deep layers of the cerebral cortex of adult mice, a process that is blocked in the absence of E2F1, a known regulator of cell cycle progression. This blockage correlates with improved cognition despite compromised neurogenesis in the adult hippocampus was confirmed in mice lacking the E2f1 gene...

OBJECTIVES: The capacity and limitations of ventricular assist device (VAD) support in single-ventricle physiology remains poorly understood. We aimed to review our experience in the use of VAD support in the single-ventricle circulation to determine its feasibility in this population. METHODS: We reviewed our experience with VAD support in patients with single ventricles over the past 25 years. Fifty-seven patients received 64 runs of VAD support between 1990 and 2015 at a median age of 13 days [interquartile range (IQR) 4...

Patients after a Fontan operation exhibit some degree of fibrosis which are primarily located in a sinusoidal or centrilobular pattern. Cirrhosis may develop years later and the incidence of cancer is up to 5%. That is why some authors recommend that patients who are >10 years out from their Fontan operation should undergo cardiac assessment as well as the determination of alpha-fetoprotein level, the realization of liver imaging tests or even liver biopsy to stay ahead of neoplastic transformation.

BACKGROUND: Reported long-term outcome measures vary greatly between studies in Fontan patients making comprehensive appraisal of mortality hazard challenging. We sought to create a clinical risk score to assist monitoring of Fontan patients in the outpatient setting. METHODS: A systematic review was conducted to evaluate risk factors for long-term (beyond the first postoperative year) mortality in Fontan patients. Studies were eligible for inclusion if ≥90 patients were included or ≥20 long-term mortalities we reported...

Patients born with a single functional ventricle typically undergo three-staged surgical palliation in the first years of life, with the last stage realizing a cross-like total cavopulmonary connection (TCPC) of superior and inferior vena cavas (SVC and IVC) with both left and right pulmonary arteries, allowing all deoxygenated blood to flow passively back to the lungs (Fontan circulation). Even though within the past decades more patients survive into adulthood, the connection comes at the prize of deficiencies such as chronic systemic venous hypertension and low cardiac output, which ultimately may lead to Fontan failure...

OBJECTIVES: Complex neonatal surgery is considered a risk factor for neuro-developmental impairment in single-ventricle patients. Neuro-developmental outcome was compared between preschool-aged Fontan patients who underwent a Norwood procedure and single-ventricle patients not requiring neonatal surgery with cardiopulmonary bypass. METHODS: Verbal, performance and full-scale intelligence quotient (IQ) were evaluated with the Wechsler Preschool and Primary Scale of Intelligence...

RATIONALE, AIMS AND OBJECTIVES: Errors in hospitals during the preparation and administration of intravenous drugs to infants and children have been reported to a rate of 13% to 84%. This study aimed to investigate the potential for hazardous events that may lead to an accident for preparation and administration of drug injection in a pediatric department and to describe a reduction plan of risks. METHODS: The preliminary hazard analysis (PHA) method was implemented by a multidisciplinary working group over a period of 5 months (April-August 2014) in infants aged from 28 days to 2 years...
