BACKGROUND: The purpose of the study was to determine the role of cardiopulmonary exercise test (CPET) indices in predicting cardiovascular adverse events (CAEs) in patients with Fontan palliation. CAE was defined as death or cardiac surgery. METHODS: Retrospective review of adult Fontan patients who had treadmill CPET at Mayo Clinic, 1994-2013. Patients with loss of follow-up defined as ≥2years without clinical follow-up were excluded. The results of serial CPETs were reviewed, and patients with CPETs meeting the following criteria were selected for analysis: maximum effort on serial CPETs, minimum of 3-year interval between CPETs, and absence of CAE between CPETs...

BACKGROUND: Fontan survivors have depressed cardiac index that worsens over time. Serum biomarker measurement is minimally invasive, rapid, widely available, and may be useful for serial monitoring. The purpose of this study was to identify biomarkers that correlate with lower cardiac index in Fontan patients. Methods and results This study was a multi-centre case series assessing the correlations between biomarkers and cardiac magnetic resonance-derived cardiac index in Fontan patients ⩾6 years of age with biochemical and haematopoietic biomarkers obtained ±12 months from cardiac magnetic resonance...

Among the most significant factors affecting quality of life in individuals with critical congenital heart disease (CCHD) are neurodevelopmental challenges, including deficits in visuospatial processing and academic achievement. Few studies have compared outcomes across CCHD subgroups, despite their significant differences in anatomy/physiology and medical/surgical courses. This study compared visuospatial processing abilities using the Developmental Scoring System for the Rey-Osterrieth Complex Figure (DSS-ROCF) across groups of adolescents with CCHD (d-transposition of the great arteries [TGA, n = 139], Tetralogy of Fallot [TOF, n = 68], single-ventricle cardiac anatomy requiring the Fontan operation [SVF, n = 145]) and a group of healthy controls (CTR, n = 111), and examined the validity of visuospatial processing in predicting concurrent academic outcomes...

Current studies on the incidence of arrhythmias after the intra-atrial lateral tunnel (ILT) Fontan operation and the extra-cardiac conduit (ECC) Fontan operation are limited, with controversial results. This systematic review aimed to compare the prevalence of arrhythmias in patients who underwent ECC or ILT Fontan. Relevant studies comparing the incidence of arrhythmias and pacemaker implantation in ILT with ECC were identified through a literature search using MEDLINE, EMBASE, and the cochrane central register of controlled trials...

BACKGROUND: The polytetrafluoroethylene tube used as right ventricle to pulmonary artery conduit in the stage 1 Norwood operation is associated with risks of suboptimal branch pulmonary artery growth, thrombosis, free insufficiency, and long-term right ventricular dysfunction. Our experience with use of valved femoral vein homograft as right ventricle to pulmonary artery conduit is described. METHODS: Between June 2012 and December 2015, 15 neonates with hypoplastic left heart syndrome or complex single ventricle underwent stage 1 Norwood operation with valved segment of femoral vein homograft as right ventricle to pulmonary artery conduit...

It has been demonstrated that hepatic apparent diffusion coefficients (ADC) are decreasing in patients with a Fontan circulation. It remains however unclear whether this is a true decrease of molecular diffusion, or rather reflects decreased microperfusion due to decreased portal blood flow. The purpose of this study was therefore to differentiate diffusion and microperfusion using intravoxel incoherent motion (IVIM) modeled diffusion-weighted imaging (DWI) for different liver segments in patients with a Fontan circulation, compare to a control group, and relate with liver function, chronic hepatic congestion and hepatic disease...

Research on emerging substances in drinking water presents major interest and the possibility of trace contamination has seen increasing concern from the scientific community and the public authorities. More particularly, residues of pharmaceuticals and personal care products (PPCPs) in bottled water are a very important issue due to societal concerns and potential media impact. In this context, it has become necessary to carry out reliable monitoring. This requires measurements of high quality with demonstration of accuracy and well-defined uncertainty...

BACKGROUND: Fontan conversion from a classic Fontan operation such as atriopulmonary connection to total cavopulmonary connection with antiarrhythmia surgery is currently not indicated for patients without any late Fontan complications. METHODS: Thirty-two consecutive patients who underwent Fontan conversion between 1991 and 2012 were divided into 2 groups by the presence (group 1: n = 25, atrial tachyarrhythmia [AT] in 24 and protein-losing enteropathy in 4) or absence (group 2: n = 7) of late Fontan complications, and the surgical outcomes were retrospectively compared...

The goal of the study was to compare the early postoperative course after fenestrated lateral atrial tunnel (LT) and non-fenestrated extracardiac conduit (EC) Fontan operation (FO) in a single center where both techniques were parallelly used. Between 2004 and 2012, 56(32.7%) children underwent LT and 113(66.1%) EC FO. The mean age was 3.7 ± 2.9 years and mean weight was 14.6 ± 7.3 kg. The most common malformation was hypoplastic left heart syndrome (50.9%). The general approach was to perform LT in children after hemi-Fontan operation and EC in patients after Glenn anastomosis...

Myocardial dysfunction and heart failure are common in pediatric patients with congenital and acquired heart disease. Alkaline phosphatase (AP) has been suggested as a biomarker for myocardial dysfunction after Fontan operation. We hypothesized that pediatric patients with myocardial dysfunction requiring orthotopic heart transplant (OHT) have diminished AP compared to normal. A retrospective review was performed in all patients who underwent OHT at Arkansas Children's Hospital between January 2007 and October 2012...

Several surgical approaches for completion of a total cavopulmonary connection have been established for patients with anomalies of systemic venous connection in association with a functionally univentricular heart. We report an alternative technique designed to address the problem of widely separated inferior systemic veins, in which two extracardiac conduits were used. This technique was performed on three patients and yielded excellent short-term results, allowing us to operate on a beating heart with no need for cardioplegic arrest and aortic cross-clamping...

BACKGROUND: We compared brain cortical and subcortical gray matter volumes and cortical thickness between post-Fontan patients and healthy controls, and examined brain anatomical associations with operative and medical history characteristics. METHODS: Post-Fontan (n = 128 volumes; n = 115 thickness) and control subjects (n = 48 volumes; n = 45 thickness) underwent brain MRI at ages 10-19 years. Subcortical and cortical volumes and cortical thicknesses were measured for intergroup comparison...

BACKGROUND: The Fontan palliation is associated with numerous complications during long-term. The Fontan conversion operation has been advocated as an option to avoid some of these problems by converting classical Fontan types to modern forms of the circulation. Early mortality of Fontan conversion, however, remains unclear as available reports include limited numbers of patients and the results are heterogeneous. METHODS: We reviewed all original articles from 1994 to 2016 reporting Fontan conversion operations...

The left superior vena cava became occluded in an infant with hypoplastic left heart syndrome. After a bidirectional Glenn procedure, he presented with severe oxygen desaturation and right ventricular dysfunction; the left superior vena cava drained into the inferior vena cava through collateral veins. As salvage therapy, we created a modified total cavopulmonary shunt using only autologous tissue in which the right hepatic vein and inferior vena cava drained into the pulmonary artery via a lateral tunnel in the right atrium...

Although fenestration is used to improve the postoperative course of Fontan patients, the effect of fenestration on the extracardiac Fontan seems controversial especially at early postoperation. One hundred and eighty-three patients from January 2004 to June 2013 undergoing an extracardiac Fontan operation were retrospectively selected for this study. We divided the patients into low risk (93 patients) and high risk (90 patients) groups according to the risk factors recognized by previous studies and then compared the perioperative data between the nonfenestrated and fenestrated patients in each group...

The pathophysiology of congenital heart disease includes aortic dilation and increased stiffness. However, the clinical determinants and significance remain unclear in patients after the Fontan operation.Size and stiffness index (SI) of the ascending and descending aorta (aAO and dAO, respectively) were assessed using angiography in 130 consecutive Fontan patients and 30 age-matched controls. Compared with controls, Fontan patients showed a dilated aAO and smaller dAO (P < 0.0001) with greater SI (3.2 ± 0...
