Increasing habitual exercise has been associated with improved cardiopulmonary exercise testing (CPET) performance, specifically maximal oxygen consumption in children with operatively corrected congenital heart disease. This has not been studied in children following Fontan palliation, a population in whom CPET performance is dramatically diminished. A single-center cross-sectional study with prospective and retrospective data collection was performed that assessed habitual exercise preceding a clinically indicated CPET in children and adolescents with Fontan palliation, transposition of the great arteries following arterial switch operation (TGA), and normal cardiac anatomy without prior operation...

Congenital heart disease accounts for 40% of pediatric heart transplants and presents unique challenges to the transplant team. Suitability for transplantation is defined in part by degree of sensitization, pulmonary vascular resistance, and hepatic reserves. The incremental transplant risk for patients with congenital heart disease occurs within the first 3 months, after which survival is equivalent to transplantation for cardiomyopathy. Single ventricle with prior palliation, and especially the failing Fontan, carry the highest risk for transplantation and are least amenable to bridging with mechanical circulatory support...

BACKGROUND: Aerobic capacity (VO2 max) of patients with Fontan circulation (FC) is lowest within patients with congenital heart disease. The reasons have not been completely elucidated. METHODS: Twenty five young patients with non-failing FC underwent a cardiopulmonary test during an upright ramp cycling. By using a signal morphology impedance cardiography device (physioflow®), stroke volume (SV) was evaluated along with effort. The results were compared with paired healthy controls...

Failing Fontan physiology in univentricular hearts manifest with protein-losing enteropathy, plastic bronchitis, low cardiac output, and recurrent effusions. Transcatheter creation of fenestration in a failing Fontan may be useful in alleviating the symptoms by improving the cardiac output. It is traditionally achieved by puncturing through the conduit from femoral or jugular venous access. In the absence of good venous path, transhepatic access provides a direct route for needle puncture of the conduit. If marked intimal ingrowth into the conduit results in increasing rigidity and makes the conduit nonyielding, alternative approaches may be needed...

We report multi-organ histopathological changes in a patient with protein-losing enteropathy (PLE) over 12 years after Fontan operation. A 14-year-old boy with right isomerism heart and single ventricle had undergone Fontan procedure at 19 months of age, and PLE was diagnosed at 28 months. He had several episodes of intestinal bleeding and pre-renal failure with elevated creatine, and eventually died of pneumonia. The intrapulmonary small arteries showed medial and intimal thickening resembling pulmonary hypertension...

Six months after undergoing a Fontan operation, a 7-year-old boy with right atrial isomerism and a single functional ventricle was admitted to our emergency department with cyanosis. Emergency cardiac catheterization revealed a large veno-venous fistula that began in a left hepatic vein, connected to the left accessory hepatic veins, and drained into the common atrium, resulting in desaturation. The fistula was occluded proximally with an Amplatzer septal occluder, with satisfying results; the patient's systemic arterial saturation decreased during his hospital stay...

BACKGROUND: Combined heart and liver transplantation (CHLT) in the pediatric population involves a complex group of patients, many of whom have palliated congenital heart disease (CHD) involving single ventricle physiology. OBJECTIVE: The purpose of this study was to describe the perioperative management of pediatric patients undergoing CHLT at a single institution and to identify management strategies that may be used to optimize perioperative care. METHODS: We did a retrospective database review of all patients receiving CHLT at a children's hospital between 2006 and 2014...

OBJECTIVES: Adults with failing Fontan circulation (FFC) represent a heterogeneous, high-risk group for cardiac transplantation with poor reported outcomes. We studied the impact of mode of Fontan failure (preserved versus impaired systolic ventricular function) and end-organ dysfunction on early survival in adults undergoing cardiac transplantation for FFC. METHODS: A single-centre, retrospective study of 26 adults (≥16 years) with FFC undergoing cardiac transplantation between 1990 and 2015...

We performed a retrospective review of outcomes after heart transplantation during long-term follow-up of a surgical cohort of 1138 Fontan patients who were followed at the Mayo Clinic. Follow-up information was obtained from medical records and a clinical questionnaire that was mailed to patients not known to be deceased at the initiation of the study. Forty-four of 1138 Fontan patients with initial or subsequent evaluation at Mayo had cardiac transplantation between 1988 and 2014 (mean age at transplantation was 23...

BACKGROUND: To determine if Fontan conversion (FC) resulted in improvement in exercise capacity (EC), and to determine the role of cardiopulmonary exercise test (CPET) in risk stratification of patients undergoing FC. METHODS: A retrospective review of patients who underwent CPET prior to FC at Mayo Clinic from 1994 to 2014. The patients who also underwent post-operative CPET were selected for the analysis of improvement in EC defined as 10% increase in baseline peak oxygen consumption (VO2)...

An infrequent but devastating late complication of Fontan circulation is protein-losing enteropathy (PLE), which results from unbalanced lymphatic homeostasis. Surgical decompression of the thoracic duct by redirecting its drainage to the pulmonary venous atrium has been introduced recently as a possible treatment. This report describes a single-institution experience with this innovative procedure in 2 patients with failing Fontan circulation with PLE refractory to optimized medical therapy.

A 28-year-old male with single ventricular heart disease status post Fontan palliation and subsequent placement of left ventricle to ascending aorta (LV-AAo) valved conduit developed ascites and edema. Diagnostic catheterization revealed elevated ventricular end diastolic pressures (EDP) secondary to severe LV-AAo conduit regurgitation. Given the unique anatomy, surgical access via the right axillary artery provided optimal route for transcatheter valve implantation within the conduit. The procedure resulted in significant hemodynamic improvement with no complications...

While policy changes toward early extubation in the operating room (OR) have been commonly seen in palliative surgeries in single ventricle anatomy, no systematic assessment of their impact on patient outcome has been reported. All patients aged 0-17 years admitted to a PICU in a quaternary children's hospital for post-operative management following a primary Fontan procedure between 2005 and 2011 were included. Patients for revision of Fontan or patients admitted to adult Cardiovascular Intensive Care Unit were excluded...

BACKGROUND: Patients with a failing Fontan continue to have decreased survival after heart transplant (HT), particularly those with preserved ventricular function (PVF) compared with impaired ventricular function (IVF). In this study we evaluated the effect of institutional changes on post-HT outcomes. METHODS: Data were retrospectively collected for all Fontan patients who underwent HT. Mode of failure was defined by the last echocardiogram before HT, with mild or no dysfunction considered PVF and moderate or severe considered IVF...

Transcatheter aortic valve implantation (T-AVI) has been established as an alternative to conventional aortic valve replacement. The number of procedures is steadily rising and has reached comparable implant rates to conventional aortic valve replacement. The success of T-AVI is easily explained by their true minimally invasive nature, ease of use, and excellent hemodynamics. Whilst their use was initially limited to high-risk patients, current trends show that more and more intermediate-risk patients are now treated with theses prostheses...
