REVIEW
Paul Clift, David Celermajer
The Fontan operation is performed as a palliative procedure to improve survival in infants born with a functionally univentricular circulation. The success of the operation is demonstrated by a growing adult Fontan population that exists with this unique physiology. Late follow-up has demonstrated expected and unexpected sequelae, and has shown multisystem effects of this circulation. This review discusses the challenges of managing the late complications in terms of understanding this unique physiology and the innovative therapeutic interventions that are being investigated...

STUDY DESIGN: Case series. OBJECTIVE: To describe transcatheter closure of the Fontan fenestration prior to posterior spinal fusion in two children to prevent paradoxical venous air embolism during the operation. SUMMARY OF BACKGROUND DATA: Scoliosis is common among patients with single-ventricle congenital heart disease who have undergone Fontan operation and spinal surgery can offer physiologic benefits. Venous air embolism is a rare, but important reported complication during spinal surgery performed in the prone position...

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...

Universally fatal only 4 decades ago, the progress in the 3-stage palliation of hypoplastic left heart syndrome and related single right ventricular lesions has drastically improved the outlook for these patients. Although the stage II operation (hemi-Fontan or bidirectional Glenn) and stage III Fontan procedure have evolved into relatively low-risk operations, the stage I Norwood procedure remains one of the highest-risk and costliest common operations performed in congenital heart surgery. Yet, despite this fact, experienced centers now report hospital survivals of >90% for the Norwood procedure...

OBJECTIVES: We aimed to investigate whether early postoperative extubation following the Fontan operation is universally feasible and can be used as a management tool in unstable patients. METHODS: All patients undergoing the Fontan operation in our centre between 2004 and 2013 (n=253) were analysed. Until 2008, patients were extubated according to standard criteria and comprised group 1. Group 2 included all patients presenting after 2009, when early extubation was always aimed regardless of the haemodynamic status...

BACKGROUND: Postoperative echocardiography after congenital heart disease surgery is of prognostic importance, but variable image quality is problematic. We implemented a quality improvement bundle comprising of focused imaging protocols, procedural sedation, and sonographer education to improve the rate of optimal imaging (OI). METHODS: Predischarge echocardiograms were evaluated in 116 children (median age, 0.51 years; range, 0.01-5.6 years) from two centers after tetralogy of Fallot repair, arterial switch operation, and bidirectional Glenn and Fontan procedures...

INTRODUCTION: The Fontan procedure (FP) has become the standard operation for patients with single ventricle physiology. However, a long period of elevated systemic venous pressure and low cardiac output after the procedure result in chronic inflammation and liver cirrhosis, which may eventually lead to the occurrence of hepatocellular carcinoma (HCC). CLINICAL FINDINGS: We described the case of a 16-year-old female who developed HCC after the FP. At 21 months, the patient received a lateral tunnel FP, and 14 years later, she began complaining of abdominal distension, telangiectasia, and fatigue...

Women with a single ventricle circulation palliated with the Fontan operation require specialist multidisciplinary management. We report 14 such cases with successful pregnancies and detail the pathophysiology encountered. A combined obstetric and cardiac service between Chelsea and Westminster Hospital and Royal Brompton Hospital provides care for women with heart disease, and maintains a prospective database of referred women. We searched this database for women with a known Fontan circulation and reviewed the case notes and electronic patient records between January 1994 and December 2015...

Assessment of the pulmonary circulation status including pressure, resistance, size, and absence of anatomical distortion, is crucial to the successful Fontan operation. Most patients are found to have acceptable pulmonary arteries after previous palliation, although some degree of distortion is not uncommon. However, in rare instances, some patients have only one functioning lung with another pulmonary artery seriously hypoplastic or atretic. For theses patients, completion of a Fontan operation will be challenging...

The Fontan operation or total cavopulmonal connection (TCPC) is a palliative surgical correction of rare and complex inborn cardiac malformations that are characterized by univentricular circulation. Protein-losing enteropathy (PLE) develops in 4-13% of patients after the Fontan procedure. Fontan-related PLE leads to secondary combined immunodeficiency marked by hypogammaglobulinemia and predominantly CD4+ lymphocytopenia. Here, we present 3 case reports of patients with secondary immunodeficiency after the Fontan operation...

BACKGROUND: For neonates with critical left ventricular outflow tract obstruction (LVOTO), hybrid procedures are an alternative to the Norwood stage 1 procedure. Despite perceived advantages, however, outcomes are not well defined. Therefore, we compared outcomes after stage 1 hybrid and Norwood procedures. METHODS: In a critical LVOTO inception cohort (2005-2014; 20 institutions), a total of 564 neonates underwent stage 1 palliation with the Norwood operation with a modified Blalock-Taussig shunt (NW-BT; n = 232; 41%), Norwood operation with a right ventricle-to-pulmonary artery conduit (NW-RVPA; n = 222; 39%), or a hybrid procedure (n = 110; 20%)...

BACKGROUND: Coagulation abnormality is associated with a high incidence of intracardiac thrombus (ICT) and systemic thromboembolism in Fontan patients. The biomarker for detecting ICT is currently unknown. METHODS: We retrospectively investigated the underlying coagulation abnormality and useful biomarkers to screen for ICT in adult Fontan patients. We measured various biomarkers of blood coagulation, fibrinolysis, and platelet activity in 122 Fontan patients (Fontan group: median age [P25-P75]: 27 [20-34] years) and compared them to those in 50 patients with atrial septal defect (ASD group: 31 [24-40] years)...

Right atrial isomerism and pulmonary atresia combined with major aortopulmonary collateral arteries are very rare. Surgical treatment becomes more challenging when an extracardiac total anomalous pulmonary venous connection (TAPVC) requiring surgical repair neonatally is also present. We describe a successful staged Fontan operation for a neonate with a single ventricle, right atrial isomerism, pulmonary atresia with major aortopulmonary collateral arteries, a small central pulmonary artery and a supracardiac TAPVC...
