40-Year Follow-Up After the Fontan Operation: Long-Term Outcomes of 1,052 Patients

Hypoplastic Left Heart Syndrome : Current Considerations and Expectations

It has been 50 years since Francis Fontan pioneered the operation that today bears his name. Initially designed for patients with tricuspid atresia, this procedure is now offered for a vast array of congenital cardiac lesions when a circulation with 2 ventricles cannot be achieved. As a result of technical advances and improvements in patient selection and perioperative management, survival has steadily increased, and it is estimated that patients operated on today may hope for a 30-year survival of >80%. Up to 70 000 patients may be alive worldwide today with Fontan circulation, and this population is expected to double in the next 20 years. In the absence of a subpulmonary ventricle, Fontan circulation is characterized by chronically elevated systemic venous pressures and decreased cardiac output. The addition of this acquired abnormal circulation to innate abnormalities associated with single-ventricle congenital heart disease exposes these patients to a variety of complications. Circulatory failure, ventricular dysfunction, atrioventricular valve regurgitation, arrhythmia, protein-losing enteropathy, and plastic bronchitis are potential complications of the Fontan circulation. Abnormalities in body composition, bone structure, and growth have been detected. Liver fibrosis and renal dysfunction are common and may progress over time. Cognitive, neuropsychological, and behavioral deficits are highly prevalent. As a testimony to the success of the current strategy of care, the proportion of adults with Fontan circulation is increasing. Healthcare providers are ill-prepared to tackle these challenges, as well as specific needs such as contraception and pregnancy in female patients. The role of therapies such as cardiovascular drugs to prevent and treat complications, heart transplantation, and mechanical circulatory support remains undetermined. There is a clear need for consensus on how best to follow up patients with Fontan circulation and to treat their complications. This American Heart Association statement summarizes the current state of knowledge on the Fontan circulation and its consequences. A proposed surveillance testing toolkit provides recommendations for a range of acceptable approaches to follow-up care for the patient with Fontan circulation. Gaps in knowledge and areas for future focus of investigation are highlighted, with the objective of laying the groundwork for creating a normal quality and duration of life for these unique individuals.

Evaluation and Management of the Child and Adult With Fontan Circulation: A Scientific Statement From the American Heart Association.

### Introduction

The past 60 years have brought remarkable advancements in the diagnosis and treatment of congenital heart disease (CHD). Early diagnosis and improvements in cardiac surgery and interventional cardiology have resulted in unprecedented survival of patients with CHD, even those with the most complex lesions. Despite remarkable success in treatments, many interventions are palliative rather than curative, and patients often develop cardiac complications, including heart failure (HF). HF management in the setting of CHD is challenged by the wide range of ages at which HF occurs, the heterogeneity of the underlying anatomy and surgical repairs, the wide spectrum of HF causes, the lack of validated biomarkers for disease progression, the lack of reliable risk predictors or surrogate end points, and the paucity of evidence demonstrating treatment efficacy.

The purposes of this statement are to review the literature pertaining to chronic HF in CHD and to elucidate important gaps in our knowledge, emphasizing the need for specific studies of HF mechanisms and improving outcomes for those with HF. In this document, the definition of CHD severity is the definition common in CHD documents, including the American College of Cardiology (ACC)/American Heart Association (AHA) guidelines1 for the management of adults with CHD (Table 11–3). The definition of HF corresponds to that found in the multiple guidelines on diagnosis and management of HF. Although nuances and specific details may be controversial,4 the broad definition from the Heart Failure Society of America guidelines states the following: “In physiologic terms, HF is a syndrome characterized by either or both pulmonary and systemic venous congestion and/or inadequate peripheral oxygen delivery, at rest or during stress, caused by cardiac dysfunction.”5 The definition of chronic HF in this document concurs with that of the European Society of Cardiology guidelines, which emphasize chronic HF …

Chronic Heart Failure in Congenital Heart Disease A Scientific Statement From the American Heart Association

Background— The Fontan procedure is a successful palliation for children with single-ventricle physiology; however, many will eventually require heart transplantation. The purpose of this study was to determine risk factors for death awaiting transplantation and to examine results after transplantation in Fontan patients. Methods and Results— A retrospective, multi-institutional review was performed of 97 Fontan patients <18 years of age listed at 17 Pediatric Heart Transplant Study centers from 1993 to 2001. Mean age at listing was 9.7 years (0.5 to 17.9 years); 25% were <4 years old; 53% were United Network for Organ Sharing status 1; 18% required ventilator support. Pretransplantation survival was 78% at 6 months and 74% at 12 months and was similar to 243 children with other congenital heart disease (CHD) and 747 children without congenital heart disease (No-CHD), who were also awaiting transplantation. Patients who were younger, status 1, had shorter interval since Fontan, or were on a ventilator wer...
