Improved survival following single ventricle palliation has led to a large population of patients with a Fontan circulation, many of whom will eventually develop Fontan failure. Many of these patients will require heart transplantation. However, more than half of these patients have Fontan failure despite preserved ventricular function. Increasing experience with ventricular assist devices (VAD) in children has paved the way for VAD support in those with failing univentricular circulation. Areas covered: The use of VADs to support the failing univentricular circulation is a relatively new concept...

BACKGROUND: Chronic ventricular pacing (VP) is associated with systolic dysfunction in a subset of pediatric patients with heart block and structurally normal hearts. The effect of chronic VP in congenital heart disease is less well understood, specifically in the single-ventricle (SV) population. OBJECTIVE: To determine the longitudinal effect of VP in SV patients. METHODS: SV patients with heart block and dual-chamber pacemakers requiring >50% VP were compared with nonpaced (controls) SV patients matched for age, sex, and SV morphology...

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: Patients with a borderline left ventricular hypoplasia in the hypoplastic left heart syndrome variant or an unbalanced atrioventricular canal who undergo initial single-ventricle palliation may be candidates for biventricular (BiV) conversion following left ventricle (LV) recruitment procedures. We investigated associations among preoperative parameters and postoperative outcomes in patients undergoing BiV conversion. METHODS: We performed a retrospective review of patients who underwent BiV conversion to determine variables associated with clinical outcomes...

OBJECTIVES: Management strategy for unbalanced complete atrioventricular septal defects (CASVSDs) includes single-ventricle (SV) palliation and primary or staged biventricular (BiV) repair. More recently, BiV conversion (BiVC) from SV palliation and staged BiV recruitment (BiVR) have also been advocated. This study assesses mid-term outcomes in patients with unbalanced CASVSDs according to management strategy. METHODS: Consecutive patients with unbalanced CASVSDs who underwent surgery at a tertiary care centre from January 2000 to February 2016 with institutional review board approval...

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...

BACKGROUND: Patients undergoing palliative surgeries for single-ventricle conditions are affected by multiple comorbidities or non-cardiac conditions. The prevalence, costs and the cost implications of these conditions have not been assessed. METHODS: Administrative costing records from four hospitals in Australia and New Zealand were linked with the Fontan registry database to analyze the inpatient resource use for co-morbid or non-cardiac conditions. Inpatient costing records from the birth year through to Fontan completion were available for 156 patients...

OBJECTIVES: Total cavopulmonary connection (TCPC) performed in the second decade of life has rarely been studied. Thus, we investigated (bicentric study) early and late morbidity and mortality following completion of TCPC in these patients. METHODS: From January 1999 to June 2014, 63 patients (14.5 ± 2.9 years) underwent TCPC (extracardiac conduit). Palliation before completion was an isolated bidirectional cavopulmonary shunt (BCPS) in 3 patients or BCPS associated with additional pulmonary blood flow (APBF) that was either antegrade (Group 1) in 38 (63%) or retrograde (Group 2) in 22 (37%)...

Increased survival rates after corrective or palliative surgery for complex congenital heart disease (CHD) in infancy and childhood are now being coupled with increased numbers of patients who survive to adulthood with various residual lesions or sequelae. These patients are likely to deteriorate in cardiac function or end-organ function, eventually requiring lifesaving treatment including heart transplantation. Although early and late outcomes of heart transplantation have been improving for adult survivors of CHD, outcomes and pretransplant management could still be improved...

BACKGROUND: Neonates with severe forms of Ebstein anomaly present a surgical challenge, and the Starnes operation as single ventricle palliation is highly advocated. Cone reconstruction for tricuspid valvuloplasty (TVP) has become a widely accepted technique, although very few cases of TVP have been reported in neonates. This report describes a surgical strategy for neonatal Ebstein anomaly, with an aim toward biventricular repair. METHODS: Since 2007, 7 neonates or young infants with severe Ebstein anomalies have received TVP at the National Taiwan University Hospital, Taipei, Taiwan...

The Fontan procedure is a common palliative intervention for sufferers of single ventricle congenital heart defects that results in an anastomosis of the venous return to the pulmonary arteries called the total cavopulmonary connection (TCPC). Local TCPC and global Fontan circulation hemodynamics are studied with in vitro circulatory models because of hemodynamic ties to Fontan patient long-term complications. The majority of in vitro studies, to date, employ a rigid TCPC model. Recently, a few studies have incorporated flexible TCPC models, but provide no justification for the model material properties...

Dramatic evolution in medical and catheter interventions and complex surgeries to treat children with congenital heart disease (CHD) has led to a growing number of patients with a multitude of long-term complications associated with morbidity and mortality. Heart failure in patients with hypoplastic left heart syndrome predicated by functional single ventricle lesions is associated with an increase in CHD prevalence and remains a significant challenge. Pathophysiological mechanisms contributing to the progression of CHD, including single ventricle lesions and dilated cardiomyopathy, and adult heart disease may inevitably differ...

OBJECTIVES: Patients with hypoplastic left heart syndrome or related malformations are predominantly treated with a 3-stage palliation. Anatomic or physiologic problems can lead to unplanned additional surgical or catheter interventions during single ventricle palliation. Changes in operative technique may have an impact on the reoperation rate. METHODS: Between 1997 and 2014, 317 Norwood procedures were performed at our centre. A retrospective single centre investigation was carried out concerning incidence, timing, indication and type of unplanned interstage cardiac reoperations and catheter interventions during follow-up of Norwood patients...
