BACKGROUND: Identification of prenatal ventriculoarterial connections in fetuses with conotruncal anomalies (CTA) remains one of the greatest challenges for sonographers performing screening examinations. Herein, we propose a novel protocol of 4D volume analysis that identifies ventriculoarterial connections and evaluate its clinical utility in routine screenings. METHODS: Twenty-nine cases of transposition of the great arteries (TGA), 22 cases of double-outlet right ventricle (DORV), 36 cases of tetralogy of Fallot (TOF), 14 cases of truncus arteriosus (TCA), and randomly selected 70 normal fetuses were reviewed in this study...

BACKGROUND: Reconstruction of the right ventricular outflow tract with a conduit is an established surgical procedure in congenital heart disease and reinterventions are common. OBJECTIVE: An increasing number of patients have a conduit, but there are few population-based studies of long-term outcomes after conduit surgery, reoperations, and transcatheter pulmonary valve replacement. METHODS: In April 2015, all adult patients with a conduit were identified in the Swedish National Registry for Congenital Heart Disease (SWEDCON)...

OBJECTIVE: This paper presents a framework for temporal shape analysis to capture the shape and changes of anatomical structures from 3D+t(ime) medical scans. METHOD: We first encode the shape of a structure at each time point with the spectral signature, i.e., the eigenvalues and eigenfunctions of the Laplace operator. We then expand it to capture morphing shapes by tracking the eigenmodes across time according to the similarity of their eigenfunctions. The similarity metric is motivated by the fact that small shape deformations lead to minor changes in the eigenfunctions...

PURPOSE OF REVIEW: Imaging is essential for the management of adults with repaired tetralogy of Fallot (rToF). Echocardiography and cardiac magnetic resonance imaging are the central modalities to assess rToF. Here we review recent literature on imaging rToF, focusing on echocardiography and advances in assessment of cardiac mechanics. RECENT FINDINGS: Several two-dimensional, three-dimensional, and Doppler echo parameters have been proposed to assess pulmonary regurgitation, right ventricular volumes and ejection fraction, but most of them still have important limitations in their feasibility and reliability compared to cardiac magnetic resonance (CMR)...

Assessment of left ventricular (LV) dysfunction is vital in patients with repaired tetralogy of Fallot (rTOF). The early diastolic intraventricular pressure gradient (IVPG) in the LV plays an important role in diastolic function. IVPG is calculated as the intraventricular pressure difference divided by the LV length, which allows to account for differences in LV size and therefore calculate IVPG in children. We aimed to investigate the mechanisms of LV diastolic dysfunction by measuring mid-to-apical IVPG as an indicator of the active suction force sucking blood from the left atrium into the LV...

OBJECTIVES: To determine the early, intermediate and long-term outcomes of pulmonary atresia with ventricular septal defect (PA/VSD) Types I, II and III initially palliated by a right ventricle to pulmonary artery (RVPA) connection. METHODS: We performed a retrospective study from 2000 to 2014 that included 109 patients with PA/VSD who had undergone an RVPA connection (tetralogy of Fallot and PA/VSD Type IV excluded). The end-points of this strategy were adequate pulmonary artery tree post-palliation, second palliation, biventricular repair, right ventricular pressure post-biventricular repair and late reoperation...

Ebstein's anomaly in combination with tetralogy of Fallot (TOF) is rare. We report a male infant with these combined anomalies who presented with severe cyanosis, heart failure, and respiratory distress after birth. Biventricular repair was successfully performed with 1-stage correction of his ventricular septal defect (VSD), right ventricular outflow tract (RVOT) obstruction, and tricuspid regurgitation. The downward displaced tricuspid valve was also restored to the normal annulus position. The infant recovered well...

Tetralogy of Fallot with absent pulmonary valve syndrome (TOF/APV) is a rare congenital malformation. Although pulmonary artery (PA) anomalies have been observed in TOF, its association with disconnected PA is extremely rare. We report successful stenting of the disconnected left PA in a 3-year-old boy with TOF/APV followed by surgical reimplantation. The significance of this transcatheter intervention for guidance during surgery and the importance of visualizing a ductal stump on angiography as an indicator of disconnected PA are discussed...

There has been tremendous growth in the population of adults with congenital heart disease (CHD) over the last few decades because of advances in medical care. Whereas some cases are cured during childhood, most patients instead undergo palliation, which leaves them at risk for late complications. Lifelong clinical follow-up involving serial multimodality imaging is helpful to monitor and guide the treatment of late complications. Imaging of these individuals is challenging because of their unique anatomy and therefore requires careful consideration on a case-by-case basis...

Recent data showed a right ventricular dyssynchrony in patients with tetralogy of Fallot (TOF). Percutaneous pulmonary valve implantation (PPVI) has become an important procedure to treat a pulmonary stenosis and/or regurgitation of the right ventricular outflow tract in these patients. Despite providing good results, there is still a considerable number of nonresponders to PPVI. The authors speculated that electrical dysfunction of the right ventricle plays an underestimated role in the outcome of patients after PPVI...

OBJECTIVES: Although evidence exists of broadly defined memory impairment among adolescents with critical congenital heart disease (CHD), nuanced investigations of declarative memory in this at-risk population have not been conducted. This study had two primary aims: (1) to conduct a fine-grained analysis of a range of relevant learning and memory processes in adolescents with critical biventricular CHD, and (2) to identify risk, odds, and predictors of memory impairment. METHODS: Data were combined from two single-center studies of neurodevelopmental outcomes in critical CHD...

BACKGROUND: The number of patients with congenital heart disease (CHD) is increasing worldwide and most of them will require cardiac surgery, once or more, during their lifetime. The total volume of cardiac surgery in CHD patients at a national level and the associated mortality and predictors of death associated with surgery are not known. We aimed to investigate the surgical volume and associated mortality in CHD patients in England. METHODS: Using a national hospital episode statistics database, we identified all CHD patients undergoing cardiac surgery in England between 1997 and 2015...

BACKGROUND: A substantial proportion of infants born with tetralogy of Fallot (TOF) die in infancy. A better understanding of the heterogeneity associated with TOF, including extracardiac malformations and chromosomal anomalies is vital to stratifying risk and optimizing outcomes during infancy. METHODS: Using the North Carolina Birth Defects Monitoring Program, infants diagnosed with TOF and born between 2003 and 2012 were included. Kaplan-Meier survival curves were used to estimate cumulative 1-year mortality, stratified by the presence of concomitant birth defects (BDs) and chromosomal anomalies...

Tetralogy of Fallot is the most common form of cyanotic congenital heart disease. As a result of the surgical strategies employed at the time of initial repair, chronic pulmonary regurgitation (PR) is prevalent in this population. Despite sustained research efforts, patient selection and timing of pulmonary valve replacement (PVR) to address PR in young asymptomatic patients with repaired tetralogy of Fallot (rToF) remain a fundamental but as yet unanswered question in the field of congenital heart disease...

AIM: To investigate cardiac magnetic resonance (CMR)-derived parameters to determine a convenient index reflecting the degree of pulmonary regurgitation (PR) after Tetralogy of Fallot (TOF) repair. MATERIALS AND METHODS: Sixty-three patients (age at CMR study, 23.6 [10.2-34.7] years, 55.6% male) underwent CMR after TOF repair. PR was quantified using ventricular stroke volume difference and phase-contrast mapping of the main pulmonary artery flow. In both approaches, the PRV index (PRVI) and the PR fraction (PRF) were calculated and correlated to the right ventricle end-diastolic volume index (RVEDVI) and the right ventricle end-systolic volume index (RVESVI)...

Cases of uncorrected adult tetralogy of Fallot are rare and mostly manifest secondary to complications. A 30-year-old man presented with progressive breathlessness and severe chest discomfort. Echocardiography revealed tetralogy of Fallot with a left ventricular apical clot and DeBakey type I dissection of the aorta. The patient underwent successful surgical correction. The combination of preoperative complications in the setting of uncorrected tetralogy of Fallot, such as a left ventricular clot and DeBakey type I dissection of the aorta, is very rare...

The association between Down syndrome and pulmonary hypertension could contribute to more severe pulmonary regurgitation after tetralogy of Fallot repair and possibly earlier pulmonary valve replacement. We compared cardiac magnetic resonance measures of pulmonary regurgitation and right ventricular dilation as well as timing of pulmonary valve replacement between those with and without Down syndrome after tetralogy of Fallot repair. Review of our surgical database from 2000 to 2015 identified patients with tetralogy of Fallot with pulmonary stenosis...

INTRODUCTION: Pulmonary artery aneurysms are a rare entity. Etiologies of these findings are multiple, but they are exceptionally associated with Fallot's Tetralogy. In this study, we present an unusual case of an important aneurysm of the left pulmonary artery associated with Fallot's Tetralogy disease. CASE PRESENTATION: A 30-year-old woman has been admitted for dyspnea and cyanosis. The data which had been obtained from echocardiography, cardiac catheterization, and angio-magnetic resonance imaging (MRI) suggested the existence of an important aneurysm of the left pulmonary artery associated with a regular Fallot's disease with a pulmonic stenosis...
