Repair of tetralogy of Fallot with atrioventricular septal defect may be associated with hemodynamic challenges in the postoperative period particularly as left atrial hypertension secondary to left atrioventricular valve dysfunction may exacerbate pulmonary regurgitation and augment low cardiac output. We present a case describing hybrid strategies to treat severe left atrioventricular and pulmonary valve regurgitation with modified balloon expandable stent valves to counter low cardiac output secondary to valve dysfunction...

The optimal timing for pulmonary valve replacement after Tetralogy of Fallot (TOF) repair remains controversial. In this study, we estimated the feasibility of using flow energy loss (FEL) to predict right ventricular (RV) deterioration due to pulmonary regurgitation after TOF repair. We examined RV outflow tract (RVOT) flow in nine patients who underwent TOF or double-outlet right ventricle repair in the intervention group (Group I) and compared them with three healthy children in the control group (Group C)...

Introduction The right ventricular adaptations early after surgery in infants with tetralogy of Fallot are important to understand the changes that occur later on in life; this physiology has not been fully delineated. We sought to assess early postoperative right ventricular remodelling in patients with tetralogy of Fallot by cardiac MRI. Materials and method Subjects with tetralogy of Fallot under 1 year of age were recruited following complete surgical repair for tetralogy of Fallot. Protocol-based cardiac MRI to assess anatomy, function, and flows was performed before hospital discharge using the feed and sleep technique, an unsedated imaging technique...

The present study aimed to investigate the capabilities of the cardiovascular virtual endoscopy (VE) system in diagnosing tetralogy of Fallot (TOF) and performing measurements. A total of 37 patients underwent two-dimensional echocardiography (2-DE) and multi-detector computed tomography (MDCT) examinations. The obtained MDCT images were applied to a cardiovascular VE system. Diagnostic time by VE was first studied and compared with MDCT. Subsequently, with surgical findings as the ground truth, the capabilities of VE, 2-DE and MDCT in diagnosing TOF and its complications were investigated...

Epicardial fat produces multiple proinflammatory cytokines and is associated with adverse cardiovascular events. Inflammation and resultant endothelial dysfunction may play a role in progressive myocardial dysfunction among adults with single ventricle physiology after Fontan palliation, but the potential impact of increased epicardial fat volume (EFV) has not been studied. This study sought to determine if there is greater EFV in Fontan patients compared with a group of repaired tetralogy of Fallot (rTOF) patients...

Right ventricular outflow tract (RVOT) dysfunction is a common hemodynamic challenge for adults with congenital heart disease (ACHD), including patients with repaired tetralogy of Fallot (TOF), truncus arteriosus (TA), and those who have undergone the Ross procedure for congenital aortic stenosis and the Rastelli repair for transposition of great vessels. Pulmonary valve replacement (PVR) has become one of the most common procedures performed for ACHD patients. Areas covered: Given the advances in transcatheter technology, we conducted a detailed review of the available studies addressing the indications for PVR, historical background, evolving technology, procedural aspects, and the future direction, with an emphasis on ACHD patients...

Tetralogy of Fallot (TOF) is one of the most severe forms of cyanotic congenital heart disease (CHD) and is also the most common. Previous genome-wide association study (GWAS) and replication studies have suggested that a polymorphism in the neuropilin 1 (NRP1) gene is significantly associated with the risk of TOF. To further confirm the association between the NRP1 polymorphism and the risk of TOF and to identify additional positive functional single-nucleotide polymorphisms (SNPs) for TOF risk, we systematically screened for functional polymorphisms throughout the regulatory and coding regions of the NRP1 gene...

Aortic arch anomalies refer to congenital malformations of position or branching pattern of the aortic arch. To-date, only a few small studies have documented prenatal detection of aortic arch anomalies. In this article, we share our experience in detecting aortic arch anomalies. Foetal echocardiograms, clinic and genetic histories of 33 patients who had been diagnosed with aortic arch anomaly from 2007 to 2015 were reviewed. In 15 patients, right aortic arch with mirror image branching; in 13 patients, right aortic arch with left ductus arteriosus and aberrant left subclavian artery; in three patients, left aortic arch with aberrant right subclavian artery; in one patient bilateral ductus and right aortic arch with aberrant left subclavian artery and in one patient double aortic arch were detected...

Michael Ma, Richard D Mainwaring, Frank L Hanley
The heterogenous anatomy of Tetralogy of Fallot with major aortopulmonary collateral arteries has engendered a similar degree of diversity in its management and, ultimately, outcome. We summarize our comprehensive treatment paradigm for this lesion evolved over 15 years of experience through 458 patients and the results obtained. An updated analysis of 307 patients treated primarily at our institution is included. A review of recent literature, comparison of management strategies, and discussion of ongoing controversies are provided...

Patients with tetralogy of Fallot, pulmonary atresia, and multiple aortopulmonary collateral arteries (Tet PA MAPCAs) have a wide spectrum of anatomy and disease severity. Management of these patients can be challenging and often require multiple high-risk surgical and interventional catheterization procedures. These interventions are made challenging by complex anatomy that require the proceduralist to mentally reconstruct three-dimensional anatomic relationships from two-dimensional images. Three-dimensional (3D) printing is an emerging medical technology that provides added benefits in the management of patients with Tet PA MAPCAs...

BACKGROUND: Stented bioprosthetic valves (BPVs) are commonly used for surgical pulmonary valve (PV) replacement in postoperative congenital heart disease, but develop structural failure in a time-related fashion. The Melody transcatheter PV (TPV) (Medtronic, Minneapolis, Minn) has been used to treat BPV dysfunction, but there have been few studies in this population. METHODS: We performed a retrospective, multicenter study to evaluate Melody valve function in patients who underwent TPV replacement (TPVR) into a dysfunctional pulmonary BPV...

BACKGROUND: Stillbirth, defined as death of a fetus in utero after 20 weeks of gestation, occurs in 1 to 2% of pregnancies in the United States. Many of these stillborn infants have associated malformations, including chromosome abnormalities, neural tube defects, and malformation syndromes. Other causes are abnormalities of the placenta and maternal conditions, such as pre-eclampsia and obesity. A consecutive sample of malformed stillborn infants can establish the relative frequency and severity of the associated malformations...

Tetralogy of Fallot (TOF) is the most common cyanotic congenital heart defect. It involves anatomical abnormalities that change the normal flow of blood through the heart resulting in low oxygenation. Although not all of the underlying causes of TOF are completely understood, the disease has been associated with varying genetic etiologies including chromosomal abnormalities and Mendelian disorders, but can also occur as an isolated defect. In this report, we describe a familial case of TOF associated with a 1...
