Background: Our programmatic approach to tetralogy of Fallot with major aortopulmonary collaterals emphasizes single-stage unifocalization with complete intracardiac repair during infancy. Little is known about suitability for complete repair in patients beyond infancy. We sought to analyze outcomes of our approach in older patients with previously untreated tetralogy of Fallot with major aortopulmonary collaterals. Read More

Background/aim: Although pulmonary valve replacement (PVR) improves ventricular function and symptoms, the benefit and optimal
timing of PVR are controversial. This study aimed to evaluate early response to PVR for right ventricle (RV) dilatation and QRS duration.
Materials And Methods: Retrospective analysis was performed for 32 patients with repaired tetralogy of Fallot (TOF) between March 2005 and October 2017. Read More

Quantification of pulmonary regurgitation (PR), pulmonary flow distribution, and ventricular function is important for clinical surveillance in repaired Tetralogy of Fallot (TOF). Cardiovascular magnetic resonance (CMR) is the established reference, but cost, test duration, and patient discomfort are potential limitations to its serial use. We investigated whether an Abbreviated CMR protocol would alter clinical decisions in TOF from those that would have been made using a full protocol. Read More

Intracardiac hemodynamic forces have been proposed to influence remodeling and be a marker of ventricular dysfunction. We aimed to quantify the hemodynamic forces in patients with repaired tetralogy of Fallot (rToF) to further understand the pathophysiological mechanisms as this could be a potential marker for pulmonary valve replacement (PVR) in these patients. Patients with rToF and pulmonary regurgitation (PR) > 20% ( n = 18) and healthy control subjects ( n = 15) underwent MRI, including four-dimensional flow. Read More

As the prevalence of adult congenital heart disease continues to grow secondary to advances in surgical and diagnostic techniques, it is important for a physician to supplement their examinations with non-invasive imaging techniques to assess their patients. Although a number of these patients have regular cardiology followup, some may be new patients that do not even know their cardiac history. Echocardiography has proven to be a useful tool for this purpose and its utility has expanded drastically with the development of better technology and newer techniques. Read More

Four-dimensional phase-contrast (PC) velocity-encoded flow magnetic resonance imaging (4D flow MRI) is a potentially valuable tool for studying cardiovascular hemodynamics for disease monitoring and/or treatment planning. In this study we compared the performance of two 4D flow MRI pulse sequences - echo-planar imaging (EPI) and segmented gradient-echo (turbo-field-echo or TFE on vendor's platform) - on a clinical 3T system in 6 human subjects including 3 patients with Tetralogy of Fallot (TOF). For aortic flow rate, the coefficients of variation (COV) between 2D and 4D EPI were 7. Read More

Pulmonary artery sling is a rare congenital cardiac anomaly, in which the left pulmonary artery originates from the right pulmonary artery and courses leftward between the trachea and the esophagus. Tetralogy of Fallot associated with pulmonary artery sling is even rarer, and only a few cases have been reported in the literature. We present a case of tetralogy of Fallot associated with pulmonary artery sling that was repaired successfully. Read More

We present a pilot case using an innovative fusion of echocardiogram and MRI achieved with a MATLAB-based imaging programme to explore the feasibility of this imaging strategy in the functional and anatomic assessment of a patient with repaired tetralogy of Fallot requiring pulmonary valve intervention. Echocardiogram and MRI neutralises the disadvantages and limitations of each individual imaging modality and yields important anatomic and haemodynamic information crucial to the treatment decision-making process. Future image fusion strategies can apply to three-dimensional images and image-directed therapy for CHD. Read More

Background: Percutaneous transcatheter pulmonary valve replacement (TPVR) has good clinical and hemodynamic outcomes in treating dysfunctional bioprosthetic valves (BPV) in the pulmonary position. Valve-in-valve therapy can further decrease the inner diameter (ID), potentially resulting in patient-prosthesis mismatch in patients with smaller BPVs.

Long-term outcomes for Tetralogy of Fallot (TOF) have improved dramatically in recent years, but survivors are still afflicted by cerebral damage.

: Congenital heart disease (CHD) is the most common birth abnormality in the structure or function of the heart that affects approximately 1% of all newborns. Despite its prevalence and clinical importance, the etiology of CHD remains mainly unknown. Somatic and germline mutations in cardiac specific transcription factor genes have been identified as the factors responsible for various forms of CHD, particularly ventricular septal defects (VSDs), tetralogy of Fallot (TOF), and atrial septal defects (ASDs).
