Imaging-based evaluation of cardiac structure and function remains paramount in the diagnosis and monitoring of congenital heart disease in childhood. Accurate measurements of intra- and extracardiac hemodynamics are required to inform decision making, allowing planned timing of interventions prior to deterioration of cardiac function. Four-dimensional flow magnetic resonance imaging is a nonionizing noninvasive technology that allows accurate and reproducible delineation of blood flow at any anatomical location within the imaging volume of interest, and also permits derivation of physiological parameters such as kinetic energy and wall shear stress. Four-dimensional flow is the focus of a great deal of attention in adult medicine, however, the translation of this imaging technique into the pediatric population has been limited to date. A more broad-scaled application of 4-dimensional flow in pediatric congenital heart disease stands to increase our fundamental understanding of the cause and significance of abnormal blood flow patterns, may improve risk stratification, and inform the design and use of surgical and percutaneous correction techniques. This paper seeks to outline the application of 4-dimensional flow in the assessment and management of the pediatric population affected by congenital heart disease.

Background: Surgical pulmonary artery banding (PAB) has been limited in practice because of later requirement for surgical removal or adjustment. The aim of this study is to describe our experience creating a dilatable PAB via transcatheter balloon dilation (TCBD) in congenital heart disease (CHD) patients. Methods: Retrospective chart review of adjustable PAB—outline anatomical variants palliated and patient outcomes. Results: Sixteen patients underwent dilatable PAB—median age 52 days (range 4-215) and weight 3.12 kg (1.65-5.8). Seven (44%) of the patients were premature, 11 (69%) had ventricular septal defect(s) with pulmonary over-circulation, four (25%) atrioventricular septal defects, and four (25%) single ventricle physiology. Subsequent to the index procedure: five patients have undergone intracardiac complete repair, six patients remain well palliated with no additional intervention, and four single ventricles await their next palliation. One patient died from necrotizing enterocolitis (unrelated to PAB) and one patient required a pericardiocentesis postoperatively. Five patients underwent TCBD of the PAB without complication—Two had one TCBD, two had two TCBD, and another had three TCBD. The median change in saturation was 14% (complete range 6-22) and PAB diameter 1.7 mm (complete range 1.1-5.2). Median time from PAB to most recent outpatient follow-up was 868 days (interquartile range 190-1,079). Conclusions: Our institution has standardized a PAB technique that allows for transcatheter incremental increases in pulmonary blood flow over time. This methodology has proven safe and effective enough to supplant other institutional techniques of limiting pulmonary blood flow in most patients—allowing for interval growth or even serving as the definitive palliation.
