Navigating Complex Cardiac Defects: A Neonatal Case of Pentalogy of Fallot With Vascular Anomalies Identified via Cardiac CT Angiography.

The pentalogy of Fallot stands out as one of the rarest and most complex congenital heart defects. Pulmonary artery stenosis, a ventricular septal defect, an overriding aorta, right ventricular hypertrophy, and atrial septal communication characterize it. Due to its complexity and associated malformations, advanced imaging methods, such as cardiac CT angiography, have become essential for proper characterization. In this study, we report the case of a 35-week gestation newborn diagnosed with pentalogy of Fallot and additional vascular malformations, identified through cardiac CT angiography.
