Given the high risk of late repair, patient-specific CFD models were created. Preoperative simulation replicated invasive pressure measurements, and a virtual surgery predicted favorable outcomes. The patient underwent successful surgical reimplantation. Postoperatively, CFD findings at 1 week and 4 months closely matched the virtual prediction and were validated by synchronous four-dimensional flow MRI, demonstrating progressive hemodynamic normalization. Our experience suggests that CFD is a valuable adjunct for surgical planning and longitudinal assessment in complex congenital heart disease.<\/jats:p>\n                  <jats:p>Keywords: Congenital, Cardiac, CT-Angiography, Hemodynamics\/Flow Dynamics, MR-Imaging, Pulmonary Arteries, Aorta<\/jats:p>\n                  <jats:p>Supplemental material is available for this article.<\/jats:p>\n                  <jats:p>\u00a9The Author(s) 2026.
