Cardiac magnetic resonance (CMR) is recommended in post-aortic coarctation (Ao-Coa) repair. The combined use of computational fluid dynamics (CFD) simulations and CMR is a powerful instrument to estimate hemodynamic indices.

Abstract
Cardiac magnetic resonance (CMR) is recommended in post-aortic coarctation (Ao-Coa) repair. The combined use of computational fluid dynamics (CFD) simulations and CMR is a powerful instrument to estimate hemodynamic indices. We report a case of a complex Ao-Coa, operated by extra-anatomic conduit, with a pseudoaneurysm of the aortic arch. A 4D-Flow analysis and CFD simulation, performed starting from CMR acquired 6 years before, highlight an increase in flow complexity in the same site.File in questo prodotto:
