Transapical Closure of Re-entry Tear in Aortic Dissection With the Off-Label Use of a Gore Cardioform Septal Occluder Using 3D-Printed Simulation

We report a novel transapical approach to treat a challenging residual aortic dissection following prior type A dissection repair.Because of the complex anatomy and high surgical risk, a multidisciplinary team opted for a transapical transcatheter closure of the re-entry tear using a Gore Cardioform Septal Occluder.A custom 3D-printed model of the patient's aorta was used to simulate the device deployment.The procedure resulted in the successful exclusion of the false lumen and stabilization of the aneurysm, demonstrating the potential of this alternative technique in managing complex aortic dissections when conventional treatments are judged at too high risk.
