Minimally Invasive Aortic Pseudoaneurysm Repair with Atrial Septal Defect Occluder.

In patients with ascending aortic pseudoaneurysm, invasive treatment is required regardless of size. The choice between surgical and percutaneous intervention depends on surgical risk and anatomy. Surgical repair, though the gold standard, has a high mortality rate and involves redo sternotomy and cardiopulmonary bypass. Percutaneous closure is an alternative for high-risk patients, using devices like septal occluders, vascular plugs, stent grafts, and coil embolization, selected based on the pseudoaneurysm's characteristics. This case demonstrates the technique of atrial septal defect occluders for aortic pseudoaneurysms in high-risk patients, offering a good alternative to open repair.
