Edwards was received information regarding a patient that presented with an aorta dissection three days post mitral valve surgery.The mitral valve surgery was a minimally invasive procedure and an intra-aortic occlusion device was used.There was no report of issues during the mitral valve surgery, and the surgeon confirmed that the intra-aortic occlusion device worked as intended throughout the procedure.The ascending aorta was 4.2 cm.The patient underwent surgery to correct the aortic dissection.The patient was discharged one week later.As per medical opinion, the potential cause could have been the use of the intra-aortic occlusion device, the guidewire or it could developed spontaneously as aortic dissection is a potential complication for all cardiac surgery.
