Delayed aortic dissection and valve thrombosis after transcatheter aortic valve implantation

We report a case of a 78 ‐year‐old female who presented with type A aortic dissection 22 months following transcatheter aortic valve implantation (TAVI). In addition, preoperative echocardiogram showed high gradients across the aortic prosthesis which was found to be thrombosed. At surgery, the intimal tear appeared t o be non‐acute and anatomically related to the rim of the valve cage. The thrombosed valve was not replaced and the patient received anticoagulation therapy following surgery with significant improvement in valve gradients.
