Critical aortic stenosis in a patient with a large saccular abdominal aortic aneurysm: simultaneous transcatheter aortic valve implantation and drive-by endovascular aortic aneurysm repair

Abstract

Elderly patients with aortic stenosis are often deemed too high risk, and consequently turned down for conventional surgery. Transcatheter aortic valve implantation (TAVI) is a safe and an increasingly attractive option in this group of patients. Although TAVI has been shown to be successful and safe, the cardiovascular assessment of other co-morbidities in this susceptible group of patients is critical to ensuring good clinical outcomes. The presence of a saccular abdominal aortic aneurysm (AAA) in our patient was an example of an important co-morbidity which could have a significant impact on the outcome of TAVI, if not managed appropriately. The increased systolic pressure post successful TAVI will result in an increased strain within the wall of the saccular AAA with an increased risk of rupture. Therefore, a timely management strategy for the AAA was necessary. We believe that we report the first case of simultaneous TAVI and endovascular aneurysm repair (EVAR). The patient underwent uncomplicated transfemoral TAVI immediately followed by successful drive-by percutaneous EVAR delivered over the same superstiff guidewire via the transfemoral route. Our case highlights the importance of a detailed assessment in all patients before consideration for TAVI, and the multi-disciplinary team and a management strategy for both pathologies tailored to the patient. The case demonstrates the versatility of trans-catheter techniques which has enabled the treatment of aortic stenosis and abdominal AAA in a single procedure.
