Abstract In the clinical setting, transcatheter aortic valve implantation (TAVI) has been regarded as an efficient alternative to surgery in high-risk subjects with aortic valve disease. On the other hand, baseline vascular conditions including aortic aneurysm appear to be strongly associated with periprocedural vascular complications as well as long-term mortality in TAVI recipients. Within this context, a co-existing aortic aneurysm should be thoroughly evaluated in the pre-TAVI setting through advanced imaging modalities with regard to its procedural and long-term complication risks. This evaluation should particularly be based on structural features (calcification, thrombus, etc.) of the aneurysmal sac (on top of diameter) to implement the most proper risk-stratification and management strategy (whether or not to proceed with TAVI, etc.). Moreover, TAVI in this setting should be performed by an expert team and with the cautious use of resilient TAVI delivery systems. Therefore, a co-existing aortic aneurysm in TAVI candidates may be considered as an important vascular phenomenon potentially suggesting important implications in these patients.
