How is the TAVI procedure performed?
Year-on-year, the use of TAVI in patients with severe aortic stenosis is increasing. In Europe, this growth resulted in 39,931 TAVI procedures performed in 2016, compared with 10,660 in 20121 and following expansion of the patient cohort indicated for treatment with transfemoral TAVI,2 this is likely to increase further in the coming decade, potentially becoming the standard of care for many patients with severe aortic stenosis.3
The TAVI procedure can be performed through several access routes, most commonly via the transfemoral approach (utilised in more than 90% of patients at most centres),4 which is possible when the patient has suitable iliofemoral anatomy and does not suffer from other vessel disease.5
Iterative improvements in TAVI valve and delivery systems have contributed to the increased suitability of patients for transfemoral TAVI and the increased numbers of TAVI procedures.3
Transcatheter aortic valve implantation
TAVI may be advantageous compared with surgery
The recently released results of the PARTNER 3 Trial proves SAPIEN 3 TAVI is superior to surgery on the primary endpoint (all-cause death, all stroke, and rehospitalization) and multiple pre-specified secondary endpoints.6 Learn more about PARTNER 3 Trial.
Compared with open heart surgery, TAVI may offer the following benefits:
- is less invasive10
- is a shorter procedure11
- reduces patient time in intensive care7
- offers shortened recovery time12
- Shorter hospital stay13
- offers a more rapid improvement in quality of life14
TAVI has a low risk of major adverse cerebrovascular and cardiac events.15 Furthermore, stable valve durability has been demonstrated up to 5 years of follow-up.7, 16
SAPIEN 3 TAVI is now approved for use in low-risk patients with severe aortic stenosis.
