Valvular Interventions (TAVI)
Saraswati Dayal’s Motiramani Heart Clinic is one of the most trusted Valvular Interventions (TAVI) Treatment Clinics in Shankar Nagar, Raipur Chhattisgarh, India.
Transcatheter aortic valve implantation (TAVI)
Transcatheter aortic valve implantation (TAVI) involves inserting a catheter into a blood vessel in your upper leg or chest and passing it towards your aortic valve.
The catheter is then used to guide and fix a replacement valve over the top of the old one.
The main advantages of this technique are that the heart doesn’t need to be stopped, so a heart-lung (bypass) machine doesn’t need to be used, and it avoids making a large cut (incision) in your chest.
This puts less strain on the body and may mean TAVI is more suitable for people who are too frail to have a conventional valve replacement.
Research suggests the procedure may be as effective as surgery for people in whom surgery would be difficult or risky, and it may result in a faster recovery.
But there’s little evidence to suggest it’s appropriate for people who are suitable for surgery and at a low risk of complications.
Possible complications of TAVI are similar to those of a conventional valve replacement, although the risk of having a stroke after TAVI is higher.
How is the TAVI procedure performed?
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), which is possible when the patient has suitable iliofemoral anatomy and does not suffer from other vessel disease.
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.
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.
Compared with open heart surgery, TAVI may offer the following benefits:
- is less invasive
- is a shorter procedure
- reduces patient time in intensive care
- offers shortened recovery time
- Shorter hospital stay
- offers a more rapid improvement in quality of life
