TAVI procedure is used to treat most complex Aortic Stenosisconditions. This procedure is either performed on children or people who are not eligible for the other surgical procedures. The various steps involved in theTAVI procedure are as under:
Before the procedure
A doctor evaluates the patient for possible complications that may arise during the TAVI procedure. A doctor might prescribe some medication to reduce the risk prior to the procedure.
During the procedure
- STEP 1: The area of the body where TAVI has to be performed is numbed using a general anaesthetics.
- STEP 2: Balloon valvuloplasty is performed using a catheter (hollow tube) with a balloon attached to one of its tips. This catheter is inserted into an artery either via the groin or by making a keyhole incision on the side of the arm, leg or chest.
- STEP 3:The catheter is then directed towards the patient’s heart and positioned at the opening of the aortic valve.
- STEP 4:In this step, the balloon attached to the catheter is gently inflated with an aim to make room for the placement of new tissue valve.
- STEP 5: The new tissue valve is placed in position and expanded using a balloon.
- STEP 6: The balloon is then deflated removed along with the catheter.
Finally, a new valve has replaced the damaged valve.
After the Procedure
The patient has to spend a day or two in the intensive care unit for monitoring purpose. However, the overall recovery time is around 12 weeks. After surgery, most people remain asymptomatic and start to feel better. However, they have to take blood-thinning medications for a lifetime to prevent blood clots formation.
