Transcatheter Aortic Valve Replacement - Know More About It!

Transcatheter aortic valve replacement (TAVR), also known as TAVI, is a minimally invasive surgical procedure. Doctors use this procedure to repair a valve instead of removing the old damaged one. In this procedure, a replacement valve is placed in the position of the aortic valve.

How does placing a new valve inside the old valve work?

Similar to placing a stent inside an artery, the TAVR procedure allows for a fully collapsible valve to be placed inside the damaged valve with the help of a catheter. 

Once the new valve starts to function, it pushes the old valve away and takes over the job of controlling blood flow.

How is the procedure carried out?

In the regular valve replacement method, an open heart procedure is necessary. It requires the chest to be surgically opened up to complete the procedure.

On the other hand, the TAVR procedure is carried out through small incisions that do not involve moving the chest bones. 

There are two ways in which the TAVR procedure is carried out –

1. The doctor places the new valve through the femoral artery. This method does not require any incisions to made on the chest.

2. In the second method, a small incision is made on the chest through which the new valve is placed. 

The benefit of this method is that the recovery time is shorter compared to traditional valve surgery. The duration of the hospital stay is also shorter (3-5 days).

Once the procedure is over, you have to stay overnight at the ICU. This is done so that your vitals can be monitored on a regular basis. You will also have to take blood thinners to prevent blood clots. The doctor will advise you on the duration of the blood-thinning medications. 

Outlook

TAVR can greatly help those who are suffering from aortic stenosis and can’t undergo surgery. Post-surgery, you will have to go for follow-up check-ups so that the doctor can monitor your health. If you notice any warning signs, let the doctor know immediately.
