Aortic Valve In Valve Implantation
The aortic valve is one of the four valves that regulate blood flow through the heart. It is present between the left ventricle and the aorta. The main function of aortic valve is to allow blood to leave the heart, from the left ventricle to the aorta and on to the body.
Aortic valve implantation is the procedure to treat diseases affecting the aortic valve. When the aortic valve isn’t working properly, it can interfere with the blood flow and also forces the heart to work harder to supply the necessary blood to the rest of the body.
Why it’s done
There are different reasons which affect the working of our aortic valve. Some of them are –
- Aortic valve regurgitation – it is the condition in which blood flows backward through the aortic valve into the left ventricle each time the ventricle relaxes. In normal condition, blood flows one way from the ventricle to the aorta. This causes the valve to leak.
- Aortic valve stenosis – in this condition, the valve becomes narrowed or obstructed. It makes harder for the heart to pump blood into the aorta. It occurs due to thickening of the valve’s closure flaps or post-inflammatory changes such as those associated with rheumatic heart disease.
- Congenital heart disease – these are the diseases which are present since birth. They may lead to either aortic valve regurgitation or stenosis. These diseases stop the aortic valve in functioning in proper manner.
- Before the procedure, your food intake and medications will be discussed. You will be communicated when to stop eating and drinking the night before the surgery.
- You will be administered anesthesia so that you won’t feel any pain or uneasiness.
- A blood pressure machine will be connected to you that keep the blood moving through your body during the procedure.
- During the procedure, the heart is accessed through a blood vessel in the leg or via a small incision in the heart.
- A hollow tube known as catheter is guided through veins to the aortic valve. Once it is positioned in correct manner, a self expandable replacement valve is implanted.
- You will spend a day or more in the Intensive Care Unit (ICU) depending on the outcome.
