What is the aortic root replacement?

Replacing the root of aorta is a type of surgery used to treat swelling in the root of the largest artery known as aorta. The aortic root is located at the upper end of the aorta where it meets the heart. Swelling or aneurysm in the aorta is most often caused by atherosclerosis, a condition where oily bearings accumulate inside the arteries, causing weakening of the walls. Since the convex aneurysm has a risk of rupture, with perhaps fatal consequences, aortic root surgery is performed to remove the damaged part of the aorta. Instead, a spare part made of artificial fabric or natural tissue is then inserted. What is called the techniques of root replacement valve is left on site an important structure known as aortic valve. Other methods of root replacement are replaced by valve and root. When blood is pumped from the left ventricle, the aortic valve opens to allow it to pass. After throwing the blood, the valve closes to prevent blood leakage back into the heart.

patients who have aortic aneurysms, but whose aortic valves still operate, they can be treated with a root replacement valve. In what is called David's procedure, the damaged section of the aorta is removed and synthetic graft is attached to the heart. The original aortic valve is sewn to the position inside the graft. This type of cardiac surgery is what is referred to as an open heart surgery where the chest has opened and the machine acts as hearts and lungs, giving the body with oxygenated blood while the heart is operated. It may require a hospital stay for about a week and can take up the recovery for six weeks.

For patients whose aortic valves are not functional, the aortic root is replaced by the replacement of the valve and the root. Artificial or natural tissue ingredients or a combination of these two may be used. Synthetic graft containing valve is long -term but carries an increased risk causing a blood clot, cIt is necessary to use anticoagulant drugs after the procedure. Alternatively, the aortic root and the valve can be transplanted from the human tissue donor or the animal valve can be mounted inside the artificial aortic root. The use of biological valves means that anticoagulant drugs are not required but are not as resistant as mechanical versions.
