What is the exchange of the aortic valve transcatheter?

The

heart is a four -chamber organ that draws blood into the lungs and throughout the body, which usually includes four working valves: aortic, mitral, pulmonic and tricuspid valves. Typically, they allow blood to flow from one chamber to another and are usually controlled by pressure and muscle movement. If one of the heart valves becomes a patient or damaged, the consequences may be fatal and general surgery is required. One procedure that can be done is the replacement of the aortic transcatheter valve in which the compound replacement valve is folded, passes the artery to the heart and expands in place.

The tools called stents are often transmitted to the arteries and expand balloons. These were generally used to open clogged arteries or those that narrowed with age or disease. In the transcatheter aortic valve, the heart valve is placed in a metal scaffold, called a stent. Assembly is usually incorporated into catheters that is inserted into the femoral artery in the foot or arteryby cutting the chest.

Metal stent can be opened by a surgeon when the device is placed in an old aort valve. Special X -ray machines are often used for doctors to find out where the device is. When the stent opens, the device is usually anchored in a place without stitches. Generally, there is no need for bypass surgery or any other kind of open heart procedures. Research has shown that recovery from the replacement of transcatheter aortic valve is usually faster than in more invasive procedures.

patients who undergo a aortic transcatheter valve, sometimes experience heart attacks or strokes, while after surgery they need a pacemaker. Many people with serious cardiac conditions will survive longer with the implanted valve. The study since 2011 continues to evaluate the replacement of the complication valve after the procedure and how they can be minimized. People who qualify for progress often have advanced heart diseaseAnd they are not well enough to undergo traditional surgery.

When the aortic valve becomes narrower than it should be, it can prevent a reasonable blood supply. The replacement of the valve is usually the only long -term solution that can improve the chances of survival. Several valve diseases, blood disorders, and other serious life -threatening conditions may disqualify someone from accepting the aortic valve of transcatheter. The patient's health is usually evaluated by surgeons and other specialists before the operation.
