Know What Is Aortic Valve ReplacementAortic Valve Replacemen - Aortic valve replacement or aortic valve replacement is an open heart surgery procedure performed to treat patients with aortic valve disorders. This procedure aims to replace the aortic valve that fails or is damaged. The damaged aortic device replaces with an artificial aortic valve, from synthetic material or animal tissue.
The aorta is the largest arterial line vessel that is directly connected to the heart and is responsible for flowing oxygen-rich blood from the heart throughout the body. Before entering the aorta, blood from the left ventricle of the soul passes through the aortic valve, which is one of the four devices that the centre has. The aortic valve that does not function normally will disrupt blood flow, so the heart will work extra to meet the needs of the blood supply throughout the body.
Indications for Aortic Valve ReplacementThe aortic valve replacement procedure is carried out in the following conditions:
- Aortic valve regurgitation, a situation in which the aortic valve of the heart cannot close tightly. This condition causes a portion of the blood supply already in the aorta to return to the left ventricle of the heart. Symptoms of aortic valve regurgitation can include fatigue and shortness of breath (dyspnea) due to disruption of the blood supply throughout the body.
- This condition causes blood flow from the left ventricle to the aorta to be blocked, so that blood builds up not only in the left ventricle but also in the heart that drains blood to the left ventricle, namely the atrium. ), shortness of breath, heart palpitations, and fatigue quickly even if only doing light activities.
No medicine can cure aortic valve disease. Therefore, the aortic valve replacement procedure is the main action to defeat. Warning for Aortic Valve Replacement
Patients with aortic valve disease who also have kidney and lung disease, need to be careful before undergoing aortic valve replacement surgery.
Preparation of Aortic Valve Replacement
Consult your doctor about the procedure to follow, the risks, or complications that can occur. Before surgery, the doctor will do a physical examination, medical history especially whether he has an allergy to anaesthesia (anaesthesia), and do blood tests, electrocardiography (ECG), echocardiography, and X-ray examination.
Tell the doctor about the medicines consume. The doctor will assess whether or not to stop the drug. Patients need to fast eating and drinking since the night before surgery, and not smoking before the surgical procedure performer.
Aortic Valve Replacement Procedure
Aortic Valve Replacemen - Valve replacement surgery lasts for several hours depending on the patient's condition. The doctor will begin the procedure by administering anaesthesia. The anaesthetic will make the patient unconscious and not feel pain during the operation.
After giving anaesthesia, the heart surgeon will make a long incision of about 25 cm in the middle of the sternum, or you can also make a small incision as access to open the heart area. A hose or catheter will connect between the heart, large base vessels, and a machine that replaces the work of the heart. During surgery, the centre will stop pulsing.
After that, the doctor will give medicines that can stop the heart from working. This condition allows the doctor to perform surgery on the heart.
The doctor will remove the damaged aorta when the valve is open. A new aortic valve replaces the old aortic valve by stitching using fine threads. The pipe used can be:
Artificial mechanical valve
Valves made from animal tissue (bioprosthesis), such as cattle or pigs or cloth taken from the human heart (homograft).
About 80 per cent of patients uses aortic bioprosthesis valves. This network is believed to be safer and last up to 15-20 years.
After stitching, the function of the heart will return to normal with the help of an electric shock device. The heart bypass is then released. Next, the breastbone will be connected again with wires. Surgical wounds on the chest will close with some stitches.
The method of calling a valve can also do without an incision. This procedure describes transcatheter aortic valve replacement (TAVR) or also called transcatheter aortic valve implantation (TAVI).
The doctor will open the heart through the blood vessels in the legs or make a small incision in the chest. The hose connect through
