What diseases can be treated with transcatheter aortic valve replacement?

Model:TAVR Simulator

Transcatheter aortic valve replacement is a minimally invasive interventional treatment method that delivers an artificial valve to the aortic valve ring through a catheter to replace the diseased aortic valve. The treatment process of transcatheter aortic valve replacement is relatively simple. First, a catheter is inserted through a vascular puncture under local anesthesia, and then the catheter delivers the artificial valve to the aortic valve ring. After confirming that the valve position is accurate, the doctor will release the valve and fix it on the aortic valve ring.

The aortic valve is a valve located on the aortic valve ring of the heart. Its main function is to prevent blood from flowing from the aorta to the ventricle. When the aortic valve is narrowed or regurgitated, it will affect the normal blood supply of the heart and lead to a series of cardiovascular diseases.

Aortic valve stenosis refers to the inability of the aortic valve located between the left ventricle and the aorta of the heart to open completely, resulting in a narrowing of the blood channel from the heart to the aorta. It is mainly due to the hardening, thickening and calcification of the aortic valve leaflets, which leads to limited valve opening and hinders blood circulation.

Aortic regurgitation refers to the inability of the aortic valve to close properly, causing blood to flow back from the body's aorta to the left ventricle. Aortic regurgitation may be caused by congenital heart defects, age-related heart changes, infection, hypertension, and heart damage. If the patient has severe aortic regurgitation and cannot tolerate surgical treatment, transcatheter aortic valve replacement can be considered.

Transcatheter aortic valve replacement has the following advantages:

1. Efficient treatment: Transcatheter aortic valve replacement is an efficient treatment method that delivers an artificial valve to the aortic valve position through catheter intervention to replace the damaged aortic valve and restore normal valve function.

2. Low-trauma surgery: Transcatheter aortic valve replacement is a minimally invasive surgery that delivers an artificial valve to the patient's aorta under the guidance of a vascular catheter for replacement. Compared with traditional open-chest surgery, it does not require a large incision, reducing surgical trauma and bleeding risks.

3. High surgical success rate: TAVR has multiple advanced design highlights, which can significantly reduce the risk of serious adverse events, improve the success rate of surgery, and provide safer and more effective treatment effects.

4. Quick recovery: Due to the less trauma of surgery, patients who undergo TAVR can recover faster, reduce hospitalization time and recovery period, and can quickly return to normal life.

5. Improved quality of life: TAVR can quickly and effectively repair heart function, improve the quality of life of patients, reduce symptoms such as shortness of breath and chest tightness, and enable them to resume normal daily activities and physical exercise.
