Aortic (aortic) stenosis accounts for 2% of cardiovascular disease and is the most common cause of left ventricular ejection fraction obstruction. The most common acquired causes of aortic stenosis are rheumatic heart disease and fibro-calcium degeneration of the aortic valve in the elderly. This is the most common valvular disease, accounting for a quarter of all heart valve disease cases with 80% of patients with aortic stenosis being male (male:female ratio is 2:1).

Asymptomatic aortic stenosis is a dangerous disease, with no obvious symptoms that can only be discovered by chance in clinical and echocardiography during physical examination. The disease can only be effectively treated when replacing the aortic valve, drug treatment only works to reduce symptoms, making the patient more comfortable.

Percutaneous aortic valve replacement (TAVI) is the optimal solution for patients with aortic stenosis. Vinmec Times City International General Hospital has used the method and successfully treated many patients.

In patients with stenosis or regurgitation, the heart has to work harder, leading to heart failure, causing significant impacts on health and quality of life. Heart valve replacement is considered an effective treatment solution in these patients.

In the elderly, the systems in the body are weakened, so when treating heart disease, it is necessary to be extremely cautious. Percutaneous aortic valve replacement (TAVI) is an advanced technique in the world and has a high success rate.

Anesthesia for patients undergoing percutaneous aortic valve replacement is a complex anesthetic method but has opened up hope for patients with high-risk aortic valve stenosis who cannot undergo conventional surgery.

Heart valve replacement surgery is a necessary treatment when patients have heart valve damage that cannot be repaired or does not respond to medical treatments. This treatment has saved countless lives.
