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.1. What is percutaneous aortic valve replacement?
Percutaneous aortic valve replacement TAVI is a technique that was first performed in 2002, on patients with tight aortic stenosis who were denied surgery because scientists thought the risk of surgery was too high. Presented by interventional cardiologist Dr. Alain Cribier. This technique has been officially and routinely applied for about 10 years now. Vinmec is the first hospital in Vietnam to perform this technique independently.2. Pros and cons of percutaneous aortic valve replacement
The advantages of percutaneous aortic valve replacement are known:Less invasive, gentler and simpler than conventional aortic valve replacement surgery. Doctors do not need to cut along the patient's sternum, do not have to run an artificial cardiopulmonary bypass machine, do not have general anesthesia, so the risk of complications is minimized. Reduce postoperative time as well as shorten hospital stay. High success rate. This is a lifesaver for patients who cannot tolerate surgery because of old age, weakness or chronic medical conditions. However, the percutaneous aortic valve replacement technique also has certain disadvantages:
The cost is still high. Requires appropriate aortic valve structure and access lines.
3. Indications - Contraindications of TAVI . technique

Patients aged 60 years or younger, with severe aortic stenosis, valve orifice area less than 1cm2, The mean differential pressure across the valve is more than 40 mmHg. Patients are symptomatic and the prognosis is less than 1 year. The patient had aortic and peripheral artery anatomy suitable for the technique. The patient wishes to perform TAVI technique for treatment. Patients are appointed by the “cardiology team” including an internal cardiologist, a cardiologist, an interventional cardiologist, and an anesthesiologist. 3.2. Contraindications Patients are not indicated for percutaneous aortic valve replacement in the following cases:
New myocardial infarction (within 30 days) New cerebrovascular accident (within 6 months) aortic valve smaller than 17 mm or larger than 25 mm. These “thresholds” gradually changed as new devices used in the procedure were introduced. Hypertrophic cardiomyopathy, with or without obstruction Left ventricular systolic function LVEF less than 20% Patient is allergic or intolerant to antiplatelet agents Echocardiogram shows tumor, thrombosis, or a lump in the heart Has many serious medical conditions, life expectancy is less than 12 months
4. Vinmec's advantages in implementing TAVI
Vinmec là bệnh viện đầu tiên tại Việt Nam thực hiện kỹ thuật này độc lập
Vinmec is the only place in Vietnam that is equipped with a Hybrid room that can perform the procedure. Presenting difficult and complex techniques, modern equipment brings the best image quality to the surgeon. Is the only place in Vietnam awarded the certificate of "independent aortic valve replacement" in Vietnam. The direct implementation team is a "cardiovascular team" that works in unison and support, with the cardiovascular surgeon always accompanying the procedure. 4.2. The most modern and synchronous equipment The Hybrid operating room is invested with modern equipment such as: DSA angiography machine, anesthesia machine with integrated hemodynamic monitoring software most closely. (PiCCO system, entropy,...). With these equipment, the Hybrid operating room can meet the requirements of surgery and percutaneous aortic replacement intervention to treat congenital heart disease, stenosis or aortic regurgitation with modern minimally invasive techniques. most invasive, safe, help patients recover health soon.
