Aortic stenosis is a common heart disease in which the left ventricle cannot expel blood normally, causing shortness of breath, chest pain, tiredness, or loss of consciousness. If the stenosis is very advanced, a transcatheter aortic valve implant (TAVI) is necessary.

The procedure, which lasts approximately one to two hours, consists of making a small incision in the femoral artery at the groin and insert a new aortic prosthesis through a catheter. As it is not a surgical intervention, the risks are lower and the recovery takes about a week.

TAVI is the best option for high-risk patients for conventional surgery, the elderly, or those with liver, kidney, and lung problems.

If you have severe aortic stenosis, your ABC doctor will perform various tests to assess your condition and make the most appropriate decision for your health and well-being.

Possible risks and complications:

Although the transcatheter aortic valve implant (TAVI) is regularly a safe intervention, as in any procedure, there may be some risks and complications such as:

Heart attack.
Arrhythmias and the need for a pacemaker.
Blood vessel complications.
Valve slipping out of place or leaking.
Kidney disease.
Infection.
