Ortic valve replacement for elderly senile

My mother at the age of 88 y old has a sever ortic stenosis . She has also asma for about 60 years.
Her Po2 is over 90% but she complains a lot about brething even when she has open airways.
Is minimal procedure an option with such patients?
Thanks

I think so because of her age and medical history

When an aortic valve is blocked (stenosis) a patient may have a variety of symptoms, including shortness of breath, chest pain, and possibly dizziness or fainting spells.

In general, aortic valves are replaced as opposed to repaired. That would involve open heart surgery.  I don't believe that is an option consiering age and health of your mother.

Balloon valvuloplasty may be an option. This procedure uses a soft, thin tube (catheter) tipped with a balloon to open up the aortic valve passageway. A doctor guides the catheter through a blood vessel in your elbow or groin to your heart and into the narrowed aortic valve. Once in position, a balloon at the tip of the catheter is inflated.

The balloon pushes open the aortic valve and stretches the valve opening. The balloon is then deflated, and the catheter with balloon is guided back out of your body. Balloon valvuloplasty may relieve aortic valve stenosis and its symptoms, especially in infants and children. However, in adults, the procedure isn't usually successful, and the valve tends to narrow again even after initial success. For these reasons, doctors rarely use balloon valvuloplasty today to treat aortic valve stenosis in adults, except in patients who are too sick to undergo surgery (may provide a few years of relief without much risk!).
