Thank you for your query
I admire your positive outlook.
Aortic stenosis (narrowed aortic valve) can range from mild to severe.
Moderate to severe stenosis are usually symptomatic. When the symptoms are too severe and threaten life, it needs to be replaced.
The most common and relatively safe procedure is open heart valve replacement. This will take a longer recovery time but has less risk of
stroke and fewer vascular complications as opposed to TAVR (transcatheter
aortic valve replacement)
TAVR is usually reserved for those who cannot undergo the strain of open heart surgery.
From your query, I understand that there is still time( about 5 years) before you absolutely have to have surgery. There are certain precautions and medications that can be taken to slow the progression of the stenosis.
These reduce the burden on the heart and reduce the effect of imflammatory/metabolic/dynamic processes that worse the stenosis.
Healthy diet, moderate exercise (as advised by your cardiologist) will also help to slow the disease process.
Hope this information is helpful. If you have further queries, we'd be happy to answer.
Wish you the best of health
