Is there a relationship between aortic stenosis and dilated cardiomyopathy?

Likely: As aortic stenosis progresses, the heart is straining. One would like to replace the diseased valve before the heart fails by dilation. There are some other risks as well for coronary disease in the natural history.

Later stages: Aortic stenosis may be linked to the dilated cardiomyopathy. Many people with asymptomatic aortic stenosis are followed too long before being offered surgery. The heart then progresses to a dilated stage. Aortic surgery has progressed to per cutaneous option. And will likely increase as technology grows.

Aortic stenosis: The end stage of aortic stenosis is a dilated cardiomyopathy if the patient lives that long. Serious aortic stenosis and dilated cardiomyopathy are relatively incompatible.
