13 Jun Aortic Stenosis: what is it?
Aortic stenosis is a calcified valve that partially obstructs blood flow out of the heart into the main artery, the aorta
The biggest problem for the heart is that the main pumping chamber, the left ventricle, needs to pump much harder to disgorge enough blood out into the aorta to supply the whole body with blood. By pumping harder, the left ventricle will need to generate a lot More pressure and in so doing the ventricle will eventually hypertrophy and even result in heart failure. There are many treatments available for aortic stenosis, including some modern less invasive techniques compared to open heart surgery that I will talk about another videos in this series.
