The aortic valve separates the left ventricle from the aorta; it is the valve that separates the chamber of the heart pumping blood into our main artery. The ventricle provides most of the force to carry the blood throughout our body; the valve opens and closes in synchrony with the contraction to make the effort efficient. In aortic stenosis, the valve is narrowed, not opening fully and more rarely not closing fully as well. The inability to open fully makes it more difficult for the left ventricle to pump out the blood making the heart work harder.
As a result of this obstruction blood backs up into the lungs where it may cause shortness of breath; or less blood will be pumped out and reduce the amount of blood getting to the brain, causing dizziness; or in some instances the increased work the heart must do in conjunction with blockages in the coronary (heart) arteries may cause chest pain. In the case of the aortic valve remaining open, aortic regurgitation, the inefficiency of the heart to pump blood out results in similar symptoms. In the presence of these symptoms, it is time to replace the valve.........To Read More....
My Take - I keep being amazed at the non-invasive advancements being made in medicine. But I think the real story is he didn't have this done in Britain with their "free health care". He came to the U.S. instead.
Amazing!
