Aortic Terms Definitions
Aortic Terms Definitions
Betty,
I should change my avatar to a fish biting the bait for responding to this one.
Here follows my version of these definitions from my personal lexicon...
Aortic Stenosis is a narrowing of the aortic valve which restricts the flow of blood through it into the aorta. It can be caused by various things, most frequently by calcification, scar tissue, or a congenitally narrow valve.
Aortic Regurgitation is when blood pumped past the valve leaks back through the leaky valve into the chamber it was pumped out of. It is usually caused by the valve being partially blocked open by hard calcium deposits, or may occur when the valve's shape has been deformed by either an expanded aortic root or asymmetrical heart growth (hypertrophy) to the extent that the leaflets don't mesh closed completely.
Aortic Insufficiency is when the aorta is not completely engorged with blood from the output of the heart's beat. The most frequent causes are Aortic Stenosis or Aortic Regurgitation (usually a combination of the two), heart failure (ineffective ventricle, low ejection fraction), or Mitral Regurgitation (when the ventricular squeeze winds up pushing blood both ways, through the aortic valve into the aorta, but also back through the leaky mitral valve into the atrium).
It may be that some technicians use the term insufficiency in such a way that it can be meant to imply regurgitation, with respect to other diagnostic results that are detailed outright. But as I understand it, regurgitation is not actually required for aortic insufficiency. Examples would include congenital aortic stenosis, and heart failure occurring in a heart with two, functional mechanical valves, aortic and mitral.
