A member asked:

What's a trileaflet aortic valve?abnormal valve?what's the normal size of ascend.aorta&root?ascending aorta measures 39mm.in 2017,it was 35mm.problem?

A doctor has provided 1 answer

Probably no problem: The valves of the heart are like one-way doors or gates. They open and close to direct the flow of blood into and out of the heart . The aortic valve is able to open and close because it has leaflets. In a normal aortic valve there are three leaflets, and because of this it is called trileaflet. During life the size of the aorta increases. The normal expansion rate is about 1–2 mm/year.
