WELCOME to the ATRIAL SEPTAL DEFECT COMMUNITY: This Patient-To-Patient Community is for discussions relating to Atrial Septal Defect (ASD) which is a hole in the part of the septum that separates the atria (the upper chambers of the heart). This hole allows oxygen-rich blood from the left atrium to flow into the right atrium instead of flowing into the left ventricle as it should. This means that oxygen-rich blood gets pumped back to the lungs, where it has just been, instead of going to the body.
Older people are more likely to develop heart valve disease. It's estimated that 1 in 8 people age 75 or older have at least moderate heart valve disease.
About 1 to 2 percent of people are born with an aortic valve that has two flaps instead of three. Sometimes an aortic valve may have three flaps, but two flaps are fused together and act as one flap. This is called a bicuspid or bicommissural aortic valve. People who have this congenital condition are more likely to develop aortic heart valve disease.
The major risk factors for acquired heart valve disease are:
