A member asked:

Got an echo says there is small atrial septal thinning with no crossing flow. what does this mean?

Translation= the wall between the upper heart chambers is thinner than expected but there does not appear to be any fluid crossing through a hole in the structure. ( The wall is thin but all there)

The wall separating your right and left atria has an area of thinness, but there is no hole. Right atrium blood is unoxygenated;left atrial blood is oxygenated obtained in the the lungs). If there were a hole (defect),too much unoxygenated blood goes to the lungs. Symptoms: fatigue, exercise fatigue, leg edema, palpitations, murmur, stroke. You don't have a hole; so no such problems.
