What happens when the lungs receive blood from the left atrium of the heart?

Lungs. Normally the lungs do not receive blood from the left atrium. Blood travels from the right atrium to the right ventricle to the lungs and then comes back from the lungs to the left atrium to the left ventricle and is then pumped out through the aorta to the rest of the body. Read more...

If you have an echo suggesting that the the left atrium appears small. Is it possible that the heart was originally small within normal limits and that the right atrium may of enlarged making the left atrium appear small? Also, if the ECG also shows point

Echo. I note you list scoliosis has condition you have. Echo appearance is highly beam angle influenced. It is possible you have a normal size L atrium but the beam angles because of the scoliosis make it look small. If everything else is OK, no reason for you to be concerned unless the cardiologist is concerned about the echo. Read more...

A recent electrocardiogram revealed an enlarged left atrium. I'm only 25 but heart disease runs in my family. How serious of a condition is this?

Something to watch. Left atrial enlargement may be associated with some risk for future cardiovascular problems including atrial fibrillation (a rhythm problem) and possibly stroke. It also may suggest diastolic dysfunction (strain of the heart at rest). But all of these are conditions associated with aging and the risk of atrial enlargement found in young life may be different. Find a good cardiologist to work with! Read more...
Depends. There are 2 question: is the atrium truly enlarged and, if so, is there a reason for it: both can be answered with an echocardiogram. Usual reasons for left atrial enlargement are: hypertension, left ventricular diastolic dysfunction, atrial fibrillation, mitral valve disease, and atrial septal defect. The EKG is very indirect. The echo is much more accurate as it directly measures LA size. Read more...
