Can i live a normal life with minor dilated right atrium?

Depends on the cause: The fact that is "minor" is in your favor; however, to answer your question, we need a DIAGNOSIS (not just a finding). Dilation of the right atrium occurs for various reasons - pulmonic valve stenosis, tricuspid/pulmonary regurgitation (TR/PR), atrial septal defect (ASD), pulmonary hypertension (PAH). Some of these conditions are treatable (ASD); others don't need treatment (TR); PAH is progressiv

Yes: The bottom line is most likely yes. It is hard to be very specific with my answer without more information. If the minor dilation is the only finding on your heart scan then this is probably nothing to get overly worried about - you will probably need to have further scans in the future to keep an eye on it. If this is part of a number of other problems/findings then the picture becomes less clear
