My left atrial dimensions are borderline, but my doctor didn't tell me anything about them. I am really scared, i also have mild tricuspid regurgitation, and trivial mitral and pulmonary regurgitation. Left atrial volume is 57ml, area is 20cm2, and diameter is 3.7cm. I also have PVC beats (ectopic beats), my dr told me it is caused by anxiety and they are benign. Please I need someone's help.
