Hello and hope you are doing well.
Atrial enlargement and ventricular hypertrophy are findings and not diagnosis. There should be an underlying cause which has caused the atrial enlargement and ventricular hypertrophy. Atrial enlargement can occur if there is a mitral valve regurgitation. And ventricular hypertrophy can occur if the ventricles have to work harder to pump blood. Like with hypertension or aortic valvular stenosis.
Hope this helped and do keep us posted.
It can be. If you elaborate, I'll try and help you, as I know quite a bit about this xx
