The report is very brief but it says that there is a problem with two of your heart valves.
The triscupid valve is leaking severely (TR= triscupid regurgitation) and the mitral valve does not open very well (mitral valve area MVA is well below normal).
This causes that your heart does not pump very efficiently and has to work (too) hard to supply your body of oxygen rich blood.
If such a condition remains for a longer period, the heart starts to compensate, leading to dilation of the heart chambers (dilation of LA, RA, RV).
What did your cardiologist say about it?
