The left atrium is mildly dilated. There is a mild aortic sclerosis.
The aortic valve is trileaflet. There is a prominent "B Hump" in the mitral valve, consistent with elevated left ventricular end-diastolic pressure. There is a trace of mitral regurgitation. The pulmonic valve is not well visualized. The study was technically difficult.

What does that mean?

The left atrium is the chamber that receives oxygenated blood from the lungs.



The left atrium size can be affected by valvular abnormalities and pressures.  The velocity and LV systolic pressure (pumping phase) are measures of the filling pressures of the heart and that should be analyzed to determine if yours were in the normal range.  If the valve (one-way from atrium to ventricle) has a narrow opening, the gradient pressure will be higher than normal causing dilatation.

You didn't list any left ventricle abnormality so apparently and I am assuming that isn't part of the problem.  If the LV is involved filling pressures would be involved measured by regurgitant velocity and RV systolic pressure.
