Can you explain "Mobile pulmonary Valve with increased flow velocity."?

I can try. The pulmonary valve keeps blood from flowing back into your heart as it is pumped out into the lungs. I'm not sure what "mobile" means in this context, though my sense is that's what it should be - freely opening and closing. The increased flow velocity means the blood is moving faster than expected across the valve. If you are having any heart or lung symptoms, I'd see your doctor. .
