Hello doctor,

My child had critical pulmonary stenosis and had balloon dilation at three months. She is now 13. She has moderate pulmonary regurgitation, her LV ejaculation fraction is 69 %. She has a mildly dilated RV and pulmonary artery. She gets breathlessness. Should I be concerned?

Hi,

Welcome to icliniq.com.

As per cardiac MRI (attachment removed to protect patient identity), the degree of pulmonary valve regurgitation is moderate at the most with only mildly dilate RV. Please be assured at this stage. However, she still needs yearly follow-ups either with an echo or another cardiac MRI. If you have the full report of the MRI, I am happy to go through with you.

Thank you doctor,

What does enlarged pulmonary artery mean with velocity 1.4?

Hi,

Welcome back to icliniq.com.

It means it is dilated more than the normal size for her age. The velocity is referring to the speed of blood flow across the valve. A velocity of 1.5 m/sec tells me that the degree of pulmonary stenosis is at most is mild. The narrower the orifice the higher the speed of blood across it. If you think about it as a house with water coming from its end. If you put pressure at the open end and make it smaller the water will reach further distance because its speed increased.
