Mild pulmonary stenosis and regurgitation with mild pulmonary hypertension

[swaryrajan]

Hi everyone...i really need your help in answering my questions and sharing your experience for those who have the same diagnose..i had PDA when i was born and corrected when i was 1year old.Later on i was told that i have pulmonary stenosis and regurgitation which is mild. Now, im 21years old. Recently, when i went for my echo and follow up. i was told that i have mild pulmonary hypertension with the pressure of 30...So, does this mild pulmonary hypertension develop fast? Usually how long it takes to go severe? Or does it remain the same forever? Did any of you had a mild HPT and become severe within few years?

Thanks alot for you comments...!

There isn't typically a change in pulmonary stenosis (even in moderate cases) it is well tolerated.   Again the diagnosis of pulmonary hypertension in the presence of pulmonary stenosis is not accurately diagnosed from a TTE.    In fact there is quite a margin of error in some studies where as the pulmonary pressure is indeed normal when using a catheter method.

All of these concerns should be directed towards your OB/GYN as they know all of the background.   Pulmonary stenosis is typically a benign condition that doesn't progress and patients live a normal life expectancy-- it is only when severe that it may require intervention.

You have to understand the mechanics of pulmonary stenosis and the method of measurement of pulmonary pressure (from the Tricupisid jet)   It has been very well documented that pulmonary pressure can't be estimated when pulmonary stenosis is present without right-heart cath.   The reason is the pulmonary valve creates a pressure increase which artificially inflates the pressure through the tricupsid valve.    This process emulates what would be pressure in the pulmonary artery (but is created from the valve itself)  

So the basic rule:  No estimate of pulmonary pressure can be done properly in anybody with pulmonary stenosis (I have PS as well)  I have done alot of research into this.   The cutoff for PH is 35 mmhg anyways without right heart/atrium enlargement.

Pulmonary stenosis is usually benign even in moderate cases-- Pulmonary regurgitation is seen is a normal varient as well.

I have had HPT (mild for years) and no advancement.  The underling cause can be pulmonary artery thrombosis and/or lung emboli (blood clots).  And sometimes it can be the pulmonary valve narrowing of the opening (stenosis). When  serioujs if it ever advances is chronic cough, shortness of breath, and frequent respiratory distress.

Your doctor whould be able to inform you of the prognosis as (s)he has your health history, concomitant illness, medication,  etc.  

Thanks for your questions and if you have any further questions or comments you are welcome to respond.  Take care,
