Hi all!
I am 3 months post op with a St. Jude valve. I am having a lot of BP issues; possibly hormonal, so doing the tests. I had an echo done yesterday and was told I have mild regurgitation. Is that normal with a new valve? I will be discussing with my cardiologist at next appointment. Thank you.
 
Yes a mild regur. Is common. It’s known for washing the valve . But however one more echo in 4 to 6 months will be helpful
 
My understanding is that even good, natural valves, have a bit of regurgitation.

Prosthetic valves don't completely stop regurgitation - as far as I know. If you have a small amount of regurgitation and your doctor isn't particularly concerned, you probably shouldn't be, either.
 
Regurgitation 101:

All mechanical valves have a certain amount of regurgitation (reg), reg can be described as fluid going "the wrong way", or not forward flow. This is normal for a mechanical valve. There are two components to reg:

1) leaflets closing - fluid pushed "the wrong way" (backflow) by the sweeping action of the leaflets and
2) leaflets closed - clearances between the leaflets and the orifice allow for leakage - the higher the (blood) pressure the more the leakage.

Backflow + leakage = regurgitation

Large valves (31mm) have more reg than smaller (21mm) valves.

A few thousands of an inch (0.001) variation between leaflet(s) and orifice can have a significant effect on leakage volume and the manufacturers control this.

Tissue valves for the most part do not leak although they still have backflow.

Reg is measured in ml per pulse or % of stroke volume.
 
Useful thread, thank you. 6 years in diagnosed with mild regurgitation. Message from Dr is to lose some weight, less strain on the heart and lower blood pressure. Message received! 11kg adjustment planned by Christmas 2023. JCG
