Does the regurg amount return to normal after the blood volume returns to normal in humans? I do know that some bitches will have a very slight murmur for a period of time after being in season which disappears as the blood volume returns to normal, but I thought this would be more along the lines of a turbulence type murmur with no regurgitation involved. Sounds like some regurgitation could be involved even if there is no actual mitral valve disease involved. Makes me wonder if a pregnancy could worsen MVD permanently or even trigger it a bit earlier.
Since close to 50% of all Cavaliers have developed MVD by age 5 or 6 and many bitches are bred in that age category and we only check for MVD once a year--it is possible that quite a few bitches are pregnant during the beginning stages of MVD. I wonder if there could be any protective hormonal influences from a pregnancy that could offset the negatives of being pregnant while some regurgitation is present.
