It’s a regurgitation or prolapse of the mitral which is the only two leafed valve in a normal heart
Unless you’re symptomatic leave it alone
I was born with a bad heart.....a shitstorm heart but I don’t quit
What you have is essentially benign unless the prolapse gets more pronounced and you’ll be symptomatic
Tired and pallid from maybe arterial and venous blood mixing
Maybe some atrial flutter with the HIS conduction bundle getting confused
But if you feel nothing I’d quit worrying about it
Thanks for the info!
