Hi there ~
Although it is hard to decipher what you have written in short phrases, I think what you are asking is if you need an echo now since you think that the symptoms are related to your heart murmur
. I am sure your cardiologist has assessed you for the same and reviewed your records, however it might be better to go over it again with your cardiologist to allay your anxiety
about your worsening condition being related to your heart murmur. A second opinion
about this issue might also be helpful.
I hope this helps. Take care and have a lovely day!
