mitral valve regurgitation

I had an echo cardiogram Thursday 7/11 and don't have my appointment with the cardiologist until 7/24. This is the result on my mitral valve. It has been 2+ for a long time and suddenly changed. I am having symptoms including shortness of breath when laying down (it wakes me at night, swelling in my feet, slight chest pain, extreme tiredness and fatigue. I sent a Mychart message to my doctor and got an auto-reply that it could take up to 9 business days to get a response. Is this considered a medical emergency?
