Hi, I'm A 17 Year Old Female With Ebstein's Anomaly.

Hi, I'm a 17 year old female with Ebstein's Anomaly. In the past 6ish months, I've been experiencing increased fatigue, lowered stamina, and find it hard to catch my breath. I am not an out of shape person, for I play soccer year round and run on my off time. There shouldn't be a reason for me to be this easily winded, yet I'm finding it harder and harder to exercise. Would it maybe be a sign that I need my valve fixed/replaced? I see my doctor in a couple of months, but should I be prepared to discuss surgery with him?
