I've just been diagnosed with aortic insufficiency. The echocardiogram report listed it as severe, and I have chest pain and fatigue. However, since my EF was 60%, my cardiologist considers it moderate. At first I considered this good news, but then realized, I'm still going to have the chest pain and fatigue. Also, since my heart is strong, wouldn't it be better to replace the valve now, instead of waiting until it gets weak? I like to exercise, and my cardiologist says I can continue, and even do a marathon, but I'm hesitant. Should I get. Second opinion?
