Hello Andy, most commonly pericarditis and myocarditis is idiopathic or viral induced. Most often these get resolved with no permanent damage.In your case as MRI itself says that EF is 66%, which indicates that there is no permanent injury.i think post this result your steroids or colchicine must have been stopped. I think there is nothing to worry as of now. Continue the medication as per clinical consult .
