I would suggest a second opinion especially that you are getting more fatigued. EF's are reported by the reading physician not by the machine. The latter is usually very incorrect in assessing EF because it only looks at one frame. I would say that if your EF is close to 55% that you should ahve your surgery soon.
Thank you for your reply. I also had asked why was my EF was reported as 55-65%. Is it normal to give such a large range like this? If my EF was at 55%, then that would mean that I should have surgery soon, especially with the severe regurgitation. But if my EF is 65%, then that would be fine. Is this normally done -- it sure creates a level of confusion.
I also thought that EF was based on a formula (EDV-ESV = stroke volume. Then the stroke volume is divided by EDV = Ejection Fraction).
Is it done calculated that way? I didn't know it was based on visual. One person might view it differently than another. How can that be accurate? I apologize for the question again, but I remain somewhat confused. I appreciate your help.
