I am 22 weeks, 5 days pregnant and our baby was just diagnosed with an Epstein’s anomaly with severe right atrial enlargement 2 weeks ago (specifically, her heart takes up 86% of her chest cavity). We are being followed at the University of Iowa currently. Are there any procedures that you can perform at Mayo that are not available at places such as the University of Iowa? I had read about something called a cone procedure, what type of CHDs qualify for this and what does this particular procedure involve? We are considering seeking a second opinion at Mayo clinic.
