To ask how many procedures the surgeon has done before. As it turned out, I lucked out. Dr. John Clark who practices at a large children's hospital has done over a thousand of these procedures but I could've ended up at a hospital with someone who had much less experience. There are approximately 180 pediatric electrophysiologists in the United States, which means they all know each other and the quality of each other's work. Make sure you ask how many procedures your surgeon has done.
How long has he/she been at the hospital where the procedure will be done? What is his/her success rate? How many times has he/she had a complication? What were the complications? If the your doctor's success rate is low and his/her complications high, find another doctor. More about the procedure itself. What is my child going to go through to have this done? What can I expect? What are they going to feel, if anything? How is the surgery done? What are the potential complications? How long is the recovery period?
That it is important to choose a surgeon who is comfortable using cryo-ablation. Because more often than not, a doctor can't be certain of what he'll find in a child's heart until he gets into it. And if the surgeon discovers the problem is in the middle of a child's heart, rather than the outside, I, as a parent, would want to know that he is comfortable and proficient using cryo-ablation because of its "protective nature of the heart's normal wire," Dr. Clark said.
