Parents are anxious when their child has a heart attack. They want to find the best hospital and the best doctor to operate on their child immediately. But as a person who does not know much about medicine, especially about heart surgery, it is not easy to choose the right doctor. I have a few suggestions here for your reference: 1. Check the internet to see where you can do heart surgery, and pay attention to the number of surgeries this hospital per year, generally the quantity is more, then there is quality. 2. Among the doctors you can choose from, select a few with certain years of experience and contact them. Feel the attitude of the person who gives you the answer, and feel if he is the doctor you are looking for. 3. Look at his contact records with other patients to get a feel for them again. 4. Contact the families of the patients he has treated to see how satisfied they are. 5. Make a decision and schedule a time.
