Li is a girl who loves beauty and is cool with all kinds of sports. However, during her medical checkup, the doctor heard a murmur in the chest wall with a stethoscope and suggested that she go to a major hospital for a cardiac ultrasound to clarify the diagnosis. The results of the cardiac ultrasound confirmed the medical examiner’s statement that Xiao Li did have a congenital heart malformation, but thank goodness her condition was not very serious and belonged to an atrial septal defect, a relatively mild malformation. But from the ultrasound, the blood flow in the lungs is 1.8 times that of the whole body, and the right atrium and ventricle are already larger than normal. The long-term result of such a condition, if left untreated, is damage to cardiopulmonary function. For this reason, his parents brought Xiao Zhang to the heart hospital for consultation, and after further examination, the defect was found to be 16 mm in diameter, with the circumference at a suitable distance from other important intracardiac structures for interventional treatment. The operation was performed by the attending physician himself, who made an incision of only two centimeters from the right chest wall, and then placed a blocking umbrella through a small incision in the atrial wall. The blocking umbrella accurately blocked the defect in Xiao Li’s heart under the guidance of the ultrasound probe. The ultrasound indicated on the spot that the blocking effect was very good. No extracorporeal circulation was used during the operation, and the heart did not stop, so it can be said that there was almost no damage to the heart. The surgery went well, and Li was fully awake and off the ventilator in the operating room. She was able to talk to her mom and dad when she came out of the operating room, and it didn’t hurt at all, so much so that she couldn’t believe her heart condition had been cured! The next morning after the surgery, Li was able to walk on the floor. Since Li had to take high school exams, the treating doctor approved her discharge from the hospital to go home the day after surgery, and she returned to class the third day after surgery. Many of her classmates still don’t know that Xiao Li had heart surgery.
