Currently, there are two main routes for interventional occlusion of precordial disease: percutaneous (using radiation or ultrasound guidance) and transthoracic (with an incision in the chest). There is a growing concern about the possible effects of the interventional occluder itself on the patient. The first is the psychological impact, which may not be significant for the child, but in the future, when you grow up, whenever you go for a chest X-ray or a fluoroscopy or go through a security check, there will be a metal image that will remind you that you were a patient with a preexisting heart disease. You are different from others. I remember a colleague who had orthopedic surgery and had a metal nail in his body, and every time he went through security, it was a pain in the ass. Each time, he had to explain to get it out, and then he endured the pain and went to the hospital to get the nail out. The blocker itself is an alloy material. Will it alarm when the security check is sensitive?

But once you encounter very harsh conditions, it’s hard to say. “A thousand miles without a needle”, a person carrying a school bag, the bag is lighter, if it is a hike, it will also be affected. Then there is the blocker of the heavy metal itself will not release metal ions, it is not easy to say, there are already suspicions and reports abroad. The blocker can work solely because the metal structure is compressed and finally eroded into the tissue. The final result of the erosion is not known at the time of the surgery. I have personally encountered several cases where the blocker eroded the aorta leading to rupture, the tricuspid valve leading to tendon rupture and incomplete closure, and the ventricular septum leading to conduction block. Of course, there are some advantages to percutaneous occlusion without a chest incision. Although it may cause damage to the arteries and veins of the legs. The advantage of using a chest incision is not obvious to me, because the incision is not much smaller than the small incision I made.
