Ten years after a cardiac open heart surgery, a second open heart surgery is usually not needed, just incise the skin and subcutaneous tissue and find the wire. Cutting and pulling it out is all that is needed. After having a cardiac open heart surgery, the wire is needed to close the sternum in order to ensure a strong suture. In most cases, the wires do not need to be removed after a cardiac open heart surgery and do not have a particular effect on the body. Therefore, if you want to take out the wire from the surgical suture site 10 years after cardiac open heart surgery, it is recommended that you go to the cardiac surgery department of a regular hospital to have an electrocardiogram, cardiac ultrasound and other examinations, X-ray examination, to make clear that there is no abnormality in the suture site, and have a professional cardiothoracic surgeon make a comprehensive judgment.
