Once a pericardial cyst is diagnosed the patient should be scheduled for surgery as soon as possible. The surgical methods include traditional open heart surgery and thoracoscopic surgery. Pericardial cyst is a benign disease of the heart, the position of early stage is relatively fixed, the degree of adhesion is light, easy to perform surgical separation, and can be treated by small anterolateral incision for cystectomy. As the cyst expands, it will be accompanied by some compression symptoms, cardiac function abnormality, secondary infection, etc., and the surgery will be difficult and risky. Surgery is an effective treatment for pericardial cysts, although there are some drawbacks, such as the development of postoperative complications (postoperative intestinal adhesions, pneumonia, postoperative incision infection). The use of thoracoscopic surgery to treat pericardial cysts is also gradually favored by patients, with the advantages of less trauma and higher quality. It is recommended that patients with pericardial cysts should go to the hospital in time. The doctor will make a reasonable choice of treatment according to the degree of the patient’s disease.
