The general treatment after cardiac mucinous tumor surgery is the same as other cardiac surgeries, but cardiac mucinous tumor surgery should pay attention to whether the patient presents with evidence of tumor embolism. If a patient develops a limb embolism after surgery, appropriate treatment should be actively taken to prevent further deterioration of the condition. At the same time, blood volume should be replenished, and the use of drugs to strengthen the heart, diuretic, and adjust blood pressure is also a top priority in the postoperative care and maintenance of cardiac mucinous tumor. If circulation is affected, aortic balloon counterpulsation or left or right ventricular assisted circulation can be used if necessary. If the patient develops some degree of arrhythmia, it can be relieved by correcting electrolyte imbalance, using appropriate antiarrhythmic drugs or installing a temporary pacemaker. In patients with cardiac mucinous tumors, the ability to judge the condition needs to be improved to ensure that follow-up is required. It is important to detect the first signs of recurrence early, and one of the most important screening techniques, in addition to self-perceived signs and symptoms, is an echocardiogram. Patients who have undergone cardiac mucinous tumor surgery should be reviewed every six months for four years after surgery and annually after four years to ensure that the relevant organs are functioning properly after surgery. Patients face a very serious risk of recurrence after surgery and need long-term follow-up. If possible, they can return to the hospital where the surgery was performed for follow-up to ensure their health after surgery.
