Wheezing and chest tightness after heart valve surgery is considered to be due to the patient’s own circulatory problems on the one hand, and inflammation on the other. 1. As the patient was in prolonged heart failure before the operation, it takes some time for the heart function to recover, and symptoms such as wheezing and chest tightness may occur during the recovery period. 2. Consider aseptic inflammation arising from the increased demand for circulatory volume during surgery. 3. There is also inflammation triggering interstitial exudation of the lungs causing edema, which in turn triggers symptoms such as chest tightness. In conclusion, postoperative cardiac function requires a certain amount of time to recover, if the symptoms are mild, they should be observed first, and if symptoms such as chest tightness and shortness of breath gradually worsen, they should consult a doctor in time for further examination according to the doctor’s professional guidance.
