The patient was a one-month-old infant who was discovered to have an abnormality in the anterior chest wall shortly after birth. Specifically, there was a pronounced depression in the midline of the upper chest wall where the protection of bone structures was noticeably absent. The infant was diagnosed with sternal cleft and congenital heart disease. Due to the infant's poor health, surgical intervention has been postponed temporarily. Over time, the infant's condition gradually worsened, resulting in breathing difficulties and triggering a lung infection.

There is a noticeable depression in the center of the chest wall, accompanied by obvious paradoxical respiration. This area shows large-scale deficiency or absence of bone structures, with only about 1 cm of bone structure remaining at the inferior end of the sternum, connecting both sides of the chest wall. Additionally, the patient suffers from congenital heart diseases, including ventricular septal defect and patent foramen ovale, which have led to abnormal heart rhythms and sinus tachycardia.
