  On the day of the operation, the various discipline teams of the First Affiliated Hospital of Xi'an Jiaotong University collaborated.

The cardiovascular surgery team successfully completed the aortic valve replacement + right ventricular diverticulum repair. Then, the thoracic surgery team relayed the effort to repair the absent chest wall with a fully prepared artificial sternal rib prosthesis, realizing the functional reconstruction of the bony thorax.
