On August 3, a 2-year-old girl aged 9 months recovered from a successful percutaneous balloon dilatation of pulmonary stenosis performed by our Cardiovascular Medicine Department. According to the data, this is the first case in the region where this procedure was successfully performed on a child of such a young age. This also marks a new step for our cardiac interventional team in harnessing and handling high-risk procedures. The girl, from Du’an County, had been suffering from congenital heart disease since childhood and had been treated unsuccessfully at the local hospital for several times. One month ago, the child’s symptoms worsened, and the parents sent her to our cardiovascular medicine department for further treatment on July 28 after making many inquiries. After detailed examination, the physicians of the department clearly diagnosed the stenosis of the left and right pulmonary artery branches and the failure of the foramen ovale. Pulmonary artery branch stenosis is a relatively rare congenital heart disease. On August 1, Dr. Wang Mengjie, deputy chief physician of the department, and Dr. Wu Xubin successfully performed “percutaneous pulmonary artery stenosis balloon dilation” on the child. “After the operation, the child recovered as normal. In recent years, the department, under the leadership of Vice President and Director of Cardiovascular Medicine Lin Yingzhong, has actively carried out various new technologies and achieved success, especially in interventional surgery, which has relieved the pain of the majority of patients.
