Innovative pediatric congenital heart disease surgery recently, at the annual meeting of the American Thoracic Surgery Association, the highest forum of international cardiovascular surgery, the first voice from the field of pediatric congenital heart disease in mainland China: Chinese Academy of Medical Sciences The report of the “Double Ventricular Outflow Reconstruction Strategy and Surgical Choice†conference read by Professor Hu Shengshou was highly evaluated among international peers. According to reports, the aorta of the normal human heart is connected to the left ventricle, and some children may have abnormal connection of the ventricular aorta, that is, the aorta and the right ventricle are "missed", and the left ventricular outflow tract stenosis is also present, which is characterized by severe hypoxia. Purpura, loss of mobility. If not treated in time, the child often died before the school age, but the common aorta transfer surgery is not suitable for this type of congenital malformation.
In April 2004, the Pediatric Cardiovascular Surgery Center of Fuwai Cardiovascular Hospital took the lead in creating a new type of surgery in the world - "Aortic Root Transposition", which simultaneously reconstructed the left ventricle and right ventricular blood outflow channel of the child. . Dr. Liu Zhigang from the center said that it is very difficult to double the transposition of the root of the aorta. The doctor should "root out" all the aorta and pulmonary artery of the heart of the child, swap their positions, and replant the coronary artery. Limit the child's own valve and collateral vessels, and truly achieve radical cure in anatomical sense. The reconstructed blood channel and the valve and other tissues grow with the growth of the child, which can avoid secondary surgery to the greatest extent and improve the quality of life of the child. As of April this year, 20 consecutive cases of correction surgery in Fuwai Hospital have been successful. ——Midi Medical Network
