Chutian Metropolis Daily reported on January 29 (Reporter Chen Yuan, Correspondent Xue Yuan) A 13-year-old boy was thin and often suffered from pneumonia. It was actually caused by a "hole" in his heart. Experts used a "mushroom umbrella" to successfully seal the housing separation defect. Resolved cardiac crisis.

The 13-year-old boy Weiwei (pseudonym) lives in Suizhou and is a second-year junior high school student. He is very handsome. Half a month ago, Weiwei went to a local hospital for a checkup due to a cold and pneumonia. During auscultation, the doctor found some heart murmurs. Based on Weiwei's history of frequent pneumonia, he suspected that there might be a heart problem and suggested that he complete a cardiac color ultrasound examination. The results confirmed the doctor's judgment that Weiwei suffered from an atrial septal defect, with a 1.7 cm diameter hole in the left atrium.

Considering that Weiwei's heart defect is large and the location is an inferior chamber atrial septal defect, it is inherently difficult. In addition, the edge of the defect is short, and the occluder may not be successfully inserted and placed, resulting in failure of the occluder. He visited many hospitals and reported that Thoracotomy is recommended to repair the leak. Because they had concerns about surgery and wanted to give it a try, their parents took Weiwei to Wuhan Children's Hospital, where the interventional surgery was successfully performed.

Zhang Yong, director of the Department of Cardiovascular Medicine at the hospital, explained that the edge of the atrial septal defect away from the inferior vena cava is the most important in sealing and is the most important force-bearing point after the occluder is placed. Under normal circumstances, the distance from the edge of the atrial septal defect to the openings of the coronary sinus, superior and inferior vena cava, and pulmonary veins should be greater than 5 mm. Otherwise, the edge will be short and the support will be poor. The occluder will easily slip when clamped in the atrial septal defect, and Weiwei's The "hole" was less than 4 mm from the edge of the inferior vena cava.

After careful study, Director Zhang Yong believed that although the edge of the inferior vena cava was short, its thickness was acceptable, and other edge conditions were good, so there was a chance of successful sealing. After repeated communication with the patient and family, we decided to boldly try to change the placement angle of the occluder and use the pulmonary vein release method to place the occluder perpendicular to the interatrial septum.

During the operation, a delivery system with an "umbrella-shaped" occluder was accurately delivered into the left upper pulmonary vein through femoral vein puncture, perpendicular to the interatrial septum, allowing the occluder to open like an umbrella and block the 1.7 cm hole. , the mixed blood immediately "goes its own way". After only half an hour of surgery, the risk of sudden death of the child was successfully eliminated at any time. The parents' worries were finally relieved. The child suffered little damage, less bleeding, and recovered quickly. He was discharged from the hospital two days after the operation.

Zhang Yong introduced that when there is a defect in the atrial septum of the heart, an abnormal channel will be formed, connecting the left and right atria. Part of the blood flows directly from the left atrium to the right atrium through this "hole", forming an abnormal blood shunt, causing the blood flow to the body's tissues to be "in short supply", resulting in a relative reduction in the supply of oxygen and nutrients throughout the body, which will affect the child over time. exercise endurance and physical development; at the same time, the right atrium and the blood volume going to the lungs are "oversupplied", causing the right atrium to enlarge, the pulmonary blood flow increases, and the burden increases, resulting in increased pressure on the lungs, and children are prone to disease. Respiratory tract infections and pneumonia can lead to pulmonary hypertension and even heart failure over time, and may even be irreversible in some patients.

Zhang Yong said frankly that atrial septal defect is relatively hidden. Most patients with atrial septal defect have no clinical symptoms in childhood and are not easy to detect through routine physical examination. Experts remind that when a child is found to be fatigued and asthmatic after frequent activities, and his physical fitness and development are not as good as those of children of the same age, or he has repeated upper respiratory tract infections or pneumonia, parents should pay more attention and take the child to complete a cardiac color ultrasound examination as soon as possible to rule out the possibility of congenital heart disease. .
