Xing Quansheng, Children’s Heart Center, Qingdao Women’s and Children’s Health Care Center: Hello! Your child’s diagnosis is basically clear: congenital heart disease, atrial septal defect, which requires surgery. However, further cardiac ultrasound is required to clarify the location and size of the defect in order to choose the treatment method, which needs to be done by a more experienced hospital and experienced doctor for you. You can choose from: surgical repair, medical interventional sealing, and surgical minimally invasive sealing. If the atrial septal defect is in the right location and size, medical interventional sealing treatment is recommended. Now is the right time for surgery and you cannot delay too long. All costs are about 25,000 yuan. Patient: Description of condition (time of onset, main symptoms, hospital visited, etc.): Patient: female, now 5 years old. At present, her body is developing well, her height is 116cm. At the age of 4, her cardiac ultrasound findings are: normal internal diameter of the aorta and pulmonary artery, good amplitude of the main wave of the aorta, the presence of repetitive waves, normal morphology and size of each atrial cavity of the heart. There were no obvious abnormal echogenicity in each heart valve. The echogenic interruption was seen in the middle of the atrial septum, with enhanced echogenicity at the severed end, and the diameter of the defect opening was about 6 MM. The septum and the posterior wall of the left ventricle were not thick and showed retrograde motion. Color Doppler showed: red predominantly colored flow bundles were seen, shunting from the left atrium to the right atrium. A small amount of multicolored interphase flow was seen at the pulmonary valve orifice in diastole, returning to the right ventricle from the main pulmonary artery, and a small amount of multicolored interphase flow was seen at the tricuspid valve orifice in systole, returning to the right atrium from the right ventricle. Spectral Doppler showed that the maximum shunt velocity at the atrial level was about 112 CM/S in diastole, the maximum regurgitant velocity under the pulmonary valve was about 187 CM/S, and the maximum regurgitant velocity over the tricuspid valve was about 206 CM/S in systole. ascending aortic internal diameter 16 MM left atrial internal diameter 27 MM left intraventricular diameter 34 MM interventricular septum 6 MM left ventricular posterior wall 6 MM main pulmonary artery internal diameter 15 MM right atrial internal diameter 26 MM right The ejection fraction is 66%, short-axis shortening rate is 35%, and the volume per beat is 31 ML. When is the best time to operate? Are there any other tests that should be done to determine the shape of the defect? Thank you! Please give me more details.
