Ms. Wang described the child (onset time, main symptoms, changes in symptoms, etc.) condition: the child usually has blue around the mouth and the root of the nose, and when he cries the whole face is blue. Sometimes it is accompanied by shortness of breath. I would like to know if surgery can cure it? How can it be cured? How big is the risk?

The following is the hospital ultrasound: Aorta: from the right ventricular ring 10mm, sinus 10mm, ascending aorta 11mm, riding across 6mm Pulmonary artery: from the right ventricular bifurcation anterior 4.5mm, bamboo 3.3mm, crest 2.9mm, left lung 2.2mm, right lung 2.8mm Left atrium: (anterior-posterior, left-right, long diameter S/D) 10/15, 10/15, 21/24mm. EDV:3ml; ESV:1ml; EF:61%; FS:33%; SV:2ml 1. Long-axis view of the left ventricle shows: widening of the inner aortic meridian, continuous interruption and forward displacement of the anterior wall and septum, riding on the septum, with a 60% riding rate, color flow shows: systolic right ventricular shunt to the aorta. 2. Short-axis view of the great vessels shows: echogenic loss of the lower part of the septal crest, echogenicity of the broken end The size of the notch is 8 mm, and the color flow shows that the shunt is in the horizontal direction of the ventricle. 3.Multi-sectional view shows: right ventricular anterior wall thickening of 4mm, supraventricular ridge thickening of 2×3mm, turbulence in the distal right ventricular outflow tract and pulmonary valve Vmax396cm/s, PGmax63mmHG. The remaining valve thickness, elasticity and opening amplitude are not abnormal. 4.Multi-sectional view showed: two echogenic losses were seen in the central part of the atrial septum, with echogenic enhancement at the dissection end, and the lateral defect openings in the subxiphoid section were: 5mm and 1.7mm, respectively; color flow showed: two bundles of bidirectional shunts at the atrial level. 5.The right atrium and right ventricle were large, and no abnormalities were seen in the remaining heart chambers. 6. Height 47 cm, weight 3 kg, left ventricular end-diastolic volume index: 16 ml/O. 7. Aortic internal diameter at the septum penetration 4.5 mm, McGoon index 1.1. Answer: According to the echocardiographic findings provided by you, the child has congenital heart disease, Tetralogy of Fallot, and atrial septal defect (also known as “Tetralogy of Fallot”). “). This is the most common form of complex congenital heart disease, and most children can be cured surgically (although there may be some problems with long-term outcomes). However, not all children can obtain a radical cure with a single surgery, and some may require two or more surgeries to resolve. On ultrasound, children with poorly developed pulmonary arteries may require multiple surgical procedures. Regarding the timing of surgery, if the child has already had a brief episode of impaired consciousness (e.g., sudden double vision, no call) or if the lips and nail bed are more severely cyanotic, he or she may have to undergo the first surgery as soon as possible to relieve the hypoxic symptoms; thereafter, in another six months, the timing of radical surgery will be determined based on the results of the review. If the cyanosis is not too severe and no consciousness problems have occurred, the echocardiogram (also known as cardiac ultrasound) can be reviewed regularly, for example within the last 3 months, to understand the extent of pulmonary artery development before deciding on the surgical plan and timing. In general, it is safer to do the eventual radical surgery at least at 6 months of age or older.
