Patient: Description of condition (onset, main symptoms, hospital visited, etc.): At the time of the two-month checkup, the doctor detected a heart murmur and went to the Women’s and Children’s Hospital for a heart ultrasound. The doctor said that the arterial duct is not closed and the soft round hole is not closed. The doctor said the heart still had a murmur when I went for a vaccination checkup at three months, and I took polio pills at two months, but at three months, the doctor wouldn’t let me take the pills and wouldn’t give me polio shots for fear that it would affect me. Can I get the vaccination in this condition? It’s urgent! Doctor: Congenital heart disease usually does not affect vaccination, and vaccination can be given as usual. Patient: Examination: AOD:12mm, LAD:15mm, LVDd:23.6mm, IVSTd:5.6mm, LVPWTd:5.2mmEF:59.8%, FS:30.1%, E:99.3cm/s, A:75.0cm/s, HR:138 beats/min, normal size of each atrium, no wall thickness, no movement No abnormalities were seen. The width of the foramen ovale was 2.3 mm, CDFI: left-to-right shunt was seen. The aorta and pulmonary artery had normal internal diameters, good aortic amplitude, and repetitive waves were present.CDFI: a shunt bundle was seen between the descending aorta and the pulmonary artery. CDFI: A small amount of blue regurgitation was seen in mitral systole. pW: The E peak of the diastolic flow spectrum of the mitral orifice was greater than the A peak. Ultrasound impressions: 1. unclosed ductus arteriosus 2. unclosed foramen ovale Doctor: unclosed ductus arteriosus can be cured by interventional therapy until the child is 6 months old. Patient: So is it possible to follow the normal vaccination? Doctor: Absolutely.
