Patient: On May 7, 2012, a heart murmur was detected at a physical examination at the Maternal and Child Health Station at the age of 2. Usual physical examination was normal. No adverse symptoms were found in life. An echocardiogram was done at Anhui Provincial Hospital to detect this disease. The main measurements are: aortic internal diameter 17 mm left ventricular diastolic internal diameter 36 mm septal thickness 6 mm left atrial internal diameter 24 mm left ventricular end-systolic internal diameter 26 mm left ventricular posterior wall thickness 6 mm. Examination: 2D: The aortic internal diameter is not wide, and the valve morphology, echogenicity and opening/closing are acceptable. The left heart is large and the right heart is not large. The septum and posterior wall of the left ventricle are not thick, with anisotropic motion and moderate motion. The inner diameter of the main pulmonary artery was thick (14 mm), and the distal bifurcation of the main pulmonary artery was seen to the left of the descending aorta, with a 3.4 mm diameter. The pulmonary valve and mitral and tricuspid valves had fair morphology, echo and opening and closing. No significant echogenic loss of atrial and ventricular septum was seen. Color: A multicolored shunt bundle with a PG of 72 mmHG was seen in the main pulmonary artery entering the descending aorta via the above-mentioned tubular traffic and traveling along the lateral wall. No significant abnormal flow signal was seen in the cuspidal orifice. Left heart function measurements: FS: 29% LVEF: 56%. The mitral orifice antegrade flow E peak〉A peak. Diagnosis: congenital heart disease: arteriovenous ductus arteriosus (tubular type) No treatment Want to confirm when to operate? What type of surgery? Which is the best method: open ligation or vein blockage! Li Lei: 2 years old, 3 mm ductus arteriosus, no need for open heart surgery. The vast majority of unclosed arterial ducts are blocked by intervention of an internist. We recommend recent treatment Patient: Is the interventional blockage permanent? Will the blockage come off later due to the child’s high activity level? Also, will the radiation used during the blockage have any effect on the child’s physical development? Will it damage the child’s blood vessels and cause a hemolytic reaction when it enters? Where is the best place in the country to do it now? Thank you, Lei Li: For specific questions about the intervention, you can consult with a pediatric cardiologist. Director Guo Baojing is recommended. Patient: Why don’t you suggest a small surgical incision for treatment? We think this is the most thorough way! The MRI can’t be done after the metal is put into the body! Is there any effect on the baby’s development when there is radiation exposure during the intervention? Is there anything wrong with the surgical incision other than a scar? Li Lei: Why do you want to do an MRI? Everyone in your family, has everyone done it? I am a surgeon and I suggest you do intervention. What do you think, for what? Patient: We just thought the surgery was a little more thorough. We don’t want to put something inside our body and be afraid all day long! Maybe we are too conservative in our thinking! We want to put safety first! Li Lei: Arterial catheterization, the world is to do interventional blockage, you want to give your daughter open-heart surgery, in order to yourself do not have to “worry about”. Has been sick for two years, has been so? Patient: Can we call to talk about the child’s condition? There is my phone number above. You call me and I’ll call you back! Patient: It’s not an open chest left underarm incision incision of about 5 cm. My family just found out a few days. Recently struggled with what surgical method to take! Li Lei: no treatment, the safest. Open chest, much more risky than intervention. This surgery, for many years, is not done on children with similar conditions. Occasionally a parent like you, requesting open-chest surgery, for doctors who are already technically rusty, the risks can be known. Li Lei: Our center, more than 2,000 precocious heart disease surgeries a year. Despite the fact that patent ductus arteriosus is a common disease, no more than 5 cases of patent ductus arteriosus are treated by open-heart surgery. The need for the disease is paramount. The treatment method is not determined by the “fear” of parents. Patient: Does the radiation exposure during the interventional blocking process have any effect on the child? Lei Li: Consult with pediatric cardiologists, who are exposed to radiation all day long.
