Tetralogy of Fallot is the most common complex preconditioning disease, and it is also the most mature and effective complex preconditioning disease to be treated surgically. Currently, there are about 500 radical surgery cases of Tetralogy of Fallot in our hospital every year, and the surgical mortality rate is less than 1%. However, due to the disease, the surgery requires reconstruction of the right ventricular outflow tract structure, resulting in varying degrees of postoperative pulmonary valve regurgitation. The pulmonary valve is like a door, and when the door is small and the door frame is large, it inevitably results in the door not closing tightly, creating a result similar to regurgitation. As the child grows older and more active, pulmonary regurgitation increases and the right ventricle enlarges. Right ventricular enlargement is like blowing up a balloon, which keeps getting bigger and bigger and can be retracted in a certain range, but to a certain extent it cannot be retracted to its original size or even ruptured and cannot be repaired. Therefore, the early stage of right ventricular enlargement is the compensatory stage, which usually does not show obvious symptoms, while after the compensatory stage, it turns into the decompensatory stage, and gradually arrhythmias, heart failure, and decreased activity tolerance appear. Once the compensated period is over, even intervention is very costly, bringing pain to the child, economic burden to the family, and even irreversible end such as death. A foreign study on the average follow-up of patients for 20 years after surgery showed that their long-term survival rate is about 90%, suggesting that there is still a high rate of death in the long term after surgery for tetralogy of Fallot, so parents cannot rest on their laurels after surgery. Currently, patients routinely come for follow-up at 3 months, 6 months, and 1 year after surgery, but after that they are reluctant to continue follow-up because the patients are in good condition, ignoring potential complications. Moreover, in view of the national situation in China, many patients do not have regular follow-ups due to various reasons such as economy and transportation, resulting in poor surgical results or even sudden death due to the problems of the child not being detected and treated in time. Patients need parents and themselves to pay attention to the issue of regular follow-up after surgery and timely review such as electrocardiogram and cardiac ultrasound. Through this series of examinations, we can detect potential problems of patients early and avoid complications, although there may be no obvious symptoms and discomfort. Therefore, we urge parents with precordial disease need to pay attention to regular follow-up, especially if the ultrasound has suggested moderate to severe pulmonary regurgitation or more, they should come to our hospital for review as soon as possible. At present, our hospital provides great convenience for post-operative patients with tetralogy of Fallot, and we have a special post-operative follow-up team to solve the problems of parents and patients in a timely manner, so as to protect the healthy growth of children. If you or your child has undergone radical surgery for tetralogy of Fallot, especially patients who have had more than moderate pulmonary regurgitation and need to be reviewed, you can contact our follow-up team (Dr. Chen’s cell phone number: 13522495037, you can add WeChat, you can text or WeChat or phone the specific situation during working hours, and you will be contacted promptly after seeing), so that it is convenient for you to review and make an appointment for examination in time to shorten The examination time, but also can facilitate the appointment of Li Shoujun, director of the clinic every Monday, so as to obtain expert advice. For the healthy growth of our children, let us doctors and parents join hands to pay attention to the post-operative period, follow up regularly, solve problems in time, improve the quality of life, and let our children grow up healthy and happy. Can the radical treatment of Tetralogy of Fallot be done once and for all? Tetralogy of Fallot is the most common complex congenital heart disease. With the advancement of surgical technology, there are already many patients after radical surgery, and some of them gradually develop a large amount of regurgitation in the pulmonary valve, which in turn leads to a decrease in cardiac function, etc., manifested as easy fatigue, decreased mobility, and arrhythmia. However, many patients and their families do not pay attention to regular review of the heart. However, if they miss the best time for treatment, they face irretrievable health. Therefore, in response to this situation, experts at Fu Wai Hospital urge patients after radical surgery for tetralogy of Fallot to undergo regular review, including cardiac ultrasound, electrocardiogram, chest X-ray, etc.
