There is no clinical term for Eisenmenger syndrome, which mostly refers to Eisenmenger syndrome, and patients are usually not candidates for heart replacement. Eisenmenger syndrome is caused by a variety of left-to-right shunting congenital heart disease, and the typical symptoms of patients include cyanosis, palpitations (rapid heartbeat, often accompanied by panic), and pestle-like fingers (toes). Generally, Eisenmenger syndrome is not suitable for heart replacement or correction of cardiac malformations through surgical treatment or interventional therapy, because the survival rate and prognosis after surgery are relatively unsatisfactory and should be taken seriously. Usually, the prognosis of Eisenmenger syndrome is poor, but for patients who actively cooperate with the doctor’s treatment, the survival time and quality of life can be prolonged to a certain extent. In daily life, patients should pay attention to avoid strenuous exercise and follow the doctor’s instructions for home oxygen intake when hypoxia occurs. Some patients also need to be vaccinated with influenza vaccine and pneumococcal vaccine to prevent respiratory infections. Patients with Eisenmenger syndrome are advised to adjust their mindset and actively cooperate with their doctors for treatment, and should also seek regular medical checkups in order to monitor their physical condition.
