If there is no clinical manifestation of 24-year-old patent foramen ovale, regular observation is recommended. However, once symptoms such as dyspnea or palpitations occur, right-to-left shunting occurs in patent foramen ovale, which can lead to cerebral infarction or transient ischemic attack Interventional occlusion is needed, which is more serious and requires surgical treatment as soon as possible. Foramen ovale not closed means that the foramen ovale is still not closed at birth. It is a congenital heart disease and is relatively common in adults, usually without any clinical symptoms or discomfort, and does not require special treatment. Therefore, at the age of 24, an unclosed foramen ovale is not serious as long as there are no obvious symptoms or discomfort. If the unenclosed foramen ovale is accompanied by dyspnea, palpitations, and the presence of a right-to-left shunt, prompt surgical treatment is required. Whether or not a 24-year-old foramen ovale is serious depends on the degree of foramen ovale, whether or not there are clinical symptoms or discomfort, etc. It is recommended to go to a regular hospital to improve the systematic examination and diagnosis, and then determine the next step in the treatment program, and if necessary, consider surgical treatment. Usually, we should pay attention to keep warm and avoid colds, so as not to cause viral myocarditis. Specific diagnosis and treatment should follow the doctor’s advice.
