The overall prognosis for patients with patent foramen ovale is good, with only a few cases having a poorer prognosis due to late progression without timely treatment. Foramen ovale is a relatively common congenital heart anomaly. Most patients are asymptomatic, while a small number of patients may experience unexplained strokes and migraine headaches. The overall prognosis for this disease is good, and most patients are cured with aggressive treatment. When the disease is asymptomatic, no treatment is needed, but when venous thrombosis is present and right atrial pressure is elevated, active treatment is needed to avoid stroke or peripheral arterial embolism. Its treatments include medication and surgery, commonly used medications include warfarin and aspirin, and the mainstream surgical method is patent foramen ovale occlusion blockage. Patients should pay attention to rest in daily life and closely observe their condition. If symptoms such as palpitation, dyspnea, chest tightness and fatigue occur repeatedly after exertion, they should consult a doctor and actively cooperate with the physician’s treatment.
