The prognosis of aortic valve insufficiency varies greatly according to the nature of the lesion (acute, chronic) and the degree of the lesion (mild, moderate, severe). Mild cases can last for decades, but if symptoms are obvious and not actively treated, they can seriously affect the survival period and even lead to sudden death. For chronic aortic valve insufficiency, mild cases usually last more than 20 years without surgical treatment. Once symptoms appear, the condition deteriorates rapidly, with half of the patients dying within 5 years after angina pectoris, and half of the patients dying within 2 years after severe left heart failure. For acute aortic valve closure insufficiency, mild cases can be asymptomatic, usually progressing more quickly, there may be sudden dyspnea, can not lie down, the more serious can have agitation, confusion, coma, if not timely surgical treatment, and even death due to acute left heart failure. Most of the symptoms of aortic valve insufficiency can be significantly improved by surgical treatment. Therefore, it is recommended that once diagnosed, it should be actively treated to avoid adverse consequences caused by the progression of the disease.
