Mild valvular insufficiency is categorized as mitral and aortic valvular insufficiency, which is usually asymptomatic and does not require treatment and regular review. In mitral valve insufficiency, a portion of the blood flow from the left ventricle per beat will flow back into the left atrium. When the insufficiency is only mild, it is usually asymptomatic and can remain asymptomatic for a lifetime, but it should be reviewed regularly to prevent the insufficiency from worsening. In addition, emphasis should be placed on the prevention of rheumatic fever and infective endocarditis. In aortic valve insufficiency, diastolic aortic blood flow regurgitates into the left ventricle. In mild insufficiency and when asymptomatic, no medical treatment is needed and follow-up once every 1 to 2 years is sufficient. If exertional dyspnea, palpitations, and discomfort in the precordial area occur, it is necessary to actively seek medical attention to prevent the worsening of impaired cardiac function.
