Mild tricuspid valve insufficiency is often a finding on a cardiac ultrasound that suggests the presence of mild tricuspid regurgitation. Most cases of mild tricuspid insufficiency are asymptomatic and often occur as a result of pulmonary hypertension. Pulmonary hypertension can occur in diseases related to the left heart system or in diseases of chronic pulmonary origin. Chronic thromboembolic pulmonary artery disease can also lead to pulmonary hypertension, and idiopathic pulmonary hypertension, among others, can lead to mild tricuspid valve insufficiency. Mild tricuspid insufficiency is often indicative of right heart overload and right heart hypertrophy, and can be treated with diuretics in patients with right heart failure.
