Echocardiogram results mitral valve: mild insufficiency and tricuspid valve: very mild insufficiency. should i be referred to cardiologist?

Not really: These are not clinically important and are commonly seen in normal people on echocardiogram.

No: Mild valvular insufficiency is common and does not cause problems. It may be worth periodic echocardiographic follow up to ensure the valves do not get worse and ensure timely intervention if the insufficiency is worsening. Any follow-up should be discussed with your doctor.
