Tricuspid insufficiency (TI) , a valvular heart disease also called tricuspid regurgitation (TR), refers to the failure of the heart's tricuspid valve to close properly during systole.eft ventricular failure is, in turn, the most common cause of right ventricular dilation. Other common causes of right ventricular dilation include right ventricular infarction, inferior myocardial infarction and cor pulmonale. Other diseases can directly affect the tricuspid valve.
