Tricuspid Regurgitation

Caption

This drawing shows the mechanism of tricuspid valve regurgitation with dilation and papillary muscle (circles) displacement. The two flaps at the bottom move away from the center opening because of the dilation. When the flaps extend to cover the enlarged opening while being pulled away because of dilation, they are not long enough to cover the opening and leakage results.
