Some examples from aortic and bicuspid regurgitation (insufficiency), but similarities can be drawn to tricuspid insufficiency / regurgitation:

E.g. "Patients with multiple or diffuse regurgitant jets were excluded, and the value of VC-W with these jets cannot be determined." (ref: http://www.circ.ahajournals.org/cgi/content/full/102/5/558)

E.g. "We describe a patient with chronic aortic regurgitation and moderately severe left ventricular dysfunction whose echocardiographic study revealed striking clouds of smokelike blood billowing in discrete puffs from the area of the mitral inflow tract toward the cardiac apex early in each diastole."
