Traumatic tricuspid regurgitation (TR) and congenital pericardial defects are rare conditions, there being fewer than 200 recorded cases of each. Here we describe the interesting case of a patient with traumatic TR due to rupture of chordae tendineae in association with a congenital pericardial defect. We suggest that the association of traumatic TR and congenital pericardial defect has a high probability of occurrence. We hypothesize that traumatic rupture of valvular structures occurs readily in patients with congenital pericardial defects.
