Abstract
Tricuspid valve regurgitation (TR) is common in the adult population. A small part of this population is devoted to those who have a flail tricuspid leaflet. Flail TR can be caused by blunt chest trauma. Onset is often acute and severe and rarely seen in the form of isolated flail TR. Here, we present a rare encounter with chronic isolated tricuspid valve flail and severe TR related to blunt chest trauma.
