Flail tricuspid valve in a patient with history of stab chest wound

Cardiac sequelae of stab chest wounds may be various and dramatic, and the right ventricle is the most commonly injured chamber. Correct diagnosis of cardiac damage may be done up to many years after the trauma. We describe a rare case of isolated, unexpected flail tricuspid valve detected by transthoracic echocardiography in a young patient with remote history of stab chest wound.
