“…Although uncommon, when valvular injury occurs due to blunt chest trauma, the aortic valve is most often affected, followed by the MV and TV 3,5,6 . Consistent with the uniqueness of this case, only four patients of simultaneous complete papillary muscle rupture of the MV and TV have been previously reported 5,7–9 . In addition, this case report highlights the importance of early assessment by TTE and TEE in patients admitted with blunt chest trauma.…”

Cardiac injury, specifically valvular rupture, must be considered after blunt chest trauma even in previously healthy patients. Isolated mitral regurgitation (MR) and tricuspid regurgitation (TR) due to blunt chest trauma are rare phenomena. More unique is simultaneous complete papillary muscle rupture of the mitral valve (MV) and tricuspid valve (TV) with only four patients being previously reported in the literature. This case describes a patient with complete transection of the posteromedial papillary muscle of the MV with severe MR and a concomitant flail TV with severe TR following a motor vehicular accident. The importance of transthoracic and transesophageal echocardiography in the early evaluation of patients following blunt chest trauma is also highlighted by this case.

“…6 The reason that clinical cases are rare is that survival from trauma of sufficient severity to cause valvular injury is thought to be unlikely. 8,9 The mechanism of traumatic atrioventricular valve injury is most likely compression of the ventricle(s) between the sternum and spine coincident with isovolumetric contraction with a consequent supranormal increase in intraventricular pressure against closed valves. 6,8 The papillary muscles are the most commonly affected component of the mitral valve, with resultant valvular regurgitation.…”
