Papillary muscle dysfunction due to intramyocardial haemorrhage should be considered in the differential diagnosis of traumatic mitral insufficiency, especially in potential cardiac donors.

Requires caution assessing mitral valves in blunt trauma donors; leaves open the prevalence of intramyocardial haemorrhage as a reversible mechanism.
A previously healthy, x8-year-old man was transferred to Stanford Medical Center as a potential cardiac donor 20 hours after suffering severe head injury. Because of a systolic heart murmur, left ventricular angiography was performed and showed obvious mitral insufficiency. At necropsy the heart was normal except for haemorrhagic necrosis within the tips of the mitral papillary muscles. Thus, papillary muscle dysfunction due to intramyocardial haemorrhage must be added to the differential diagnosis of traumatic mitral insufficiency.

Schroeder et al. (1972) conducted a case report in Papillary muscle dysfunction due to non-penetrating chest trauma (n=1). Non-penetrating chest trauma was evaluated on Mitral insufficiency and papillary muscle dysfunction. Non-penetrating chest trauma caused papillary muscle dysfunction due to intramyocardial haemorrhage, presenting as mitral insufficiency in a potential cardiac donor.
