Background
Blunt chest trauma (BCT) presenting to the emergency department is common and may cause life-threatening cardiac complications. Whilst complications causing haemodynamic instability are generally detected promptly, others may present late with long-term consequences. We describe a rare, serious complication of BCT presenting five years after a road traffic accident (RTA).
Case summary
A 23-year-old man was incidentally found to have a murmur. Past history was notable only for BCT with rib fracture sustained in a RTA 5 years prior. Examination revealed a hyperdynamic pulse, loud decrescendo diastolic murmur, and Duroziez’s sign over the femoral arteries. Echocardiography showed severe valvular aortic regurgitation (AR) from a hole in the left coronary cusp and holodiastolic flow reversal in the descending aorta. The left ventricle (LV) showed marked dilatation in diastole, mild dilatation in systole, and preserved systolic function. The aorta was normal. Severe AR was attributed to his previous BCT, with AR causing subsequent LV dilatation. He underwent aortic valve replacement (AVR) with rapid recovery. He remains well, and his echo shows a well-functioning AVR with normalization of LV dimensions.
Discussion
Aortic regurgitation following BCT is rare but well-recognized, most often resulting from RTAs. Only a third of cases are diagnosed acutely. In others, lack of haemodynamic instability means that emergency echocardiography is not routinely performed, such that this may go unrecognized with long-term consequences. Clinicians should be aware of possible valve damage following BCT. Prompt echocardiography should be routinely performed for all BCT at initial presentation, even without haemodynamic instability. |
