Unexpected traumatic rupture of left atrium mimicking aortic rupture.
Left atrial (LA) rupture is rare following blunt chest injury. We describe a case of blunt LA rupture that was treated surgically. This report is intended to alert practitioners for a need of a close multiple disciplinary collaborations among them for optimal management of patients with this type of trauma; because other non-cardiac injuries involving the head, abdomen, or extremities are considered covariates for in-hospital mortality. As in the present case, the patient eventually died from associated extrathoracic injuries. The diagnosis of LA rupture is by exclusion. However, the initial radiological reading may be misinterpreted, because this injury can easily be mistaking for an aortic rupture. The final reappraisal of the chest imaging studies should be interpreted by a skilled radiologist to avoid misdiagnosis. Subtle radiological features can help distinguish aortic thoracic injury as illustrated in this patient. These factors may be useful to the practicing surgeon in deciding surgical approach.
