Effective myocardial salvage with percutaneous coronary intervention in late diagnosed acute post-traumatic ST-elevation myocardial infarction

Background: Acute post-traumatic ST-elevation myocardial infarction (STEMI) is rare but potentially disastrous in patients with blunt cardiac injury. Sometimes the diagnosis is delayed. Failed myocardial salvage by percutaneous coronary intervention (PCI) within 9 h after the onset of post-traumatic STEMI has been described. Objective: We present a case report of a patient in whom effective myocardial salvage with PCI was obtained in a late diagnosed acute post-traumatic STEMI. Case Report: We report the case of a young man who was involved in a motorcycle crash, who had a delayed diagnosis of post-traumatic STEMI. Diagnostic coronary angiography was performed to guide treatment strategy. An occluded left anterior descending artery due to a dissection, and an intimal flap at the first diagonal branch were found. A PCI was done 18 h after the onset of the event with striking and immediate improvement of the regional left ventricular wall motion and ejection fraction. Conclusion: After blunt thoracic injury, there is the possibility of an acute post-traumatic STEMI being present when facing a patient with clues of blunt cardiac injury. If the diagnosis of acute post-traumatic STEMI is clinically strong, the patient should be managed individually according to the clinical scenario. Early recognition and prompt management are vital when dealing with patients suffering post-traumatic STEMI.
