Insights
Acute aortic dissection can mimic acute pericarditis, presenting with ST elevation on ECG. Early recognition of this aortic dissection presentation is crucial for timely surgical intervention and improved patient outcomes.
Area of Science:
- Cardiology
- Thoracic Surgery
- Medical Diagnostics
Background:
- Acute aortic dissection (AAD) is a life-threatening condition.
- Initial presentation of AAD can be variable and sometimes misleading.
- Pericarditis is an inflammatory condition of the pericardium, often presenting with chest pain and ECG changes.
Abstract:
We herein report 3 cases of acute aortic dissection (AAD) in which the initial 12-lead electrocardiogram showed typical ST elevation consistent with acute pericarditis. All patients exhibited small pericardial effusion but did not suffer from rupture into the pericardium or clinical tamponade. Slow leakage or exudate stemming from the dissecting hematoma appeared to have caused inflammation, resulting in pericarditis. Therefore, we highlight the fact that AAD may masquerade as acute pericarditis. Physicians should be aware of the possibility of type A AAD as an important underlying condition, since the early diagnosis and subsequent surgical treatment may save patients' lives.
