Insights
Recognize 5 catheterization laboratory clues for type A aortic dissection to avoid misdiagnosis of acute myocardial infarction. Prompt recognition and pausing intervention can prevent harm and ensure appropriate aortic surgical team activation.
Area of Science:
- Cardiology
- Vascular Surgery
- Diagnostic Imaging
Background:
- Type A aortic dissection can mimic acute myocardial infarction.
- Catheterization laboratory findings may indicate aortic dissection but are often overlooked.
Purpose of the Study:
- To identify and summarize key catheterization laboratory clues for type A aortic dissection.
- To prevent misdiagnosis and unnecessary interventions in patients with suspected myocardial infarction.
Main Methods:
- Retrospective analysis of a case presenting with ST-elevation myocardial infarction.
- Review of coronary angiography and computed tomography angiography findings.
- Identification of recurring angiographic signs suggestive of aortic dissection.
Main Results:
- A 67-year-old man with suspected myocardial infarction showed difficult coronary engagement, left coronary narrowing, and catheter swing during angiography.
- Computed tomography angiography confirmed type A aortic dissection involving the left main ostium.
- Five specific angiographic clues were identified.
Conclusions:
- These 5 catheterization laboratory clues can help differentiate aortic dissection from myocardial infarction.
- Timely recognition and pausing procedures are crucial.
- Activation of the aortic surgical team is essential for appropriate management.

Emergency coronary angiography and computed tomography angiography showing catheterization laboratory (Cath-Lab) clues to type A aortic dissection presenting as acute myocardial infarction.
Case Summary:
A 67-year-old man underwent emergency angiography for anterior ST-segment elevation. Difficult coronary engagement, thin strip-like left coronary narrowing, and marked catheter swing prompted reassessment. Computed tomography angiography confirmed type A aortic dissection involving the left main ostium, and unnecessary percutaneous coronary intervention was avoided. Five recurring angiographic warning clues are summarized.
Take-Home Messages:
These 5 practical Cath-Lab clues would help you away from emergency type A aortic dissection trap. Timely recognition of Cath-Lab clues and pause; activate the aortic surgical team.
