Background:
Coronary occlusion during type A aortic dissection is a serious complication, associated with high mortality if not identified and treated promptly.
Case Summary:
We present a case of acute type A aortic dissection, diagnosed with intravascular ultrasound during emergency percutaneous coronary intervention (PCI) for ST-elevation myocardial infarction. Emergency PCI was successfully performed as a bridge to definitive central aortic repair surgery.
Discussion:
This case highlights the integration of multiple diagnostic cardiac imaging modalities in the time-critical evaluation and management of aortic dissection as a cause for ST-elevation myocardial infarction. This case also demonstrates the coordinated multidisciplinary care essential to the initial and long-term management of this life-threatening condition.
Take-Home Messages:
This case highlights the ability to promptly diagnose acute type A aortic dissection using intravascular ultrasound in patients presenting with acute coronary syndrome. Initial reperfusion with PCI can provide a life-saving bridge to definitive surgical repair.

Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for...
