Acute Aortic Syndrome
| Purpose | Acute aortic syndromes (AAS), including acute aortic dissection are life-threatening emergencies affecting about 10,000 cases per year in the United States. |

Value Proposition
Acute aortic dissection has high early mortality with a death rate as high as 1% per hour during the first 24 hours. Automatic detection improves time-to-intervention and thereby improves mortality.
Narrative(s)
A patient arriving to ED with pleuric chest pain. Differential diagnosis is wide. The patient receives chest CT. Automation allows parallel triggering of the AAS management, and prioritization on the radiologist worklist for immediate review.
Workflow Description
The image is obtained from modality and sent to PACS and the AI engine. The image is analyzed by the engine. The system then detects probability of acute aortic syndrome. An alert message is sent to PACS from the engine with the information, identification, and graphic highlighting the features of the image that are most influential to the model prediction.
Considerations for Dataset Development
| Aortic Dissection | {acute, subacute, chronic} |
| Ischemia | {abdominal organ ischemia, limb ischemia, ischemic or embolic stroke, paraplegia} |
| Comorbidities | {hypertension, inherited connective tissue disorder, atherosclerosis, vasculitis, coronary artery disease, chronic obstructive pulmonary disease} |
| Aortic emergencies | {Aortic dissection, aortic intramural hematoma, penetrating atherosclerotic ulcer, aortic aneurysmal rupture, traumatic thoracic aortic injury, traumatic abdominal aortic injury} |
| Smoking history | {Yes, No} |
| Aortic aneurysmal rupture | {Intraperitoneal rupture, retroperitoneal rupture, aortocaval fistula, primary aorto-enteric fistula} |
