Sep 4, 2025
In this engaging discussion, Dr. Christopher Francois, a diagnostic radiologist at the Mayo Clinic, shares insights on the rising risks of thoracic aortic dissection associated with aortic dilation. He highlights the critical need for accurate assessments and explains when traditional imaging falls short. Dr. Francois dives into innovative techniques like MR and CT angiography, emphasizing AI's role in enhancing efficiency. Listeners will learn about risk factors for aneurysms and the value of a multidisciplinary approach in patient care.

Episode notes
Who Is At Higher Risk
- Most thoracic aortic aneurysms are sporadic and occur in patients over 60, especially with hypertension.
- Family history, connective tissue syndromes, and bicuspid aortic valve raise risk at younger ages.
Act On Abnormal Chest X‑Ray Clues
- Treat chest x-ray findings like accentuated aortic contour as a clue to get follow-up imaging.
- Recognize age-related tortuosity can mimic dilation but still warrants further assessment if noted.
Start With Transthoracic Echo
- Start aortic evaluation with transthoracic echocardiography for thoracic or abdominal aorta concerns.
- Use echo because it is portable, inexpensive, radiation-free, and measures aortic size and valve function well.
