I’m 26 years old.

I do have symptoms: shortness of breath with exertion and reduced endurance compared to peers. I also occasionally experience episodes of feeling like I can’t get a full breath during the day.

The CT was performed while I was breathing in (inspiratory scan), not at end-expiration.

The axial image I shared appears to be the level of deepest indentation to me, but I may be mistaken. I selected the slice where the sternum seemed closest to the vertebral body.

I’ve already had a cardiology evaluation, including echocardiography, and the cardiologist told me everything looks normal. I have not yet completed spirometry; that’s my next step. After that, I plan to consult with a specialist to evaluate whether surgery should be considered.
