Welcome to Connect, @jeanern01,

I moved your message and combined it with this existing discussion on Kommerell’s Diverticulum so that you can connect with others. Simply click VIEW & REPLY in your email notification to find your post.

Kommerell’s diverticulum is a rare congenital disorder. It may be asymptomatic and can be detected as an incidental finding (as in your case), or it can present with symptoms related to chest compression. Aortic diverticulum consists of an aneurysm of the thoracic aorta as well as an aneurysmal opening of an aberrant subclavian artery. Here is a Mayo Clinic video that might interest you:

According to the latest findings, published in the Journal of the American College of Cardiology, “Symptomatic patients with this anomaly may benefit from surgical correction, while we can take a “wait and see” approach in the asymptomatic.” http://www.onlinejacc.org/content/73/9_Supplement_1/2776

You are quite correct, that there appears to be little research on this condition, but I found a few articles/studies which I hope you might find helpful:

I’m so glad to hear that you are entrusting your care with Mayo Clinic. Now that you’ve been diagnosed @jeanern01, has your doctor outlined any next steps?
