I AGREE WITH HOUSTON 10,000%.

A 5.8 cm thoracic aortic aneurysm is large enough that it should not go unmonitored for a year. That size is close to or beyond the usual surgical threshold depending on where in the thoracic aorta it is located and your body size, age, and overall condition. Generally, once an aneurysm reaches around 5.5 cm in the ascending aorta or 6.0 cm in the descending aorta, surgery is typically recommended or at least seriously considered.

You should not wait a year for your next appointment. You need updated imaging—CT angiogram or MRI—so your cardiologist or a cardiac surgeon can determine the growth rate and decide whether it’s time for intervention. Rapid growth or symptoms like chest pain, shortness of breath, or a new hoarse voice require urgent attention.

I had an acute Type A dissection in 2015 that nearly took my life. It taught me that ignoring these things, even for a few months, can be catastrophic. Get a second opinion, preferably from a thoracic or cardiovascular surgeon who specializes in aortic disease. You deserve clarity, monitoring, and a plan—not silence. Peace.
