Having a big heart is one thing. Having big atria are another. The two atria are the small chambers of the heart, one of which contains the sinus node, responsible for the origination of the heart beat. When the atrium enlarges, the patients faces a higher risk of sustaining an unfixable atrial fibrillation.
So it doesn't surprise me that my patient in atrial fibrillation had atrial enlargement of 8.1 cm on cardiac echo. That's huge and it is probably the largest atria I'll ever see. For a cardiologist, this is probably a Holy cow moment. I'm not sure what the urologist equivalent is. That would be an interesting conversation , none the less.
