@komara I have to admit I am beyond surprised a cardiologist would refer to your aneurysm as "small", you should be closely monitored, your aneurysm is on the larger side. Mine was 5.2 cm when my surgeon recommended it should be repaired. I understand you have other comorbidities that could make your surgery risky, but all of those factors would be evaluated by a qualified surgeon, he/she would help you make the best decision based on all the risks. Please find a surgeon (and I would say a new cardiologist too) ASAP. All the best to you!!!
