Is Transesophageal Echocardiogram Advisable When Suffering From High BP?

I am 83 yr. old female. Recently had echo cardiagram - and tech who performed procedure, noted everything looked fine. A few days later, my physician called and said the cardiologist found a questionable area which could be an aneurism, and that cardiologist wants to perform a transesophageal echo cardiagram. I do have high blood pressure - for which I am taking medicine. But, I do not have any dizziness, shortness of breath, of chest pain or discomfort. Reluctant to undergo TEE. Should I? Dot
