Hi June
Im sorry to hear you are having some heart valve problems. It sounds like it might be a transesophageal echocardiogram which can be done to check the heart valves and see how well they are working. This is done by passing a probe down the esophagus but you would be given a sedative to make this comfortable.

I havent had this done myself but I guess it is something similar to the process of getting an upper endoscopy (scope down the throat) and I had that done before. I dont remember anything about it because the sedative just knocked me out.
Make sure you ask the nurse all the questions you need answered. Get her to explain the test and how it will be administered, etc.
Someone else might have some experience of the test and be along soon.
Luv n stuff
