At the moment I'm waiting to have an ICD fitted due to severe heart failure. Yesterday I was told that I need two new kneecaps but they are reluctant to perform the op but will see how I am after my ICD. The main problem being the anaesthetic. They said that they can do it with an Epidural but that sounds a bit scary to say the least. My question is. Has anyone here had such an operation with the Epidural and if so how was it for you ?
