I have Persistant AF which luckily causes me little inconvenience and no symptoms. At a routine scan it was noted i had a dilated Aorta root of 5cm. It was advised and offered for me to have the root repaired/ replaced. I am due for surgery at the Liverpool Heart and Chest hospital on the 4th May...i am very anxious of the recovery....of the outcome...everything. I am seriously thinking of backing out. My mind is running riot, can't sleep, everynight waking at 2am. I am a 70 year old man, relatively fit...and feeling vulnerable and very scared if what the future holds for me right now.
