I had my aortic valve and root replaced 1 year ago (July 12, 2010). This was my 2nd AVR in a year (had my Aortic root replaced on July 8, 2009). It had to be re-done due to a previously unknown defect in my root that they detected in my 1st surgery. I have no idea about the arteries having to be re-attached, I didn't ask about this.
