One of the pre-surgery questions I asked my surgeon was whether he would have to change tactics and do the full chest opening procedure if there were complications or if the valve needed to be replaced instead of repaired. His answer was that for surgeons comfortable with doing port access (having done A LOT of them!) there was no difference in access and anything that could by done through the full chest procedure could be done through port access.
Sparklette:
My husband had the same surgeon as Katie D and her sister, MaryC, and he told us the same thing.
My surgeon said that the port access incision used to be standard, then surgeons went to a sternotomy. That surgeon prefers a sternotomy, but said if John chosen him to do the surgery, he'd do whatever incision he wanted.
John opted for Dr. Ryan, who has quite a lot of experience with the port access incision.
In fact, Dr. Ryan said if I ever required another MVR, he could do it via port access.
FYI: We were told that overweight people & very well-endowed women are not good candidates for a port access incision.
I can barely see John's incision now, and it's almost 16 months post-op.
