Earlier today Barbara Walters announced that she is having a heart valve replaced later this week.
Interestingly she has had Saturn going over her Sun (1 degree Libra) and Ascendant (4 degrees Libra)-as of November of 2009. Also Saturn squared her Moon last fall and Pluto squares her Sun and Asc this year.
In 2011 her progressed Sun will be conjunct her natal Saturn, and her progressed Saturn squares her Sun.
I imagine this will be a very trying time period for her.
