Hi Judye,
Being diagnosed with an ascending aorta dilation is a scary diagnosis, earlier this year I was diagnosed with the same (4.5). Since then I have been monitored and had various tests.
Try to keep calm, it is essential to keep blood pressure as low as possible to relieve stress on the dilation. Your cardiologist will suggest BP reducing medicine to help.
A dilation of 4.2 is considered low risk, much lower than risks of surgery that's why your cardiologist is not suggesting surgery at this time.
Usually surgery isn't recommended until 5.0, so it maybe many years before that becomes necessary, do all the things you like doing and ever wanted to do and enjoy each day.
Take care
Darren.
