New and a little scared

Hello everyone. I am new here. My husband last week had a dissecting aortic aneurysm and had to have emergency open heart surgery to have his aorta replaced and a new valve put in. He is only 33 years old. They believe a heart condition he has had since birth was the cause. He is still in the hospital but due to come back anyday now. I would love some tips or if you can just let me know what we might expect when we make the transition home. Thanks, Candace
