I was truly touched by this story and it brought tears to my eyes. To have a second chance at life is something so many do not get. I am a spiritual person but not through the views of Christianity, and I do not believe in miracles..or do I? Miracles are nothing short of Magick, for through magick (I use a K to differentiate between stage Magic) as we Wiccas practice, it is also a sending out of prayers and lighting candles for those in need to aid in healing, to aid in spiritual comfort, similar to those who light candles in a church, or kneel down and pray to their God. So, there are minute differences.  
I also believe there are no coincidences in life. That things do happen for a reason, even death. But, for this couple, as you have said Dr. Phil, "...kissing through and oxygen tube..." now that's love... 
I pray for their lifelong happiness for who could better understand each other than those who have gone through the same fears, anxieties, and life regenerating experience. 
I missed the show, but I do try to read about them when I have the opportunity...I am glad I came here this morning. 
Brightest Blessings
