A Doctor's Revenge

When I did him wrong, I knew that he'd try to get revenge in the future.
He was a doctor who operated on me and he used the wrong suture.
When I met my wife, he and she were involved.
During my heart valve operation, he deliberately used a suture that would dissolve.
He used dye to make it look like the kind of suture that is permanent.
Another doctor discovered his crime and prison is where he went.
Two years ago another doctor fixed my heart with another operation.
I'm happy because my death would've caused my family devastation.
