Heart Cath

The above image was taken during my fifth heart cath on Thursday. Normally the procedure lasts 30-45 minutes. This one was a three and half hour marathon. Since you are semi-conscious during the procedure, I wasn't sure I was going to make it; but obviously, since I am posting this, I did.
I am always intrigue by the images and xrays that show the wires holding my sternum together. These are the dark twisty loops in the image. They very much remind me of "bailing wire". Before duct tape and super glue, bailing wire was the fix all tool. I remember seeing twisted wire loops like the ones in my chest on all types of repairs that my grandad made from broken hoe handles to pipe stems.
