Yesterday, I had a shoulder arthrogram and MRI. I had a form to fill out and all these questions to answer about previous surgeries, implants, pacemakers, heart valves, wire sutures, and the like. I truthfully answered each one. I checked YES for mechanical heart valve and YES for wires in my chest (I had a rib removed and wired back into place during VR). I had my MRI compatible card ready to show them and I had already in my mind determined that the wires wouldn't present a problem either. They didn't. I was surprised that no one asked about either affirmative answer though. After the MRI, I asked the tech and she said, "most heart valves are OK these days." It just seemed a bit sloppy and reinforced my belief that we all have to be alert and informed regarding our own health issues.
