I do have a cardiologist in Omaha, Nebraska. I do have a pulmonary embolism and have a filter (I think it is a Greenfield filter?) also take plavix and a aspirin every day. I live in southwest Iowa. I have been seeing the same cardiologist for over 20 years and he has never suggested that I should get a 2nd opinion; in fact I sometimes wonder why he doesn't. He keeps telling me that he doesn't think we would be able to find a surgeon willing to do it
