... My wife just underwent robotic mitral valve repair surgery. Dr. Douglas Murphy at St Joseph's Hospital performed the surgery and it was very successful. People come from all over the world to have their mitral valves repaired by this gentleman. He has performed over 1300 mitral valve repairs and last year alone performed 200 of them. We would recommend him to anyone who needs mitral valve surgery. It is the least invasive procedure for mitral valve repair.
