You should discuss the matter with your cardiologist - it seems unlikely that you would develop an infection after a year but your physicain is the expert and can advise you as to any potential problems.
You have a two year statute of limitations in Colorado for filing a medical malpractice claim, you must file within two years of the act of negligence or lose your right to do so.
