A fifty seven years old female patient came to operating room for coronary artery bypass grafting (CABG) surgery. After induction, invasive monitoring lines were placed. Pulmonary artery catheter (PAC) floated after three attempts and it was wedged at 60cm. ⋯ Knotting usually occurs due to excessive advancement of the pulmonary artery catheter beyond the normally expected distance. The removal of a catheter should never be forced when resistance is encountered. PA catheter knotting is a rare complication but it should be suspected whenever there is excessive length of catheter required to reach pulmonary artery.
