Successful retrieval of a knotted pulmonary artery catheter trapped in the right ventricle using a dormier basket.

We report the case of a 71 year old patient in whom a pulmonary artery catheter (Swan Ganz) formed a knot which was fixed within the right ventricle in the region of the tricuspid valve annulus. The catheter was successfully dislodged to the right atrium, subsequently snared by a dormier basket advanced from the right femoral vein and retrieved by localised cut down of the femoral vein.
