Extraction of the inner coil of a pacemaker lead slid into the pulmonary artery.

A patient required lead extraction for chronic draining sinus, due to abandoned leads. Preoperatively, the chest film showed a filament in the right pulmonary artery: it was the inner coil of an old atrial lead that, while remaining anchored to the auricle, slid outside the outer coil. By right subclavian approach, the old ventricular lead and the outer coil of the atrial lead were removed. Then, by right jugular approach, the freely floating end of the inner atrial coil was grasped by a pig-tail catheter, drawn back into the superior vena cava, exteriorized by a Lasso catheter, and finally extracted.
