A 70-year-old man underwent cardiac surgery including left atrial appendage closure. A pigtail catheter was inserted into the pericardial sac because of delayed tamponade. Removal of the catheter was planned for 2 days after drain insertion. However, the resistance was high and pulsatile. The patient was transferred to the catheterization laboratory and a guide wire was inserted through the catheter, revealing the catheter route around the left atrial appendage. The wire was exchanged for a stiff wire to uncurl the catheter as much as possible, then the catheter was removed. The left atrial appendage does not usually represent an obstacle to catheter removal because it is soft and shrinkable. However, once the left atrial appendage becomes closed off, it can become hard, unshrinkable and an obstacle that might be caught by the drainage catheter.
