case_images: During right heart catheterization, the 6F pigtail catheter (arrow) was entrapped in the chordate tendineae of the septal leaflet of the tricuspid valve (A). The introducing sheath was removed after the hub of the pigtail catheter was cut (B). A biopsy sheath was introduced over the catheter (C). The sheath was peeled off until the cut end of the pigtail appeared (D).

case_images: First, the sheath introducer was removed (Figure 1A). Then, the hub of the pigtail catheter was cut (Figure 1B) and a 7 F; 90 cm biopsy sheath (Cordis Corporation, Miami, FL, USA) which had the hemostatic valve cut off was advanced over the pigtail catheter with the support of the exchange guide wire (Figure 1C). So we started shortening the sheath by cutting it gradually, until the end of the pigtail appeared (Figure 1D).
