FIG1
Upon admission, the patient was asymptomatic, but chest radiography showed that the disconnected catheter had its proximal end located in the superior vena cava and its distal end in the right ventricle (Figure 1).

FIG2
A triple-looped snare catheter was advanced through the sheath to the lodged site, and the snare was used to capture the tip of the catheter fragment and was then carefully withdrawn through the right femoral vein and externalized (Figure 2).
