CTICasesRetained Cardiac Sheath post-Lead Revision
Imaging findings
Lateral chest radiograph and CT show a linear, rigid plastic foreign body traversing the myocardium of the right ventricular apex into the pericardial fat, representing a sheared-off portion of a catheter sheath from a CRTD lead revision.
Key takeaways
During complex cardiac device lead revisions, sheaths can break or shear off. These fragments can migrate or perforate the myocardium, presenting as linear foreign bodies on post-procedure radiographs and necessitating surgical extraction.
