Retained Lead Fragments and MRI
I have a question on whether having a retained lead fragment from a prior lead extraction is a contraindication for MRI scans. I had to get my left ventricular lead replaced two years ago but during the extraction process the lead broke twice. They were able to get most of the lead out, but ending up abandoning a ca. 5 mm long ring electrode on the wall of the vein going to my heart. This electrode is made out of a Platinum/Iridium alloy. They succesfully got another left lead installed. Yea.
I sustained a right knee injury last fall. My orthopedic doc. thinks I tore my ACL, and has ordered an MRI for this. My pacing system is "mixed" leads from two manufacturers so it is not MRI conditional. I have to schedule the MRI at a specialist center as a result. The assistant I spoke to there said that retained lead fragments are generally exclusion criteria for an MRI, but that they'd look at the chest x-ray before making a final determination.
Have any of you been in this situation and what was the outcome? Were you able to get the MRI even with some extra shrapnel in there?
