LBBAP lead parameters were stable pre\u2010\/post\u2010cMRI and out to 9 months. Comparing pre\u2010 versus post\u2010implant cMRIs (median 579 days apart), 1\/9 patients following LBBAP showed a new scar on the RV inferoseptal side directly adjacent to the pacing lead on post\u2010implant cMRI, suggestive of potential implant\u2010related scarring with LBBAP.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>CMRI appears safe for patients with LBBAP pacemakers, with stable short\u2010 and long\u2010term device parameters. In patients with matched pre\/post\u2010implant cMRIs, the new septal scar can be identified with LBBAP implantation, raising the possibility of lead\u2010related fibrosis. Larger studies are required to substantiate whether the single case of lead\u2010related fibrosis is an exception or occurs more frequently.<\/jats:p>\n
