Why the study?
What is the prevalence of asymptomatic pacemaker and ICD lead perforation on CT, and does it correlate with electrophysiologic data?
What is the prevalence of asymptomatic pacemaker and ICD lead perforation on CT, and does it correlate with electrophysiologic data?
Asymptomatic lead perforation is common (15%) on CT imaging, particularly for atrial and ICD leads, but rarely results in electrophysiologic consequences.
No takes yet. Share an insight, caveat, or question.
Alerts clinicians to frequent asymptomatic CT perforations without EP changes; leaves open whether imaging alters device management.
Hirschl et al. (2007) studied this question.
