Although many physicians implant cardiac implantable electronic devices, only a small fraction performs transvenous lead extraction (TLE). This has led to inconsistent and, at times, inappropriate patient management. Despite clear Class I recommendations for lead extraction for infected devices,1 patients all too often receive multiple debridements and rounds of antibiotics for device-related infection. In addition, in cases of device system upgrade and lead malfunction, lead after lead is often added, sometimes involving tunneling and frequently resulting in the elimination of vascular access. Why are more of these patients not offered or referred for lead extraction? In many cases, we believe the reason is unfounded fear of the procedure and a knowledge gap. In a survey performed by Spectranetics (Colorado Springs, CO), cardiologists perceived the major complication rate associated with the extraction procedure itself to be >5% and the mortality rate to be nearly 1.5%. Henrikson and colleagues2 performed a similar survey among 252 electrophysiologists (63% of whom identified themselves as performing TLE) with similar observations. More than 75% of respondents perceived the morbidity risk associated with TLE to be ≥2%, and close to 30% of respondents estimated the risk to be ≥5%. Among the group surveyed, the mortality risk with TLE was similarly perceived to be excessive despite the surprising preponderance of “extractionists” among the group. It is not surprising that more patients are not referred if this is the impression. In a global survey of 820 clinicians addressing the understanding of cardiac implantable electronic device infection and lead management, ≤50% of all respondents failed to correctly identify and implement Class I recommendations for device-related infection despite >60% of respondents identifying themselves as performing TLE.3 Clearly, data and education are needed, both of which are lacking.
