While pacemaker endocarditis is rare, it is a complication that mandates removal of the permanent pacemaker system, including the electrode lead. Many modes of lead removal have been used. The choice of method is determined largely by lead type and chronicity (i.e., risk of substantial adhesions, hence, lead tip mobility). ⋯ Transesophageal echocardiography appears to be particularly sensitive. If vegetation is detected, open heart surgery should be strongly considered for lead removal as opposed to dilator sheath counter traction. The latter method risks shearing off the vegetation, which may result in septic--even massive--pulmonary embolus.
