Explanting infected cardiac implantable electronic devices (CIEDs) and extracting their associated leads can be performed percutaneously (EP) or via open-thoracotomy (OR) approach. In this study, we examined the characteristics and outcomes of infected CIED patients undergoing EP vs. OR extraction procedures.All patients (EP: n = 329 and OR: n = 24) who received lead extraction in the presence of an infected CIED from 2005 to 2010 at the University of Pittsburgh Medical Center were included in this study. Demographic and clinical characteristics were obtained from the electronic medical records. The Charlson comorbidity index (CCI) was used to adjust for severity of co-morbid conditions.Compared to the EP group, OR patients were more likely to have positive blood cultures, larger vegetations, and worse CCI scores. They also had higher total mortality rates at 1 (p = 0.036), 6 (p = 0.020), and 12 months (p = 0.012) after the procedure. One-year survival after lead extractions was significantly better for the EP compared to the OR group (p = 0.002) even after adjusting for other comorbid illnesses (HR = 2.6, p = 0.010) in a Cox regression model.Infected CIED patients undergoing open-chest lead extraction are sicker and have higher mortality rates compared to those undergoing percutaneous extraction. Randomized, prospective data are needed to determine whether the procedural strategy for lead extraction accounts in part for the difference in outcome.
