Laser lead extraction in congenital heart disease: a case-controlled study.

Journal Article

INTRODUCTION: Patients with congenital heart disease (CHD) and implanted cardiac rhythm management devices have a high rate of endocardial lead issues requiring lead extraction. Laser lead extraction (LLE) is a promising modality for lead management though few studies have evaluated this technique in CHD. METHODS: This is a retrospective, case-controlled (gender- and age-matched, without CHD) analysis of all CHD patients from 2002-2010 at a single institution who underwent LLE as a primary extraction modality. The aim is to evaluate the utility of LLE in patients with CHD compared with controls without CHD. The primary outcome is LLE clinical success. Secondary outcomes include procedural success, complications, and factors related to LLE failure. RESULTS: Twenty-two patients with CHD underwent 24 LLE procedures to extract 35 leads. These were compared with 22 patients without CHD who underwent 24 LLE procedures to extract 37 leads. LLE clinical success was achieved for 26 of 35 leads (74%) in patients with CHD versus 35 of 37 leads (92%) in patients without CHD [P = 0.02]. No factors within the CHD group predicted LLE failure. Six of the nine leads for which LLE was unsuccessful were extracted using other methods. No complications were observed in the CHD group. CONCLUSIONS: Patients with CHD are less likely to have successful LLE than gender- and age-matched controls without CHD. LLE failures in CHD may be related to calcified adhesions. Mechanical-rotational devices and the femoral snare technique are useful for LLE failures. LLE provides an effective first-line approach for patients with CHD.
