Laser lead extraction combined with baffle stenting is a feasible approach to facilitate dual chamber ICD upgrade and improve exercise capacity in patients with complex congenital heart disease.
Supports feasibility of combined extraction-stenting for ICD upgrade in complex CHD; leaves open confirmation of exercise benefits in prospective studies.
A case of successful laser extraction of a defibrillator lead with baffle stenting in a 15-year-old boy with dextrocardia, L-transposition, ventricular septal defect, and pulmonic stenosis status-post Senning/Rastelli repair is presented. Six-month follow-up revealed a significant increase in exercise tolerance and maximum oxygen consumption (VO(2)max).
