Successful transvenous lead extraction using the Evolution System in a 17-kg child

Abstract

Despite technological advancements in the field of pacemaker lead extraction, available data on pediatric patients is limited, and risk of failure and severe complications remains high. In this report, we present the case of a male patient who, at five months old, had been transvenously implanted with a single-chamber ventricular pacemaker due to complete atrioventricular block. At 7-year of age, the patient was referred to us with growth-related lead tension, severe tricuspid insufficiency, and weak battery. We extracted the lead using the Evolution System and replaced the unit with a dual-chamber pacemaker with a SelectSecure lead. This new system can be used for lead extraction even in lowweight pediatric patients with congenital heart disease. Using a thin, lumenless SelectSecure lead appears to reduce the risk of venous obstruction.
