Superior vena cava (SVC) injury is a rare but dreaded complication during percutaneous transvenous lead extraction (TLE) that carries high morbidity and mortality. Despite technological advances and improved efficacy, complication rates remain unchanged. ⋯ In patients presenting for TLE, simultaneous traction results in increased separation and a more parallel alignment of the lead and SVC wall, allowing the sheath to be better oriented in the desired cleavage plane. This improved sheath alignment is particularly critical when powered sheaths are to be used.
