Lead failure due to the subclavian crush syndrome in a patient implanted with both standard and thin bipolar spiral wound leads.

Subclavian crush syndrome is a well-described cause of pacemaker lead failure resulting from an entrapment of a lead or leads between the clavicle and the first rib. A new thinner lead (ThinLine) was designed to minimize this complication. Our patient developed atrial and ventricular lead subclavian crush syndrome with both conventional and thin leads.
