A 54-year-old woman with non-ischaemic dilated cardiomyopathy and syncopal episodes due to ventricular tachycardia had undergone implantation of a three-chamber implantable cardiovertor-defibrillator (CRT-D, Contak Renewal 4 Guidant, St Paul, MN, USA). A passive fixation bipolar lead was placed in the appendix of the right atrium (Guidant Fineline Sterox II 4480), a passive fixation bipolar, dual-coil lead (Guidant Reliance 0148) was placed in the apex of the right ventricle, and a bipolar left-ventricular (LV) pacemaker lead (Guidant Easytrak 3 4527) was placed in a lateral tributary of the coronary sinus. Forty days after the implantation, the patient presented with occasional muscle twitching on the left side of her chest. Her symptoms were reproduced immediately after the output voltage of the LV lead was increased. Fluoroscopic examination revealed that the LV lead was coiled around the pulse generator and retracted (Figure 1). The right ventricular lead was minimally retracted, whereas the atrial lead was intact. Revision of the CRT-D was also performed.

Twiddler's syndrome is characterized by the coiling of the pacemaker lead due to the rotation of the pacemaker generator on its long axis.1
