Defibrillator lead dislocation after manual lumbar traction

We report a 63-year-old patient with prior coronary artery bypass surgery and recent history of recurrent hospital admissions for refractory heart failure because of ischemic cardiomyopathy and sustained ventricular tachycardia. The patient underwent ICD implantation through left subclavian vein approach (Medtronic, single chamber, model-Maximo II VR, D284VRC, with 6947 ventricular active fixation lead). This case report describes the first patient, to our knowledge, with defibrillator lead dislocation after manual lumbar traction for low back pain. The patient was admitted to the emergency service with severe chest pain, and electrocardiography revealed 0.5–1 mm ST-segment elevation in leads DII, DIII, and aVF. After initial evaluation, coronary angiography and percutaneous coronary intervention were immediately performed with the diagnosis of acute inferior myocardial infarction
