Pacemaker lead perforation is a rare complication of pacemaker device implantation. We report a case where a ventricular lead perforated through right ventricle, pericardium and went into left lung parenchyma without the development of pericardial effusion, cardiac tamponade, pleural effusion, pneumo or hemo thorax. Patient presented with complaints solely related to failure of pacing rather than disastrous or life threating complications. Echocardiography didn't reveal any evidence of perforation and it was detected on fluoroscopy and computed tomography helped in making the diagnosis. Patient was treated with second procedure where second device placed on other side without manipulating previous device or lead.
