Uncomplicated heart and lung perforation by a displaced ventricular pacemaker lead: a case report.

Lead perforation is a rare complication of pacemaker implantation and associated with the risk of disastrous results like cardiac tamponade or pneumo-hemothorax. We report a patient in whom a ventricular lead perforated the right ventricle and left lung parenchyma without the development of cardiac tamponade, pneumothorax, or hemothorax. No objective evidence for perforation was found on echocardiographic evaluation and thorax computed tomography has made the definite diagnosis. In the literature available to us, it is the first reported case of an uncomplicated right ventricular and lung parenchymal perforation associated with pacemaker implantation.
