a Chest radiography [postero-anterior (PA) view] the day after pacemaker implantation. b Lateral view. c Chest radiography (PA view) upon presentation to the emergency room showing an altered position of the RV lead (arrowhead). d Lateral view (arrowhead shows altered lead position). e Transthoracic echocardiography (subcostal view) suggesting myocardial perforation of the RV lead through the RV apex (arrowhead), but without pericardial effusion, raising doubt as to whether the lead tip lay in the pericardial space.
