Asymptomatic Late Migration of an Atrial Pacemaker Lead into the Right Lung

Figure 1

(a) Postimplant anteroposterior chest radiography showing the atrial lead positioned at the basal part of the right atrial appendage. (b) Anteroposterior chest radiography performed at 8 months showing a clear late migration of the atrial lead into the right lung. (c) Contrast-enhanced CT-scanner with maximal intensity projection (MIP) and (d) volume rendered reformatting (anterior view) demonstrating the migration of the atrial lead into the right lung. Notably the pericardium, pleura, and pulmonary parenchyma were normal. RA: right atrium; RV: right ventricle; PA: pulmonary artery.
