Implantation of pacemakers in cardiac dextroposition is complicated but not insurmountable. Introduction Cardiac dextroposition, as opposed to dextrocardia, is an acquired horizontal displacement of heart to the right hemithorax with normal alignment of the major axis of the heart, caused by disease processes that either pull or push the heart to the right. Although dextrocardia can pose technical challenges when interventional treatments are required in such cases, dextroposition can be even more challenging given the distortion of normal anatomical relationships and the uncertainty of the accurate location and borders of the cardiac structures caused by the shift and rotation effected by the pathologic process. We present a complicated but successful case of implantation of a leadless pacemaker (Medtronic Micra; Medtronic Inc, Minneapolis, MN) in a patient with cardiac dextroposition that was incidentally found at implant.
