Migration of intracardiac transvenous pacing leads may occur. There is a known risk of intrapul‐ monary ventricular pacing lead migration in patients with endocardial lead systems. In the current report we present the late intrapulmonary migration of an endocardial atrial pacing lead body. The patient had undergone antitachycardia pacemaker placement to control recurrent atrial tachyarrhythmias following the Fontan procedure. Although the lead electrode remained in place and continued to pace, the lead body migrated, causing severe obstruction to blood flow. This resulted in severe cardiac decompensation, which was ultimately ameliorated by lead repositioning.
