Malposition of a transvenous cardiac electrode associated with amaurosis fugax

Pacing Clin Electrophysiol. 1983 Jan;6(1 Pt 1):119-24. doi: 10.1111/j.1540-8159.1983.tb06589.x.


A 55-year-old male received a transvenous ventricular pacemaker for sick sinus syndrome. After pacemaker insertion, he developed recurrent episodes of amaurosis fugax. The source of thromboemboli was the pacemaker electrode malpositioned in the left ventricle. Position of the electrode was diagnosed correctly by two-dimensional echocardiography. The malpositioned electrode was successfully removed with cessation of recurrent thromboembolic phenomenon.
