E. Mucha et al., FRACTURE AND MIGRATION OF A PACEMAKER ATRIAL LEAD RETENTION WIRE FOUND BY FLUOROSCOPIC SCREENING IN AN ASYMPTOMATIC PATIENT, Southern medical journal, 89(8), 1996, pp. 798-800
We present the case of a woman who had an Accufix atrial ''J'' pacemak
er lead implanted in 1990. Subsequently, Telectronics Pacing Systems r
ecalled two models of the atrial leads after problems with fracture an
d malfunction were reported. One of these models was used in our case.
Fifty-two months after implantation, following recommended fluoroscop
ic screening, our patient was found to have a complete fracture of the
''J'' retention wire with one fragment protruding from the sheath in
the right atrium and another fragment of the wire lodged in the right
ventricle. The pacemaker had continued to function normally and there
was no clinical evidence to suggest such a potentially disastrous frac
ture. Our report emphasizes the importance of fluoroscopic screening o
f all patients with atrial leads involved in the recall.
