Malposition of the pacemaker lead in the left ventricle

Malposition of the pacemaker lead in the left ventricle.

Eight years of left ventricle pacing due to inadvertent malposition of a transvenous pacemaker lead in the left ventricle.

The inadvertent malposition of a pacemaker lead in the left ventricle is a rare and underdiagnosed pacemaker complication. A 78-year-old woman was admitted to our Emergency Department for progressive dyspnea, 8 years after transvenous pacemaker implantation. Routine 12-lead electrocardiography revealed a right bundle branch block on the paced beats, and lateral chest X-ray showed posterior defl...

Malposition of pacing lead into the left ventricle: a rare complication of pacemaker insertion.

To cite: Bashir A, Noroozian N, Bradlow W, et al. BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2013202131 DESCRIPTION A 79-year-old woman presented with infection and erosion of a permanent pacemaker, which had been inserted 15 years earlier. A chest X-rays showed an abnormal position of ventricular lead, suggesting it was in the left rather than right ventricl...

Pacemaker lead malposition in the left atrial roof is masked by normal pacing thresholds

Pacemaker lead malpositioning with subsequent cardiac tamponade is a rare, but serious adverse event. We herein report a case of pacemaker lead malpositioning in a 76-year old female caucasian patient. The lead was malpositioned into the roof of the left atrium after perforation of the superior vena cava, resulting in cardiac tamponade. After fast surgical revision and an uneventful post-operat...

Pacemaker electrode misplaced in the left ventricle.

This study reports the case of an anomalous implantation of VVI pacemaker electrode in the left ventricle (LV) diagnosed during routine evaluation, two years after implantation. The patient is a 65-year-old woman with Chagas disease. Electrocardiogram (ECG) revealed a pattern of right branch block. Profile chest X-ray showed electrode with posterior curvature path. In transthoracic echocardiogr...
