Three patients from different centers with pacemaker or ICD leads endocardially implanted
in the left ventricle are described. All leads, two ventricular pacing leads and one ICD lead …

Implantation of pennanent transvenous cardiac pace-makers is currently in its fourth decade.
l Over 117,000 pacemakers were implanted at 3,400 centers in the United States in 1989. 2 …

Background. The inadvertent lead malposition in the left heart (ILMLH) is an under-
recognized event, which may complicate the implantation of cardiac electronic devices …

It is known that an electrocardiogram (ECG) after transvenous right ventricular (RV) pacing
should yield left bundle branch block (LBBB) QRS patterns. When right bundle branch block …

An inadvertently placed pacing lead in the left ventricle (LV) is a rare and often
underdiagnosed complication of pacemaker implantation. We present a case of a 73-year …

Transmural Pacing in Congenital Heart Disease. Introduction: Some patients with
postoperative congenital heart disease require permanent cardiac pacing, but the use of …

Transvenous pacemaker lead malposition in the left ventricle occurs rarely and requires a
high index of suspicion for proper diagnosis. The case of a woman with unintentional lead …

Inadvertent lead placement in the left ventricle (LV) is an uncommon and often under-
diagnosed complication of cardiac device implantation. Thromboembolic (TE) events are …

Malposition of a cardiac pacemaker lead within the left ventricle represents a source of early
and late thromboembolic complications. We report a case of cerebral embolism, caused by …

Background: Transvenous pacemaker catheters may be placed unintentionally into the left
ventricle. This can lead to thromboembolic complications. Methods and Results: We report …
