Malpositioning of a pacemaker lead to the left ventricle accompanied by posterior mitral leaflet injury

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...

Echocardiographic analysis of posterior mitral leaflet movement in mitral stenosis.

Echocardiographic analysis of the movement of the posterior mitral valve leaflet in 60 patients with lone mitral stenosis, 35 patients with aortic stenosis, and 18 patients with aortic and mitral stenosis showed a spectrum of initial posterior mitral valve leaflet movement in early diastole. The classical anterior movement was seen in 36 out of 60 patients with mitral stenosis (60%), and 8 out ...
