Two-dimensional echocardiograms of a transvenous left ventricular pacing catheter.
A permanent transvenous pacemaker lead was placed across the atrial septum and retained in the left ventricle for eight years. M-mode echocardiograms showed a linear echocardiographic density in the left atrium and mitral valve. Cross-sectional echocardiograms further defined the location and course of the pacing lead.
