A patient accidentally received permanent left ventricular pacing via an unexpected atrial septal defect. Echocardiography and imaging confirmed lead malpositioning, with no embolic events during 43-month follow-up.

Area of Science:

  • Cardiology
  • Medical Imaging
  • Electrophysiology

Background:

  • Transvenous permanent pacing is a standard cardiac procedure.
  • Lead placement typically targets the right ventricle or atrium.
  • Unexpected lead malpositioning can lead to significant complications.

Observation:

  • A case report detailing a patient with inadvertent transvenous permanent left ventricular pacing.
  • An unexpected atrial septal defect facilitated the abnormal lead placement.
  • Diagnosis was confirmed using two-dimensional and transesophageal echocardiography.

Findings:

  • Radionuclide phase image analysis revealed an abnormal pattern of electrical activation.
  • The patient was monitored for 43 months on antiplatelet therapy.

  • No systemic embolic phenomena were observed during the follow-up period.

    • Implications:

    • Highlights the importance of recognizing and diagnosing lead malpositioning.
    • Discusses various causes, detection methods, and prognosis of left ventricular pacing.
    • Reiterates a simple method for early detection of lead malpositioning.
