Inadvertent left ventricular pacing through the pericardium

Area of Science:

• Cardiology
• Medical Devices
• Cardiac Electrophysiology

Background:

• Pacemaker implantation is a common procedure for managing cardiac rhythm disorders.
• Inadvertent lead placement is a rare but significant complication.
• Understanding lead migration pathways is crucial for patient safety.

Observation:

• A case of a pacemaker ventricular lead inadvertently placed in the left ventricle (LV) is presented.
• The lead traversed the mediastinum, entering the heart through the posterior left atrial wall.
• Diagnostic imaging, including transesophageal echocardiography and venography, was vital.

Findings:

• The study details the unusual trajectory of a misplaced pacemaker lead.
• Diagnostic imaging successfully elucidated the lead's aberrant path.
• Percutaneous removal of the misplaced lead was achieved without any complications.

Implications:

• This case highlights the importance of vigilant lead placement and intraoperative assessment.
• Advanced imaging techniques can aid in diagnosing and managing lead misplacement.
• Successful percutaneous retrieval minimizes the need for more invasive procedures.
