    A dislodged pacemaker lead migrated into the right ventricle, causing significant blood clots and pulmonary embolism. This rare complication highlights the need for vigilance in pacemaker patients, even those undergoing repeat surgeries.

    Area of Science:

    • Cardiology
    • Medical Device Complications
    • Cardiac Electrophysiology

    Background:

    • Pacemaker implantation is a common procedure for managing cardiac rhythm disorders.
    • While generally safe, pacemaker systems can be associated with rare but serious complications.
    • Increasing numbers of patients require secondary surgical interventions for pacemaker-related issues.

    Observation:

    • An unusual case of a separated pacemaker probe dislocating into the heart.
    • The dislodged probe was found to have coiled within the right ventricle.
    • This event was associated with the development of extensive parietal thrombosis around the pacemaker cable.

    Findings:

    • The parietal thrombosis led to a massive pulmonary embolism, a life-threatening condition.

  • Diagnostic challenges and secondary complications related to this event were identified.
  • Effective therapeutic and prophylactic strategies were discussed in the context of this case.

    • Implications:

    • This case underscores the critical importance of excluding such severe pacemaker lead complications.
    • Even with advancements in pacemaker technology and surgical techniques, vigilance is paramount.
    • Preventing and managing pacemaker lead dislocation and associated thrombosis is crucial for patient safety.
