Key result

Lead extraction and repositioning safely corrects inadvertent LV pacemaker placement via PFO.

Why the study?

Misplacement of a pacemaker lead into the left ventricle is a rare but clinically important complication often facilitated by unrecognized intracardiac shunts, where early recognition is essential to avoid systemic embolization.

Population

One man in his 70s with inadvertent left ventricular pacemaker lead placement across a PFO

Implication

Alerts clinicians to PFO-related LV lead misplacement; leaves open optimal surveillance strategies.

Key Points

To discuss a case of pacemaker lead misplacement into the left ventricle due to a patent foramen ovale.
Case report of a patient with a history of cardiac surgery requiring pacemaker implantation.
Echocardiography used for surveillance, revealing lead misplacement into the left ventricle.
ECG assessed for paced morphology indicative of left ventricular pacing.
Lead repositioning confirmed using fluoroscopic imaging and post-procedural checks.
Initial lead placement went unnoticed due to a patent foramen ovale.
Patient remained asymptomatic, with no systemic embolization detected.
Successful lead extraction and proper repositioning into the right ventricle.
Multiple imaging techniques confirmed correct lead placement.

Structured PICO

Population

A man in his 70s who underwent permanent pacemaker implantation and was found 1 year later to have the ventricular lead misplaced in the left ventricle via a patent foramen ovale.

Intervention

Anticoagulation with apixaban followed by pacemaker lead extraction and repositioning into the right ventricle.

Outcome

Successful lead extraction and repositioning into the right ventricle.

Inadvertent left ventricular pacemaker lead placement via a patent foramen ovale can be detected by an RBBB-like paced morphology and managed safely with anticoagulation and lead repositioning.

Cite This Study

Helal et al. (2026) conducted a case report in Misplacement of pacemaker lead into the left ventricle (n=1). Lead extraction and repositioning was evaluated. A man in his 70s with inadvertent left ventricular pacemaker lead placement via a patent foramen ovale was successfully managed with anticoagulation, lead extraction, and repositioning.
