Surgical repair safely corrects an inadvertently placed LV pacemaker lead through an undiagnosed PFO.
Case Report (n=1)
No
Left ventricular malposition of a pacemaker lead through an undiagnosed patent foramen ovale is a rare complication that should be suspected in patients with new symptoms or right bundle branch block after recent lead placement.
May warrant TEE vigilance for new murmurs post-pacemaker; leaves open true incidence of PFO lead malposition.
A 53-year-old male status post pacemaker placement three months prior for sinus bradycardia presented with worsening dyspnea, holosystolic murmur, and a ventricular-paced right bundle branch block on electrocardiogram. Transesophageal echocardiography demonstrated a pacer wire in the right atrium coursing into the left atrium and ventricle through an undiagnosed patent foramen ovale. The patient underwent surgical repair and repositioning of the pacemaker lead without complication. Although rare, it should be suspected after recent lead placement.

Suraci et al. (2020) conducted a case report in Inadvertent left ventricular pacemaker lead placement (n=1). Surgical repair and repositioning of pacemaker lead was evaluated on Clinical outcome after surgery. A 53-year-old male with an inadvertently placed left ventricular pacemaker wire through an undiagnosed patent foramen ovale underwent successful surgical repair and lead repositioning without complication.
