Insights
A dislodged pacemaker lead migrated to the left atrium through a patent foramen ovale, causing transient ischemic attacks. Transvenous lead extraction successfully treated the patient, highlighting the need for anticoagulation during lead retraction.
Area of Science:
- Cardiology
- Medical Devices
- Electrophysiology
Background:
- Permanent transvenous DDDR pacemakers are implanted for complete atrioventricular block.
- Lead dislodgement is a known complication of pacemaker implantation.
Observation:
- A 76-year-old woman experienced recurrent transient ischemic attacks four years after pacemaker implantation.
- The cause was identified as dislodgement of the atrial lead into the left atrium via a patent foramen ovale.
Findings:
- Successful transvenous extraction of the dislodged atrial lead was performed.
- The patient remained asymptomatic with an uneventful 12-month follow-up post-procedure.
Implications:
- This case underscores the potential for pacemaker lead dislodgement into the left atrium through a patent foramen ovale.
- Retraction of left atrially dislodged pacemaker leads necessitates careful management, including full anticoagulation.
Abstract:
A 76-year-old woman had a permanent transvenous DDDR pacemaker implanted for complete atrioventricular block. She was hospitalized 4 years later for recurrent transient ischaemic attacks related to dislodgment of the atrial lead into the left atrium through a patent foramen ovale. The patient was successfuly treated by transvenous extraction of the atrial lead. The follow-up has been uneventful 12 months after the procedure. Left atrially dislodged pacemaker leads have to be retracted under full anticoagulation.

Electrocardiogram Fundamentals
An electrocardiogram (ECG) is a diagnostic tool for identifying cardiac conditions such as arrhythmias, conduction abnormalities, and myocardial ischemia.
Definition
An electrocardiogram (ECG) visualizes the heart's electrical activity by tracing the electrical movement associated with each heartbeat on a graph or monitor. As the heart beats, an electrical wave passes through it, correlating with the cardiac cycle events.
