Leadless cardiac pacemaker

Case contributed by Marianne Cossens
Diagnosis certain

Presentation

Chest pain and dyspnea

Patient Data

Age: 70 years
Gender: Male
x-ray

Rectangular intracardiac pacemaker device projected over the right ventricle.

Left atrial occluder device positioned within the left atrial appendage, a Watchman device.

Right atrial and right ventricular retained cardiac pacemaker tips, from the previous left pectoral dual lead pacemaker. See subsequent radiograph.

Internal fixation of the sternum with wires, plate and screws.

Case Discussion

The leadless cardiac pacemaker is not to be mistaken for an implantable loop recorder device, which is positioned in the subcutaneous tissues of the chest. The lateral radiograph confirms this device is intracardiac.

The dual lead pacemaker was removed due to infected leads.
