leadless cardiac pacemaker
Intracardialer
Herzschrittmacher im rechten Ventrikel. Dabei erheblich dilatiertes rechtes Herz. Koronar (links) sehr weich gefenstert.
Intrakardialer
Herzschrittmacher im rechten Ventrikel Medtronic Micra. Zusätzlich sehr ausgeprägter Kalk der Mitralklappe.

nicht verwechseln mit: EventrecorderLeadless cardiac pacemakers are a recently introduced type of cardiac conduction device. These pacemakers are self-contained right ventricular single-chamber pacemakers that are implanted percutaneously via a femoral approach . There are currently two leadless cardiac pacemakers on the market: Nanostim™️ (Abbott Medical) and Micra™️ (Medtronic).
Radiographic features
A leadless cardiac pacemaker can be appreciated on plain chest radiographs or CT scans as a radiolucent oblong-shaped small device in the right ventricle . It is important to not mistake this device, especially on a PA view plain radiograph, for the similarly-shaped implantable loop recorder .
Depending on the brand, the exact size varies :
- Nanostim Leadless Cardiac Pacemaker (Nanostim LCP): 4.2 cm x 0.6 cm
- Micra™️ Transcatheter Pacing System (Micra™️ TPS): 2.6 cm x 0.7 cm
Both devices are compatible with 1.5 T and 3 T body MRI .
