A rare cardiac thrombus formed on the intra-atrial septum after biventricular pacemaker implantation. Echocardiography confirmed the thrombus, which later resolved, likely due to embolization.
Area of Science:
- Cardiology
- Medical Imaging
Background:
- Ischaemic cardiomyopathy necessitates advanced cardiac device implantation.
- Biventricular pacemakers/defibrillators improve cardiac function but may pose procedural risks.
Observation:
- An immobile, echogenic mass was detected on the left atrial side of the fossa ovalis via echocardiography.
- This mass was absent in pre-procedural imaging, suggesting a post-implantation complication.
Findings:
- Contrast echocardiography and power Doppler confirmed the mass as a thrombus, lacking microcirculation and blood flow.
- The thrombus resolved spontaneously by follow-up echocardiography, presumed due to peripheral embolization.
Implications:
- This case highlights a potential complication of biventricular device implantation.
- Echocardiography is crucial for diagnosing and monitoring cardiac masses post-procedure.
- Understanding thrombus resolution mechanisms is important for patient management.
