Insights
Routine imaging like echocardiography or CT angiography monitors left atrial appendage devices 1-6 months post-procedure. This follow-up detects device issues and complications, guiding further treatment and surveillance.
Area of Science:
- Cardiology
- Medical Imaging
Background:
- Left atrial appendage closure is a common procedure for stroke prevention.
- Effective post-procedural surveillance is crucial for patient safety and device efficacy.
Purpose of the Study:
- To outline the standard imaging modalities and timing for post-procedural surveillance of left atrial appendage devices.
- To highlight the importance of imaging in identifying device-related complications.
Main Methods:
- Routine imaging, including transesophageal echocardiography and cardiac computed tomography angiography, is employed.
- Surveillance is typically conducted 1 to 6 months after the initial procedure.
Main Results:
- Imaging confirms proper device placement and sealing within the left atrial appendage.
- Potential complications such as peri-device leaks, device-related thrombus, and device embolization are identified.
Conclusions:
- Post-procedural imaging is essential for monitoring left atrial appendage device success and safety.
- Early detection of complications through imaging guides subsequent management, including further surveillance, anticoagulation, or interventions.
Abstract:
Routine postprocedural imaging with transesophageal echocardiography or cardiac computed tomography angiography is the most commonly used imaging modality for follow-up surveillance usually performed 1 to 6 months after the procedure. Imaging enables recognition of well-suited and sealed devices in the left atrial appendage as well as of potential harmful complications such as peri-device leaks, device-related thrombus, and device embolization, which may lead to further surveillance observation with recurrent imaging, reinitiation of oral anticoagulants, or additional interventional procedures.
