Insights
Routine imaging after left atrial appendage closure monitors device success and detects complications like leaks or clots. Early detection guides further treatment, ensuring patient safety and optimal outcomes.
Area of Science:
- Cardiology
- Medical Imaging
Background:
- Left atrial appendage (LAA) closure is a common procedure for stroke prevention in patients with atrial fibrillation.
- Effective postprocedural surveillance is crucial for monitoring device performance and patient safety.
Purpose of the Study:
- To outline the role and importance of routine postprocedural imaging in LAA closure.
- To highlight the key findings and potential complications detectable via imaging.
Main Methods:
- Routine imaging surveillance using transesophageal echocardiography (TEE) or cardiac computed tomography angiography (CCTA).
- Follow-up typically occurs 1 to 6 months after the LAA closure procedure.
Main Results:
- Imaging confirms proper device placement and sealing within the LAA.
- Detection of potential complications including peri-device leaks, device-related thrombus, and device embolization.
Conclusions:
- Postprocedural imaging is essential for assessing LAA device success and identifying adverse events.
- Findings from imaging dictate subsequent management, such as continued surveillance, anticoagulation, or further 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.
