Insights
Left atrial appendage (LAA) ligation can reduce stroke risk in atrial fibrillation patients. This report highlights an under-utilized echocardiography method to improve LAA visualization during this minimally invasive procedure.
Area of Science:
- Cardiology
- Medical Imaging
- Surgical Procedures
Background:
- Atrial fibrillation is a common arrhythmia associated with increased risk of stroke.
- Left atrial appendage (LAA) ligation is a procedure to mitigate this risk by isolating the LAA.
- Successful LAA ligation, often performed via thoracoscopic surgery, relies on precise visualization.
Abstract:
Left atrial appendage (LAA) ligation is procedure which isolates the LAA and can decrease the risk of thrombus and arrhythmias in patients with atrial fibrillation, allowing patients to come off home anticoagulation medications. This procedure can be done through minimally invasive thoracoscopic surgery and requires guidance by transesophageal echocardiography. Visualization of the LAA and associated intrathoracic structures is vital for the success of the procedure. This echo rounds report describes an under-utilized method for LAA assessment to encourage cardiac anesthesiologists to consider employing it to increase their ability to completely evaluate the LAA.
