Transesophageal echocardiography is essential for guiding Amplatzer Amulet LAA occlusion device placement, confirming occlusion, and detecting complications, especially in patients with renal insufficiency.
Supports TEE guidance for Amulet LAAO in renal insufficiency; leaves open prospective validation of outcomes.
In this report, we provided details of periprocedural echocardiographic guidance for patients undergoing Amplatzer-Amulet device left atrial closure. Familiarity with left atrial appendage (LAA) occlusion devices and the required left atrial examination and measurements are key before device placement. Device placement is assisted by transesophageal echocardiography (TEE) and fluoroscopy, but TEE will be the main guide for patients with renal insufficiency in whom contrast dye use needs to be minimal. TEE is also used to confirm LAA occlusion with the device and finally detect complications throughout the procedure and into the postoperative period.
