BACKGROUND: Percutaneous left atrial appendage (LAA) closure has emerged as an alternative therapeutic option for the prevention of embolic stroke in high-risk patients with non-valvular atrial fibrillation. The presence of thrombus in the LAA is currently a contraindication to the procedure.
AIM: To describe a modified LAA closure technique that allows a safe procedure in patients with LAA thrombus.
METHODS: Between May 2013 and October 2014, LAA closure was performed in three patients with LAA thrombus (mean age 73.6±14 years; two men), using a modified technique that avoids manipulation of catheters or angiography in the LAA.
RESULTS: Two patients had persistent thrombus despite appropriate antithrombotic therapy, while the other patient had a contraindication to systemic anticoagulation. The procedure was successful using the modified implantation technique in all patients. The implanted device was the AMPLATZER™ Cardiac Plug (St. Jude Medical, Minneapolis, MN, USA) in one patient and the Amulet™ (St. Jude Medical, Minneapolis, MN, USA) in two patients. No periprocedural complications occurred. After a mean follow-up of 8±2 months, no deaths or late complications were observed.
CONCLUSIONS: Thrombus trapping is a feasible and effective technique for performing LAA occlusion in patients with thrombus within the LAA. This modification of the implantation technique may allow LAA closure indications to be extended to include patients with LAA thrombus, who were formerly considered unsuitable.
