Video Supplement for Complex Left Atrial Appendage Occlusion Using the Novel Amplatzer Steerable Delivery Sheath by Muiños, et al. (March 2023 Clinical Images)

Left atrial appendage (LAA) occlusion has emerged as an alternative to oral anticoagulation in non-valvular atrial fibrillation. The success rate is high, but we are still facing some challenging LAA anatomies that may increase the risk of suboptimal results. Coaxiality between the delivery sheath and the LAA neck is therefore crucial. Nevertheless, even with an optimal transseptal puncture, some LAA morphologies imply some difficulties. The novel Amplatzer steerable delivery sheath (Abbott Cardiovascular) offers the possibility of deflecting the distal end in a wide spectrum of angles from 0º to 120º.
