Complex Left Atrial Appendage Occlusion Using the Novel Amplatzer Steerable Delivery Sheath.

Left atrial appendage (LAA) occlusion has emerged as an al- ternative to oral anticoagulation in non-valvular atrial fibril- lation. The success rate is high, but we are still facing some challenging LAA anatomies that may increase the risk of sub- optimal results. These images show that the Amplatzer steer- able sheath is useful for LAA occlusion, especially in cases with challenging anatomies. Small variations of the distal end angle can improve the success rate and reduce complications.
