Case Report: Successful retrieval of a migrated left atrial appendage occluder through the synergistic use of a guidewire and a gooseneck snare [PDF]

Frontiers in Cardiovascular Medicine
Left atrial appendage occluder (LAAO) dislodgement with embolization is a rare occurrence. If the LAAO migrates into the left atrium or ventricle, it can lead to acute heart failure or even death in a person, necessitating urgent surgical intervention ...

In silico Optimization of Left Atrial Appendage Occluder Implantation Using Interactive and Modeling Tools [PDF]

Frontiers in Physiology, 2019
According to clinical studies, around one third of patients with atrial fibrillation (AF) will suffer a stroke during their lifetime. Between 70 and 90% of these strokes are caused by thrombus formed in the left atrial appendage.

Late discovery of left atrial appendage occluder device embolization: a case report [PDF]

BMC Cardiovascular Disorders, 2020
Background Left atrial appendage (LAA) closure has been well evaluated in the prevention of stroke in patients with atrial fibrillation. Device embolization remains one of the most common complications.

Application of the combined technique of novel transseptal puncture guidewire and steerable sheath in left atrial appendage occlusion: a preliminary feasibility case series [PDF]

Frontiers in Cardiovascular Medicine
ObjectiveTransseptal puncture (TSP) is a critical step in left atrial appendage occlusion (LAAO) but presents certain technical challenges. Conventional puncture needles, due to their inherent rigidity, often cause unpredictable needle tip “bouncing” or ...
