Key result
Gore Helex Septal Occluder successfully closes a large residual gap after LARIAT LAA suture ligation.
Why the study?
Residual leaks after percutaneous left atrial appendage suture ligation can preclude cessation of anticoagulation, and novel closure approaches are needed.
Case Report (n=1)
This case report demonstrates the feasibility of using a septal occluder to close a residual leak after a LARIAT procedure for left atrial appendage ligation.
May offer bailout for residual LAA leaks post-LARIAT; hypothesis-generating and requires prospective validation before adoption.
Percutaneous left atrial appendage suture ligation with the LARIAT® device (Sentre HEART, Redwood City, CA) was successfully performed on an 84-year-old woman with non-valvular atrial fibrillation who developed intracranial hemorrhage on warfarin. However, a large gap developed at follow-up precluding warfarin cessation. To the best of our knowledge, this case report represents the first description of the use of a Gore® Helex® Septal Occluder (W. L. Gore and Associates, Newark, Delaware) as a novel approach to close a gap following percutaneous LAA suture ligation.

Yeow et al. (2013) conducted a case report in Non-valvular atrial fibrillation with residual leak following LARIAT procedure (n=1). Gore Helex Septal Occluder was evaluated on Closure of residual leak. A Gore Helex Septal Occluder was successfully used to close a large residual gap following percutaneous left atrial appendage suture ligation with the LARIAT device.
