PO-02-134 REAL WORLD CLINICAL MANAGEMENT AFTER SURGICAL LEFT ATRIAL APPENDAGE EXCISION

Surgical left atrial appendage (LAA) closure is an increasingly utilized approach to mitigate the risk of cardioembolic stroke in patients with fibrillation (AF). Optimal prevention management after surgical LAA respect imaging and continuation oral anticoagulation (OAC) not well understood. To elucidate real world clinical undergoing management. Over a 7-year period at single center, 458 participants carried diagnosis AF underwent exclusion their during concomitant cardiac surgery. Clinical follow-up, including transesophageal echocardiography (TEE) data OAC use were catalogued via chart review. Success ligation was defined as maximal stump depth < 1.0 cm (with no distal leak) all dimensions imaged. Of participants, 115 (25%) had post-operative TEE average time 36 weeks). these patients, 95 discharged from surgery on 83/115 (72%) successful by criteria; 19/115 inadequate 13/115 did have sufficient image quality assess closure. Among 83 TEE-verified closure, 7 follow-up; strokes 3/7 occurred within 4 weeks Only 1/7 stroke. (Table 1) 70 been following 47/70 subsequently discontinued; 43/47 those discontinuations TEE. Most do receive follow-up imaging. When performed, excision shown moderate success rate. management, regard continuation, highly heterogeneous.
