THE LEFT ATRIAL APPENDAGE MORPHOLOGY IN PATIENTS WITH ATRIAL FIBRILLATION BY CARDIAC COMPUTED TOMOGRAPHY

Tóm tắt

Purpose: To describe the morphological characteristics of left atrial appendage (LAA) on multislice computed tomography in patients with atrial fibrillation. Materials and methods: A prospective descriptive study on 44 patients diagnosed with atrial fibrillation (AF) and underwent multislice computed tomography at Bach Mai Hospital from August 2022 to July 2023.

Results: Mean age 64.45 ± 10.50. The most common morphology of LAA is “windsock” with 40.91%, followed by “chicken wing” with 34.09%, then “cauliflower” with 13.64%, and finally “cactus” with 11.36%. The most common LAA orifice position is in the middle (63.64%), the average length of the LAA is 47.03 ± 11.69 mm, and the mean volume of the LAA is 14.39 ± 8.00 ml. There is little relationship between gender and morphological characteristics of the LAA.

Conclusion: The most common LAA morphology in patients with atrial fibrillation is “windsock”. Gender has little association with left atrial appendage morphology.
