ASSOCIATION ANALYSIS BETWEEN LEFT ATRIAL FUNCTION AND LEFT ATRIAL APPENDAGE FUNCTION IN PATIENTS WITH NONVALVULAR ATRIAL FIBRILLATION

The left atrial appendage (LAA) is a common source of cardiac thrombus with nonvalvular atrial fibrillation(NVAF). It is unclear about the relationship between left atrial (LA) function and LAA function in patients with NVAF. We analyzed LA function using speckle tracking method and LAA function
