B-po04-077 heart rate variability and left atrial hemodynamics in atrial fibrillation measured with 4d flow mri

Atrial fibrillation (AF) can lead to stroke due to thrombus formation in the left atrium (LA) or left atrial appendage (LAA). Altered LA hemodynamics in the presence of AF may be predictive of thrombus and stroke risk. Previous 4D flow MRI studies found increased stasis and decreased peak velocity in patients with AF. However, the impact of variable R-R intervals on LA velocity and stasis measurement has not been investigated.
