Computational fluid dynamics analysis of blood flow patterns aims to identify left atrial appendage geometries that promote thrombus formation during atrial fibrillation.
Do specific left atrial geometries promote thrombus formation in the left atrial appendage under atrial fibrillation compared to normal rhythm?
Computational fluid dynamics can be utilized to identify specific left atrial appendage geometries that are prone to thrombus formation during atrial fibrillation.

A cerebral infarction occurs when a blood vessel in the brain becomes occluded by a thrombus, blocking the flow of blood. A thrombus formed in the heart can travel through the bloodstream and obstruct cerebral vessels. Such thrombi often develop in the left atrium during atrial fibrillation, particularly within a protruding, pouch-like structure known as the left atrial appendage(LAA). Computational Fluid Dynamics (CFD) analyses of blood flow in the left atrium under both normal rhythm and atrial fibrillation have been employed in previous studies. The aim of the present study is to identify left atrial geometries that promote thrombus formation in the left atrial appendage by comparing blood flow patterns between normal and fibrillating boundary conditions.
