Key result
TEE speckle tracking shows diffusely decreased LAA deformability and compliance in persistent versus paroxysmal AF.
Why the study?
LAA dysfunction is closely associated with AF-related stroke, but few studies have evaluated changes in LAA function across different types of AF.
Does transesophageal echocardiography combined with two-dimensional speckle tracking detect differences in left atrial appendage function between paroxysmal and persistent non-valvular atrial fibrillation?

May refine AF subtype phenotyping on TEE speckle tracking; leaves open whether measures predict outcomes or alter management.

Does transesophageal echocardiography combined with two-dimensional speckle tracking detect differences in left atrial appendage function between paroxysmal and persistent non-valvular atrial fibrillation?
p-value: p=0.000
Transesophageal echocardiography with speckle tracking demonstrates that left atrial appendage deformability and compliance are significantly more impaired in persistent compared to paroxysmal non-valvular atrial fibrillation.
Wang et al. (2022) conducted an observational in non-valvular atrial fibrillation (n=216). Transesophageal echocardiography combined with two-dimensional speckle tracking vs. Different types of atrial fibrillation (persistent vs paroxysmal) was evaluated on Left atrial appendage systolic motion and function (strain values and mechanical dispersion) (p=0.000). Transesophageal echocardiography with speckle tracking demonstrated that left atrial appendage deformability and compliance are decreased diffusely in persistent AF compared to paroxysmal AF.
