Left atrial ejection force correlates with left atrial strain and volume-based functional properties as assessed by three-dimensional speckle tracking echocardiography (from the MAGYAR-Healthy Study)
INTRODUCTION AND OBJECTIVE: Three-dimensional (3D) speckle tracking echocardiography (3DSTE) is a novel method for assessment of left atrial (LA) volumes and function without geometrical assumptions. 3DSTE allows detailed assessment of LA features including volume measurements, strain assessments an...

| 520 | 3 | |a INTRODUCTION AND OBJECTIVE: Three-dimensional (3D) speckle tracking echocardiography (3DSTE) is a novel method for assessment of left atrial (LA) volumes and function without geometrical assumptions. 3DSTE allows detailed assessment of LA features including volume measurements, strain assessments and calculation of LA ejection force (LAEF). LA strain and volume-based functional parameters originate from the same 3D dataset, but assessment of LAEF requires more data including measurement of mitral annular dimensions and Doppler-derived inflow velocities. The present study was designed to find correlations between LAEF and 3DSTE-derived LA volume-based functional properties and strain parameters in healthy subjects. METHODS: The study population comprised 34 randomly selected healthy subjects (age 36.1+/-11.2 years, 15 men) in sinus rhythm, all of whom had undergone standard two-dimensional transthoracic Doppler echocardiographic study extended with 3DSTE. RESULTS: Mitral annulus diameter-based LAEF correlated with global LA peak circumferential (r=0.39, p=0.02), longitudinal (r=0.32, p=0.05) and area (r=0.43, p=0.01) strain, total atrial stroke volume (r=0.30, p=0.05) and total atrial emptying fraction (r=0.31, p=0.05) characterizing (systolic) LA reservoir function and global LA 3D strain at atrial contraction (r=-0.44, p=0.01) and active atrial emptying fraction (r=0.36, p=0.04) characterizing (diastolic) LA contraction function (booster pump phase). CONCLUSIONS: Complex LA functional assessment can be provided by 3DSTE, including calculation of LAEF and volume-based and strain functional properties, with significant correlations between these parameters. | |
