Alternative ways to assess left atrial function in noncompaction cardiomyopathy by three-dimensional speckle-tracking echocardiography

Advances in the assessment of left atrial function by three-dimensional speckle tracking echocardiography

“…RT3DE-derived MAD and MAA proved to be larger in case of cardiomyopathy, while it was associated with more significant MA function in HCM, MA function proved to be reduced in dilated and noncompaction cardiomyopathy (9,10 ). Up to the present the available literature dealing with 3DSTE is limited, but it seems to be a suitable procedure for calculation of MA morphological and functional parameters (40).…”

Focus on atrial function: benefits of three-dimensional speckle-tracking echocardiography

“…LAEFO is based on classic Newtonian mechanics and is a potential useful index for assessing atrial contribution to diastolic performance (28). Over 2D imaging both 3D echocardiographic techniques, RT3DE (14,21,37) and 3DSTE (13) have been demonstrated to be practicable in assessing LAEFO using Doppler-derived mitral inflow A velocity. However, to the best of authors' knowledge this is the first time to examine whether correlations exist between 3DSTE-derived LAEFO and LA volume-based and strain funtional properties respecting cardiac systolic and diastolic functions in healthy subjects.…”

“…There are several ways for functional assessment of LA including calculation of volumebased and strain parameters by 3DSTE as demonstrated before (6,(8)(9)(10)(11)(12)(13). With these parameters detailed characterization of all three LA functions possible:…”

“…In earlier studies 3DSTE was revealed for detailed assessment of all LA features including volumetric measurements (6,(8)(9)(10), strain assessments (10-12) and calculation of LA ejection force (LAEFO) (13). LA strain and volume-based functional parameters originate from the same 3D dataset, but assessment of LAEFO requires more data including measurement of mitral annular dimensions and Doppler-derived inflow velocities (14).…”

“…It usually presents with ventricular dysfunction, thromboembolic events and arrhythmias. However, little is known about the behaviour of LA in noncompaction cardiomyopathy (NCCM) (13,21).…”
