Abstract

Aim: To study left atrial (LA) deformation in patients with arterial hypertension, aortic stenosis (AS) and left ventricular hypertrophy (LVH) of different severity. Material and methods: LA deformation was studied in 20 healthy subjects and 68 patients. Of them 30 patients had AH and mild LVH, 22-AH and manifest LVH, 16 patients had AS. Standard echocardiography (EchoCG) was made and then analysed with the method of two-dimentional seroscale deformation (TDSD). Segmentory maximal deformation was estimated in 5 middle segments of left atrial walls, middle maximal deformation was determined in 4- and 2-chamber positions, global maximal deformation were evaluated in left atrial contraction and accumulation phases. Results: Due to pressure-induced overloading, L VH was accompanied with abnormal left atrial deformation, AH patients demonstrated decreased deformation even in mild LVH. AS was associated with most pronounced changes of left atrial deformation. Abnormal left atrial deformation in AH and AS was more significant in accumulation phase. In contraction phase, left atrial deformation deterioration occurred only in AS. Conclusion: Conduction of TDSD enables analysis of atrial deformation and opens wide perspectives for further investigations aimed at better understanding of changes in the atria.
