| Popis: | Aim. Comparative analysis of the acquired with EchoCG method parameters of the left chambers of the heart and of mitral valve in normal state and in restrictive type of failure with further building up three-dimensional models of these variants of the fibrous anulus geometry, and of the left atrium, left ventricle and its outgoing tract.Material and methods. The study was done using 3D transthoracal and transesophageal EchoCG on Philips iE33 (Philips Healthcare, USA) in 30 patients with unchanged mitral valve (n=15) and in ischemic mitral regurgitation (n=15). Spatial configuration of the anulus fibrosus was investigated, and mitral valve, spatial and volumetric parameters of the left atrium and left ventricle. Data was processed in SciLab 4.1.2 software and exported to CATIA 5 modelling system, where the acquired curves were combined to 2 solid thin-wall models, and after linking of the surfaces — to a hard-bodied model with required thickness of the walls.Results. All studied parameters revealed significant differences (p |
