Abstract
Preface. The manifestation of pathological deformation of the heart in the condition of mitral valve anomalies influences the intensity
of the heart geometry recovery at late dates after surgical repair which is why its estimation has the great importance for prognosis of
the late outcomes of surgical treatment.
Material and methods. 30 patients were included in the research, 10 patients out of them comprised the control group of practically
healthy persons and 20 patients with acquired mitral valve defects comprised the main group. Patients were examined with the magnetic
resonance tomograph Magnetom Avanto 1.5 Tesla of Siemens and ultrasound apparatus HDI, Acuson and Sonos 2500 of Hewlett
Packard by means of transthoracic gauges of 2.5 and 3.5 MHz in one-dimensional and two-dimensional modes.
Results. In order to verify the received records the comparative analysis has been conducted regarding the volumes of the heart chambers
gauged by methods of echocardiography and magnetic resonance tomography in healthy patients in the control group which
allowed to estimate the value difference in structural-geometric parameters between methods not only under the pathology but also
under the normal conditions. The following main factors affecting this difference have been revealed and analysed: cardiac cycle phase,
degree of pathological remodeling of heart chambers, difference in method technology insuring adjusted anatomical slices.
Conclusion. The value of difference between records received by the methods of echocardiography and magnetic resonance tomography
depends on the phase of cardiac cycle, extent of manifestation of pathologic remodeling and adjustment of anatomical slices.
