[The characteristics of the intracardiac hemodynamics in hypertrophic cardiomyopathy: the role of cine-magnetic resonance tomography].

Cine-magnetic resonance (CMR) tomography was assessed for ability to determine cardiac function and structure in patients with hypertrophic cardiomyopathy (HTCM). CMR tomography findings were compared to those of two-dimension and doppler-echocardiography, cardiac catheterization. The trial entered 16 patients with obstructive, 22 patients with nonobstructive HTCM and 14 healthy controls. CMR tomography was performed on a superconducting tomograph (1.5 T) in synchronism with ECG. CMR tomography helped detect obstruction for the blood outflowing from the left ventricle. This was impossible with the use of spin-echo. It also defined area and volume of low-intensity regions. CMR tomography proved sensitive in bringing out mitral regurgitation, the results being close to those of doppler-echocardiography. Opportunities of MRT in HTCM gets expanded in cine-regimen as it provides additional information on cardiac function and intracardiac hemodynamics.
