title: [X-ray evaluation of the results of mitral valve bioprostheses].
abstract: An analysis of results of investigations performed in 66 patients has shown that roentgenometric examinations facilitate obtaining an objective estimation of the dynamics of postoperative period in patients with bioprostheses of the mitral valve. After performing such operations many roentgenological signs of the defect undergo involution, the duration of the process being determined by the character of the defect and the initial state of the myocardium. The dynamics of volumetric alterations of the heart were shown to reflect specific functioning of the bioprosthesis.
