DYNAMICS OF LEFT VENTRICLE PARAMETERS AFTER CORRECTION OF MITRAL AND AORTIC VALVE DISEASE

Abstract

The study assessed the dynamics of myocardial dimensions, mass, left ventricle (LV) systolic function and index of relative wall thickness in 64 patients in long-term follow-up after mitral and aortic valve replacement. An association between the extent of LV myocardium mass regression and specific features of LV geometry and the degree of hypertrophy. Ln 77.8 % of patients with LV myocardium mass index of > 20g/sq m, its hypertrophy was preserved after surgery, whereas impaired systolic function in 41 % >. LV myocardium mass neither returned to normal values with the index of relative wall thickness being less than 0.35. No satisfactory result was shown in patients with LV end diastolic size of 7. 0 cm or more. The results highlight the importance of timely pre-operative evaluation of LV structural and geometric parameters.
