Abstract


The aortal stenosis is the most widespread diseases among valvate damages of heart. The hypertrophy of the left ventricle which degree correlates with weight of the defect in many respects defines outcomes of an aortal stenosis. Thus in the literature there is no precise communication between in thickness myocardium left ventriculum and initial valve the device (the size of a ring aortic the valve), as well as speeds of regress of a hypertrophy in the postoperative period and the size of an implanted artificial limb. In work the analysis of dynamics of haemodynamic parameters of heart in a perioperating period depending on anatomic features of the valvate device is carried out (the diameter of a ring aortic the valve). In surgical practice at implantation of an aortal artificial limb estimate body surface area, thus try to provide as much as possible physiological needs for warm emission. Therefore most often to them plan artificial limbs the sizes more than №23. However owing to expressiveness of a kaltsinoz of an aortal ring and deformation it owing to fibrosis it is not always possible to establish artificial limbs of the corresponding diameter. Our research is directed on detection of features of haemodynamic indicators in postoperative the period, as forecast predictors depending on diameter of an aortal artificial limb. It is established, that patients with implantation of prosthetic appliance sizes №19-23 in early operational period had a higher gradient of pressure on an aortic valve, more slow reduction of degree of hypertrophy of myocardium as compared to the group of patients with prosthetic appliances more than № 23. At comparison hemodynamic parameters of both groups in the remote timeframes the increase of a gradient of pressure of an artificial limb aortic the valve in group with artificial limbs less than №23 in comparison with preoperative periods is revealed. At patients with artificial limbs more than № 23 intracardial characteristics in the remote period especially did not change. The given features, probably, are connected with shaped dysfunction of an artificial limb (pannus) or with more expressed load on left ventriculum (at slower regress of a hypertrophy left ventricuulum), that the trancevalve a gradient of pressure tends to increase.
