Abstract

Aim. To study the frequency and validity of posterior aortoplasty for bioprosthetics of the aortic valve.

Materials and methods. To study the problem of the required aortoplasty frequency and reliability of the study, 99 patients with Neo-Cor “Uniline” 21-size bioprosthesis implantation were selected. According to the presence/absence of posterior arthroplasty, patients were divided into two groups. In the postoperative period the groups were compared according to the following criteria: left ventricular end-diastolic volume (LV EDV), ejection fraction (LV EF), stroke volume (LV SV), peak and mean valve gradients. Following parameters were calculated stroke volume index (SVI) and valve effective orifice area index (EOAI).

Results. There were no significant differences in postoperative data between the groups. In the group without an aortic aneurysm, left ventricular end-diastolic volume (LV EDV), stroke volume (LV SV), peak and mean valve gradients. were slightly larger. In the second group, ejection fraction (LV EF), and peripheral perfusion index were slightly larger. Which with lower gradients on the valve indicates more optimal contractility of the left ventricle.

Conclusion. In our practice in all cases, posterior aortoplasty was performed as indicated. Group of patients with aortoplasty demonstrated more optimal left ventricle function. Probably aortoplasty is to be applied more frequently.
