【 摘 要 】

Modern times, surgeons of the entire world utilize the technics of left ventricular reconstruction (LVR) developed by professor Dor V. However, oftenly the left ventricle (LV) presents with a spheric shape in postoperation period, by echocardiography. When, normally, geometry of the LV is conceptualized as a stretched ellipse with longitudinal axis directed from apex to the base of the heart.Aim. To evaluate effectiveness of modified LVR using Z-suture to create the LV apex in patients with postinfarction heart aneurysms.Material and methods. Twelve patients with anterior-septal localization of the LV aneurysm having myocardial infarction in anamnesis more than 6 months, with LV ejection fraction less 45%, underwent the modified LVR with Z-suture. Efficacy of the correction was assessed by echocardiography data in short term period till 1 month after the operation, comparing with pre-surgery data.Results. In all patients surgery proceeded successfully. Sphericity index significantly decreased in diastolic phase at basal level from 0,83±0,17 to 0,63±0,11 (p=0,05) and at apical level from 0,56±0,12 to 0,37±0,09 (p=0,01). Conical index increased at basal level from 1,26±0,06 to 1,67±0,40 (p=0,05), at middle-apical level from 1,34±0,30 to 1,4±0,34 (p=0,05).Conclusion. The modified left ventricular reconstruction with Z-suture forms the ellipsoid heart shape and is an effective method of surgery of postinfarction LV aneurysm.
