Frequency of early remodeling of left ventricle and its comparison between patients with stroke volume ≥97 Ml versus patients with stroke volume <97 Ml after aortic valve replacement for severe aortic regurgitation

Objectives: to evaluate the frequency of early remodeling in patients of severe aortic regurgitation after aortic valve replacement and to see the incidence of early remodeling in patients with stroke volume ≥97 ml versus < 97 ml before aortic valve replacement. method: this was a prospective comparative study conducted from august 2013 to december 2014 in a tertiary care hospital. fifty seven (57) patients of isolated chronic aortic regurgitation were included in this study. spss v23 was used for data analysis. independent sample t-test was used for analysis of continuous variables and chi-square test for qualitative variables. results: out of fifty seven patients,early remodeling occurred in 34 (59.64%) patients after surgery. the mean pre-operative stroke volume of patient in whom remodeling occurred was 110.3±9.66 ml while mean pre-operative stroke volume of patients who did not undergo remodeling was 86.65±7.63 ml. there were 28 (82.4%) patients with stroke volume >97 ml in whom remodeling occurred where as in patients with stroke volume <97 ml remodeling occurred only in 6 (17.6%) patients (p value 0.004). there was no inhospital mortality. conclusion: there is an association between stroke volume and early lv remodeling after aortic valve replacement. stroke volume >97 ml is a good predictor of early lv remodeling. © 2016,professional medical publications. all rights reserved.
