ABSTRACT
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
