Background: Aortic valve disease is associated with eccentric or concentric left ventricular (LV)hypertrophy and changes in the LV mass. The relationship between LV mass and function and theeffect of LV remodeling after aortic valve replacement (AVR), in patients with aortic valvedisease needs evaluation, that is largely unknown in our population. The aim of this study was toevaluate the effect of AVR on LV remodeling, in patients with aortic valve disease. Methods:Fifty patients with aortic valve disease were studied using transthoracic echocardiography toassess LV mass before AVR and compared with early postoperative changes in the LVdimensions and function. LV mass was studied preoperatively and before discharge in 50consecutive patients undergoing isolated aortic valve replacement. Results: Out of fifty patients,47(94%) were male and 03(6%) were female. Mean age of the patients was 40.42 years. 22 (44%)had isolated aortic stenosis (AS), 16 (32%) patients had isolated aortic regurgitation (AR) and 12(24%) patients had mixed aortic valve disease (MAVD). 02 (4%) patients died. LV massregression was studied in all the patients. In group A, with aortic stenosis, LV regressed to 69.88gm (mean) with maximum of 156.88 gms and minimum of 0.00 gms (SD 43.67 gms, p value =0.001). In group B, with aortic regurgitation, LV mass regressed to 203.96 gms (mean) withmaximum 453.79 gms and minimum of 45.65 gms (SD 95.33, p value = <0.001). In group C, withmixed aortic valve disease, postoperatively LV mass regressed to 122.94 gms (mean) withminimum 9.57 and maximum of 224.75 gms (SD 69.53, p value = 0.524). Conclusion: There wassignificant early LV mass regression after aortic valve replacement in patients with pre existingaortic valve disease. However, it was noticed that LV mass regressed in all patients except nosignificant changes in LV wall thickness (hypertrophy).Keywords: Aortic valve replacements; Left ventricular mass regression; Left ventricular function.
