Background: Aortic valve stenosis causes gradual obstruction to left ventricular outflow tract. It is a common valvular disease that carries many life threatening complications. We hypothesized that the reduction or elimination of the pressure gradient across the aortic valve after correction of the stenotic lesion would lead to regression of left ventricular mass and improve left ventricular functions. Aim of the work is to assess the effectiveness of the correction and factors controlling these changes in left ventricular mass index and functions. Methods: preoperative and postoperative Electro-cardiography and echocardiography were performed for all patients. The corrective procedures included aortic valve replacement, balloon aortic valvuloplasty and open valve repair. Results: Sixty patients had correction of aortic valve stenosis (44 males, 16 females). ECG score preoperatively ranged between3 and 9 with a mean of 6 ± 1.63. Postoperatively, it ranged between 0 and 6 and mean of 3 ± 0.7. The mean LVED/BSA was reduced from 32.52 preoperatively to 30.41 postoperatively. The mean interventricular septal thickness index was reduced by 1.03. The mean left ventricular posterior wall thickness index was reduced by 0.99. Mean left ventricular mass index was reduced by 31.86 gm. The mean ejection fraction increased by 6.45. Mean trans-aortic peak gradient was reduced by 41.36 mmHg. Conclusions: Correction of aortic valve stenosis improves systolic and diastolic left ventricular function and a reduction in left ventricular mass index. Aortic root enlargement procedures can be safely avoided.
