Abstract:

OBJECTIVE

To evaluate effectiveness and safety of concomitant septal myectomy during aortic valve replacement in patients with severe aortic stenosis.

MATERIAL AND METHODS

We retrospectively analyzed 42 patients with severe aortic stenosis and interventricular septum hypertrophy over 1.5 cm. All patients underwent aortic valve replacement and concomitant septal myectomy.

RESULTS

There was a significant improvement in hemodynamic parameters in the left ventricular outflow tract (LVOT) and at the aortic valve prosthesis. Peak blood flow velocity decreased from 4.8±0.8 to 2.1±0.4 m/s (p<0.0005). Mean aortic valve pressure gradient decreased by 6 times up to 10.1±3.7 mm Hg (p<0.0005). Peak and mean LVOT pressure decreased from 9.0±7.8 to 5.0±1.9 mm Hg (p<0.0022) and from 4.4±3.0 to 2.7±1.0 mm Hg (p<0.0006), respectively. Complete heart block occurred in 2 patients (4.7%), and no iatrogenic ventricular septal defect was noted.

CONCLUSION

A surgeon should inspect the LVOT during aortic valve replacement and perform aortic valve replacement if necessary. Concomitant septal myectomy is a safe and effective procedure that improves hemodynamic parameters of the left ventricle.
