Echocardiographic predictors of survival in low gradient aortic stenosis

Am J Cardiol. 2000 Oct 1;86(7):804-7, A10. doi: 10.1016/s0002-9149(00)01089-4.


Echocardiographic predictors of long-term survival for patients with low gradient aortic stenosis who undergo aortic valve replacement have not been previously reported. This study shows that patients with larger pre- and postoperative left ventricular volumes, a lower mean preoperative aortic pressure gradient, and failure of volumes to decrease and ejection fraction to increase postoperatively may have a poor prognosis.
