Echocardiographic Predictors of Reoperation for Subaortic Stenosis in Children and Adults

In this paper, the objective was to find out the echocardiographic predictors of reoperation for subaortic stenosis. Among 82 patients who initially underwent subaortic stenosis corrective surgery, 30 patients required reoperation. The risk factors were young age, unfavorable left ventricular geometry, interrupted aortic arch, and higher residual left ventricular outflow tract gradient.
