Subendocardial flow index may correlate with symptoms in subvalvar aortic stenosis; hypothesis-generating and should not yet change practice.
Does the subendocardial flow index correlate with clinical and hemodynamic parameters in patients with discrete subvalvar aortic stenosis?
Calculation of the subendocardial flow index may be a useful additional variable in determining the timing of surgery for patients with discrete subvalvar aortic stenosis and borderline indications.
Cassel et al. (1978) studied this question.
