Fig 1 Increasing complexity of surgery through the surgical history of the patients. (AVR = aortic valve replacement; SAS = subaortic stenosis; 1 = subaortic ridge resection; 2 = redo subaortic ridge resection; 3 = subaortic ridge resection plus aortic valve replacement.)

Fig 2 Effect of subaortic stenosis surgery on left ventricular outflow tract (LVOT) velocity. (A) Group 1 (first-time subaortic stenosis resection). (B) Group 2 (redo subaortic stenosis resection). Left ventricular outflow tract velocities are significantly reduced after surgery (p < 0.001). (Post-Op = postoperatively; Pre-Op = preoperatively.)
