4 Figure 3 Predicted follow-up LVOT resting gradient in myectomy and ASA cases, based on preprocedure gradients. A, Predicted postprocedural gradients using catheter/pressure measurements. B and C, Predicted early (<30 days after procedure) and late transthoracic echocardiography gradients (>30 days to 2 years after septal reduction therapy). LVOT, Left ventricular outflow tract; TTE, transthoracic echocardiography.
