Changes in echocardiographic parameters during follow-up period. a. Changes in LVIDd during follow-up. b. Changes in IVS thickness during follow-up. c. Changes in LVOTG during follow-up. There was significant decrease in LVOTG at 2.5 years and 5 years after surgery. d. Changes in EF during follow-up. EF was elevated at 2.5 years and 5 years after extensive septal myectomy. LVIDd: diastole left ventricular inner diameter; IVS: interventricular septal; LVOTG: left ventricular out tract gradient; EF: ejection fraction. *P < 0.05 vs preoperative group, #P < 0.05 vs 2.5 years group
