Fig 2 Results of hemodynamic cardiac catheterization. (A) Before operation, increased right ventricular end-diastolic pressure, and left ventricular end-diastolic pressure with a square root sign. (B) After operation, decrease in ventricular end-diastolic pressure, but persistence of square root sign.
