TAPSE of 6.6 mm and RVFAC of 32%, RVEF as measured using 3D analysis had improved to 34.9% (Fig. 2), which was close to the low reference value of RVEF. The 2D and 3D measurements were performed with the RVAD flow rate decreased to less than 0.5 L/min, continuous administration of dobutamine 5 mug/kg/min, and decreased mechanical ventilation.
