Table 2.

Vorticity and Helicity

Variable	Helicity (m/s²)		Vorticity (1/s) (×100)
Variable	PH Group (n=35)	Control Group (n=10)	PH Group (n=35)	Control Group (n=10)
MPA	8 (6–17)	32 (21–35)^a	13.4 (11.9–18.7)	14.8 (13.3–16.9)
RVOT+MPA	15 (11–34)	42 (40–48)^a	20.0 (16.0–23.9)	21.7 (19.0–24.1)
RPA	24 (15–33)	50 (42–57)^a	26.0 (17.2–31.2)	44.9 (42.7–54.5)^a
Total	46 (27–66)	92 (86–98)^a	60.2 (49.5–71.6)	85.6 (76.5–92.8)^a

Data are reported as median (interquartile range). MPA indicates main pulmonary artery; PH, pulmonary hypertension; RPA, right pulmonary artery; and RVOT, right ventricular outflow tract.
