In particular, the 6-mm group compared to the 8-mm group showed a trend, although not statistically significant, toward a greater increase in both CO (+1.22 [0.13-2.56] L/min vs 0.76 [0.00-1.20] L/min, P = .09) and stroke volume index (8.22 [4.18, 23.60] mL/min/m 2 vs 5.57 [1.52-12.70] mL/min/m 2 , P = .06), in tandem with a greater reduction in PVR (–5.91 [9.32, 2.77] WU vs –2.62 [5.14, 0.93] WU, P = .03).
