PI, pulsatility index; dpLT, maximum instantaneous pressure difference (lateral tunnel (LT) − corresponding pulmonary artery (PAc)) − minimum instantaneous pressure difference (LT − PAc); dpSVC, maximum instantaneous pressure difference (superior vena cava (SVC) − PAc) − minimum instantaneous pressure difference (SVC − PAc ); FS, fractional shortening; LPA, left pulmonary artery; RPA, right pulmonary artery.
