IVCCI method validly estimates PASP yet offers no improvement over constant 10 mm Hg; leaves open its role in specific clinical scenarios.
Does estimating right atrial pressure via the inferior vena cava collapsibility index improve the accuracy of Doppler-derived pulmonary artery systolic pressure compared to traditional formulas?
Using the inferior vena cava collapsibility index to estimate right atrial pressure for Doppler-derived pulmonary artery systolic pressure is valid but does not improve accuracy over simply assuming a constant 10 mm Hg right atrial pressure.
