We appreciated the paper by Dahiya et al. attempting to improve non- invasive estimation of pulmonary vascular resistance (PVR)(1). However, some points deserve few comments. 1. The new formula (PVRc) compared to the previous one by Abbas et al.(2) (PVRe) includes E/e' ratio, in order to take into account pulmonary capillary wedge pressure (PCWP) and better estimate transpulmonary gradient. E/e' is a ratio, but needs to...
