The gold standard measurement of RV–pulmonary arterial (PA) coupling is the ratio of end-systolic to arterial elastances (Ees/Ea) which is optimal for RV flow output at minimal energy cost at values between 1.5 and 2 [2]. Progressive RV–PA uncoupling is associated with maintained RV dimensions down to Ees/Ea values of around 0.8 [3]. Thus, the evaluation of RV–PA coupling would theoretically allow monitoring of the transition from compensated to decompensated RV function in pulmonary hypertension. However, measuring RV–PA coupling at the bedside is technically demanding and invasive.The ratio of tricuspid annular plane systolic excursion to systolic pulmonary artery pressure is a simple echocardiographic parameter that reflects haemodynamic severity and predicts survival in pulmonary hypertension due to lung diseases. http://bit.ly/2KgLAbREditorial assistance was provided by Claire Mulligan (Beacon Medical Communications Ltd, Brighton, UK), funded by the University of Giessen.
