Relationship of TAPSE, TRV and TAPSE/TRV ratio in 1077 patients. As can be seen, some patients had a TAPSE < 17mm and low TRV, or TAPSE > 17mm and a high TRV, giving higher, pseudo-normalised TAPSE/TRV ratios. Fewer patients had TAPSE ≥ 17 mm and TRV ≤ 2.8 m/s. A TRV of > 2.8 m/s is used as a cut off to increase probability of pulmonary hypertension [34]
