This has prompted the use of the less invasive hepatic venous pressure gradient (HVPG), widely accepted as the PPG equivalent.1–3 In a recent article in Gut, HVPG was used as the only criterion to assess haemodynamic response (reduction in HVPG of ≥20% or to values <12 mm Hg) rates to carvedilol in propranolol non-responders.1 Although accurate, HVPG is still invasive, and thus not routinely performed in all centres.2 ,3 As HVPG becomes standard practice, repeated invasive measurement has stimulated the search for non-invasive techniques to measure PPG.3–5 Here, we present a virtual PPG (vPPG) based on CT angiography and Doppler ultrasound.The VIRGIN Study was a multicentre, blinded, prospective, analytical trial carried out at Tongji Hospital, Shanghai and 302 Hospital, Beijing. The study was … ER -
