Summary of haemodynamic assessments

	Technique	View	Cursor position	Comment
Ventricular function
RV fractional area change	2‐D	Apical four chamber	Include full view of the right ventricle (base to apex)	[(RV four‐chamber area at end‐diastole – RV four‐chamber area at end‐systole)/RV four‐chamber area at end‐diastole] × 100%
Tricuspid annular peak systolic excursion	M‐mode	Apical four chamber	Tricuspid annulus	Measure of longitudinal contractility
Tricuspid MPI	TDI	Apical four chamber	Tricuspid lateral annulus	(IVCT + IVRT)/RVET
Pulmonary vascular dynamics
TPV/RVETc	PWD	Long axis RVOT	Aligned with the flow, sample at tips of pulmonary leaflets	1/(TPV/RVETc) acts as a surrogate for pulmonary resistance
RPA inferior wall thickness in diastole	CCM TDI	Short axis	Perpendicular to RPA	Measured in end diastole
RPA pulsatile diameter	CMM TDI	Short axis	Perpendicular to RPA	Difference between the RPA internal calibre in diastole and systole

PWD, pulse wave Doppler; CMM, colour m‐mode; TPV, time to peak velocity; RVET, right ventricular ejection time; TAPSE, tricuspid annular peak systolic excursion; RV, right ventricular; 2‐D, two dimensional; RVOT, right ventricular outflow tract; TDI, tissue Doppler imaging; IVCT, isovolumic contraction time; IVRT, isovolumic relaxation time.
