TAPSE for RV Systolic Function

Tricuspid Annular Plane Systolic Excursion (TAPSE). Simple M-mode echocardiographic measure of RV longitudinal systolic function. Normal TAPSE ≥17 mm. Reduced TAPSE correlates with worse outcomes in PAH and right heart failure.

Score interpretation

Normal RV Function

→ TAPSE ≥17 mm: Normal RV longitudinal systolic function. No evidence of RV dysfunction by TAPSE criterion. Reassess if RV FAC <35% or clinical RV failure signs present (raised JVP, peripheral oedema, hepatomegaly).

Mildly Reduced RV Function

→ TAPSE 12–16 mm: Mildly reduced RV function. Investigate underlying cause (PAH, LHD, CTEPH, PE). Monitor serially; optimise fluid balance; treat cause. RHC if PAH suspected.

Significantly Reduced RV Function

→ TAPSE <12 mm: Significantly reduced RV systolic function. High-risk marker in PAH, LVAD, post-cardiac surgery, and acute PE. Urgent cardiology/PH review; RHC; diuresis; consider pulmonary vasodilators; RVAD if refractory RV failure.

Interpretation bands for the TAPSE. Apply clinical judgement and local guidance.
