TAPSE

TAPSE: Tricuspid annular plane systolic excursion — simple M-mode measurement of RV systolic function.

RV Assessment

TAPSE Measurement (mm)

M-mode measurement of lateral tricuspid annulus displacement from diastole to systole

Normal Reference Values

>16 mm: Normal

14–16 mm: Mild Dysfunction

11–14 mm: Moderate Dysfunction

<11 mm: Severe Dysfunction

Guidelines & Evidence

Verified

Last Review: 2026-07-17

When to Use

First-line RV systolic function assessment on echocardiography

Screening for RV dysfunction in pulmonary hypertension

Risk stratification post-MI (especially inferior/RV infarction)

Serial monitoring in HF, PH, and after lung transplant

Prognostic indicator in acute decompensated HF

Key Advantages

Simple M-mode measurement; reproducible and operator-independent

No contrast required; works in poor acoustic windows

Correlates with RV EF from cardiac MRI

ESC/ASE endorsed; part of routine echo protocols

How it Works

Measurement Technique

Obtained in apical 4-chamber view (M-mode)

Cursor placed at lateral tricuspid annulus (not at RV free wall)

Measure systolic displacement from annular position in diastole to systole

Measured in mm; independent of image angle

Normal & Abnormal Values

TAPSE (mm)	RV Systolic Function	Prognosis
>16	Normal	Normal RV function
14–16	Mild Dysfunction	Mildly reduced
11–14	Moderate Dysfunction	Moderately reduced
<11	Severe Dysfunction	Severe reduction; high mortality risk
