Enter weight & height in Tab 1 for BSA-based Z-scores. All measurements in mm. Taken at end-diastole, leading edge to leading edge (ASE convention).
| Parameter | Measured (mm) | Normal Range | Z-Score | Interpretation |
|---|
M-mode cursor through the LV at the level of the mitral valve chordae in parasternal long axis. Values used for EF/FS calculation if biplane Simpson not available.
Biplane Simpson preferred per ASE 2015. Use both apical 4-chamber and 2-chamber views.
PW Doppler sample volume at mitral leaflet tips (transmitral) and just below aortic valve (LVOT). Record at rest during quiet respiration.
Enter LVOT Diameter and VTI in the Spectral Doppler tab — CO auto-calculates here.
TAPSE and S' are primary RV systolic markers in pediatric echo. Enter all available parameters.
Grading uses E, E/A, average E/e', TR velocity, and LA volume. Enter all available parameters for accurate classification.
Sample volume 5–10mm at each annular site. Optimise frame rate ≥200 fps. Filter set low. Measure three cycles and average.
Speckle-tracking echocardiography. Enter GLS as a negative value (e.g. −18%). More negative = better function. Normal LV GLS ≤ −20%.
Measure in end-diastole at the point of maximum width in each standard view. Circumferential vs loculated should be noted.
Measure IVC 1–2 cm from cavoatrial junction. Collapsibility assessed with sniff test during quiet respiration.
Enter Doppler values. Severity auto-calculated per standard echocardiographic criteria.
Score each criterion. Auto-classifies as Definite / Probable / Borderline / Normal RHD.

| Z-Score | Classification | Recommended Action |
|---|---|---|
| Z < 2 | Normal | Routine follow-up |
| Z 2–2.49 | Borderline dilatation | Repeat echo in 1–2 weeks |
| Z 2.5–4.9 | Small aneurysm | Aspirin + close follow-up; cardiology referral |
| Z 5–9.9 | Medium aneurysm | Antiplatelet + anticoagulation; urgent cardiology |
| Z ≥ 10 | Giant aneurysm | High-risk management; cath / surgery evaluation |
