Inspired by commonly used echo calculator sets (e.g. Canadian Society of Echocardiography MDMath). Double-check against your local guideline set.
Calculators
Cardiac Output (LVOT)
Stroke volume, cardiac output, cardiac index, and stroke volume index.
Aortic Valve Area + Dimensionless Index
Continuity equation AVA (VTI) + velocity ratio (VTI/Vmax).
LFLG
Low-Flow Low-Gradient AS Helper
Classify patterns using AVA, mean gradient, SVI, and LVEF.
Mitral Stenosis (MVA)
MVA by pressure half-time and optional continuity equation.
Pulmonary Artery Acceleration Time
PAAT quick interpretation + optional mPAP estimate.
RVSP / PASP from TR
RVSP ≈ 4×TRVmax² + RAP (choose RAP).
Shunt
Qp/Qs (RVOT vs LVOT)
Pulmonary vs systemic flow ratio (shunt quick check).
MR
PISA (Mitral Regurgitation)
PISA flow, EROA, and regurgitant volume.
Modified Bernoulli
ΔP = 4 × v² (quick gradient from velocity).
BSA + BMI
Body surface area (Mosteller) and BMI for indexing.
