ERO Calculator
To calculate ERO (Effective Regurgitant Orifice), divide the volumetric flow rate by the velocity of the mitral valve. This essential calculation aids in diagnosing and managing valve-related conditions such as mitral regurgitation.
The ERO Calculator simplifies the process of evaluating mitral regurgitation severity by accurately estimating the size of the regurgitant orifice. It is an invaluable tool for cardiologists and echocardiographers, offering precise results to guide clinical decision-making in diagnosing and managing valve diseases.

| Effective Regurgitant Orifice (cm²) | |
| Volumetric Flow Rate (mL/s) | |
| Mitral Valve Velocity (cm/s) |
What is the ERO Calculator?
The ERO Calculator is a specialized tool used to estimate the effective regurgitant orifice area in conditions like mitral regurgitation.
By inputting the volumetric flow rate and the velocity of the mitral valve, healthcare professionals can assess the severity of regurgitation and plan appropriate treatment strategies.
For example, a patient with a volumetric flow rate of 200 mL/s and a mitral valve velocity of 50 cm/s would have an ERO of:
This calculation is critical in clinical settings for assessing valve dysfunction severity, particularly when combined with other diagnostic parameters like regurgitant fraction or vena contracta width. It is commonly applied in echocardiography and valve disease management.
Final Words:
In summary, the ERO Calculator is an essential diagnostic tool for cardiologists, enabling precise assessment of mitral regurgitation severity. By providing quick and accurate results, it plays a pivotal role in ensuring effective patient care and treatment planning.
