Calculation Method
Gorlin Formula:
Valve Area = Cardiac Output / (Heart Rate × Systolic Ejection Time × 44.3 × √Mean Gradient)
Where:
• Cardiac Output = 0 L/min
• Heart Rate = 0 beats/min
• Systolic Ejection Time = 0 seconds
• Mean Gradient = 0 mmHg
• 44.3 = Empirical constant

Gorlin Formula Information
Aortic Valve: Normal >2.0 cm², Mild 1.5-2.0 cm², Moderate 1.0-1.5 cm², Severe <1.0 cm²
Mitral Valve: Normal 4.0-6.0 cm², Mild 1.5-2.5 cm², Moderate 1.0-1.5 cm², Severe <1.0 cm²
Note: The Gorlin formula is used to calculate effective valve area during cardiac catheterization. Results should be interpreted in clinical context.
