Unlock precise aortic valve area estimations with our Gorlin Formula Calculator. Ideal for cardiologists and medical students, this tool swiftly calculates AVA using cardiac output, heart rate, systolic ejection period, and mean pressure gradient. Understand aortic stenosis severity better with instant, reliable results.
Formula:
Aortic Valve Area (AVA) = Cardiac Output (CO) / (Heart Rate (HR) × Systolic Ejection Period (SEP) × C × √Mean Pressure Gradient (MPG))
- CO: Cardiac Output (mL/min)
- HR: Heart Rate (beats/min)
- SEP: Systolic Ejection Period (seconds)
- C: Constant (typically 44.3 for metric units)
- MPG: Mean Pressure Gradient (mmHg)
