How is the severity of pulmonary valve stenosis determined ?
• Mild: it' the valve area is larger than 1.0 cm2 per square metre, the transvalvular gradient is less than 50 mmHg, or the peak right ventricular systolic pressure is less than 75 mmHg.
• Moderate: if the valve area is 0.5-1.0 cm2 per square metre, the transvalvular gradient is 50-80 mmHg, or the right ventricular systolic pressure is 75-100 mmHg.
• Severe: if the valve area is less than 0.5 cm2 per square metre, the transvalvular gradient is more than 80 mmHg, or the right ventricular systolic pressure is more than 100 mmHg.
