Aortic Stenosis Grading on echocardiography The cut-offs for grading can be found in table 1. Discrepancies are common and are usually caused by: - incorrect measurements - high or low flow - extremes of body size. In addition, there is evidence that in European populations the cut-off maximum velocity (V max) of 4.0 m/s and mean gradient 40 mmHg coincide better with an EOA of 0.8 cm2 rather than 1.0 cm2. #Diagnosis #Cardiology #Aortic #Stenosis #AorticStenosis #Classification #Severity #Criteria #MeanGradient #AorticValveArea
