This study supports the concept of an opening reserve of the Avalus valve to explain the PPM conundrum and promotes the use of exercise Doppler-echocardiography to complete the assessment of mismatch, especially in patients with a low-flow state. Published estimated EOA seems reliable to predict the haemodynamic performance of the Avalus valve, whether the flow conditions at rest.
