Aortic valve diseases (AVD) require regular monitoring of aortic size and blood speeds. MRI can quantify morphology and flow parameters, such as velocity and wall shear stress, with high accuracy and reproducibility, especially as compared to echocardiography. However, the value proposition may be low for performing repeated MRI if there has been no change in disease state. A quick, inexpensive and easy to use test that identifies potential need for MR imaging could significantly raise the cost-effectiveness of using MRI for monitoring AVD. Here we show high potential screening efficacy of using seismocardiography to select AVD patients needing MRI examination.
