RT3D may improve aortic valve area accuracy over 2D/Doppler methods; hypothesis-generating and requires prospective validation before clinical adoption.
Does real-time three-dimensional (RT3D) echocardiography improve the accuracy of aortic area calculation compared to standard methods in patients with aortic stenosis?
Real-time 3D echocardiography provides a more accurate calculation of aortic valve area and grading of aortic stenosis severity than standard 2D and Doppler methods when compared to the invasive Gorlin's equation.
