Key result
Velocity-encoded cine MR imaging accurately estimated aortic valve pressure gradients, correlating closely with Doppler echocardiography (r=0.96) and cardiac catheterization (r=0.97).
Why the study?
Does velocity-encoded cine MR imaging accurately estimate pressure gradients across the aortic valve compared to Doppler echocardiography and cardiac catheterization in patients with aortic stenosis?
Observational (n=19)
Does velocity-encoded cine MR imaging accurately estimate pressure gradients across the aortic valve compared to Doppler echocardiography and cardiac catheterization in patients with aortic stenosis?
Effect estimate: r = 0.96 and 0.97
Velocity-encoded cine MR imaging is a feasible and accurate noninvasive method for quantifying pressure gradients in aortic stenosis.

Supports velocity-encoded cine MR for noninvasive aortic stenosis gradient estimation; leaves open prospective outcome validation before clinical adoption.
Eichenberger et al. (1993) conducted an observational in Aortic valve stenosis (n=19). Velocity-encoded cine MR imaging vs. Doppler echocardiography and cardiac catheterization was evaluated on Correlation of pressure gradients with established methods (r = 0.96 and 0.97). Velocity-encoded cine MR imaging accurately estimated aortic valve pressure gradients, correlating closely with Doppler echocardiography (r=0.96) and cardiac catheterization (r=0.97).
