A hybrid approach for quantification of aortic valve stenosis using cardiac magnetic resonance imaging and echocardiography.

Background: Doppler-derived calculation of aortic valve area (AVA) using the continuity equation can be difficult at times, e.g. due to poor acoustic windows, heavy calcification of the aortic valve, or significant flow acceleration in the left ventricular outflow tract.

Effect of endocardial trabeculae on left ventricular measurements and measurement reproducibility at cardiovascular MR imaging.

Purpose: To prospectively assess the effect of including or excluding endocardial trabeculae in left ventricular (LV) measurements and the reproducibility of these measurements at cine cardiovascular magnetic resonance (MR) imaging with true fast imaging with steady-state precession (FISP).

Materials And Methods: The study was approved by the local ethics committee, and each subject gave informed consent before participating. Twenty healthy subjects and 20 consecutive patients underwent 1.
