Valvular Cardiomyopathy: The Value of Cardiovascular Magnetic Resonance Imaging

Figure 2

A case of aortic stenosis assessment using four-dimensional flow CMR. (a, b) Cine views demonstrating thickened and restrictive opening of aortic valve leaflets with flow acceleration in the aortic root. (c) Increased wall sheer stress on the anterior wall of the aortic sinus and ascending aorta due to eccentric jet through the stenosed valve. (d, e) Cine views with velocity overlay demonstrating flow acceleration greater than 4 m/sec and a two-dimensional plane through that to quantify peak velocity. (f) Peak velocity was consistent with severe aortic stenosis in this case.
