Opinion statement

Echocardiography remains the cornerstone of noninvasive valvular heart disease evaluation. There are instances where MRI can be of use. Aside from the obvious advantage where limited acoustic windows are present, cardiac magnetic resonance (CMR) allows for imaging in any desired plane, and advantage can be taken of the ability to align with any regurgitant or stenotic flow jet. The high spatial resolution and contrast allow for accurate detail of valvular anatomy, but it must be remembered that the images represent a composite of eight to 12 heart cycles. For visualizing multiple valvular abnormalities simultaneously, cardiac MRI has a distinct advantage. Finally, a CMR valvular examination can be combined with accurate assessments of left and right ventricular function, myocardial stress perfusion imaging, and detailed viability determinations in a single examination. This provides a comprehensive presurgical evaluation of cardiac physiology.
