Expanding role of cardiovascular magnetic resonance in left and right ventricular diastolic function.
This article focuses on the role of cardiovascular magnetic resonance (CMR) in understanding the physiology of diastolic function and on the future applications of CMR as they relate to diastolic function evaluation. CMR has a demonstrated potential to define diastolic function and quantify its properties, in terms of active and passive stages, and its relaxation and compliance characteristics. CMR is also useful for assessing inflow and myocardial velocities, and untwisting properties of the chamber and myocardium, thus providing insights not fully available in other invasive and noninvasive strategies. CMR, which offers the necessary capabilities to evaluate the complex structure of the right ventricle, can serve in the future as the standard for evaluating diastolic function as it currently does for systolic function.
