Cardiac MRI provides incremental utility over conventional techniques for assessing myocardial viability, predicting left ventricular functional recovery, and determining long-term prognosis.
Does cardiac magnetic resonance provide incremental utility for assessing viability and predicting prognosis in patients undergoing cardiac surgery?
Cardiac MRI offers powerful predictive utility for left ventricular functional recovery and long-term prognosis in patients undergoing cardiac surgery.
This dialog between a cardiac surgeon (C.L.) and cardiac imager (J.W.W.) provides an overview of cardiac MRI (CMR) methods relevant to cardiac surgery. Major areas of focus include logistics of performing a CMR exam, as well as established and emerging methods for assessment of cardiac structure, function, valvular performance, and tissue characterization. Regarding tissue characterization, a major area of focus concerns CMR assessment of viability, for which this modality has been shown to provide incremental utility to conventional techniques for detection of presence and transmural extent of infarction, as well as powerful predictive utility of recovery of left ventricular systolic function as well as long term clinical prognosis in patients with an array of clinical conditions, including coronary artery disease and valvular heart disease both before and following cardiac surgery.
Kagan et al. (Wed,) conducted a review in Cardiac surgery. Cardiac MRI (CMR) vs. Conventional techniques was evaluated. Cardiac MRI provides incremental utility over conventional techniques for assessing myocardial viability, predicting left ventricular functional recovery, and determining long-term prognosis.
