Abstract

Background

The presence of myocardial fibrosis is associated with adverse outcome in dilated cardiomyopathy (DCM). Delayed contrast-enhanced cardiac magnetic resonance (DE-CMR) currently represents the gold standard in noninvasive evaluation of myocardial scarring. However, a significant number of patients are unable to undergo DE-CMR study for various reasons. We sought to determine the diagnostic accuracy of cardiac CT (CCT) compared with CMR in the investigation of the presence of delayed contrast enhancement (DCE) in subjects with DCM.

Methods

We prospectively enrolled 17 consecutive patients with DCM, who were initially referred to our institution because of recently manifested heart failure due to unexplained left ventricular systolic dysfunction. In all subjects, CCT and DE-CMR were performed within 1 week.

Results

CCT and DE-CMR showed satisfactory agreement in detecting DCE (agreement in 82% cases, κ = 0.56) with 50% sensitivity, 100% specificity, and a positive predictive value of 100%.

Conclusion

CCT may be a valuable method for detecting DCE in patients with DCM. CCT thus might be considered as an alternative method to DE-CMR in the assessment of the presence and extent of myocardial fibrosis in subjects who are not suitable for DE-CMR examination.
