Objective: To optimize the predictive value of cardiac magnetic resonance imaging (MRI) for improvement of myocardial dysfunction prior to percutaneous coronary intervention (PCI). Methods: We performed cardiac MRI in 72 patients (male 87%, age 60 years) before and 6 months after successful PCI (43/72) or unsuccessful PCI (29/72) of a chronic total coronary occlusion (CTO). Before PCI, 5 viability parameters were evaluated: transmural extent of infarction (TEI), contractile reserve during dobutamine, end diastolic wall thickness, unenhanced rim thickness and segmental wall thickening of the unenhanced rim (SWTur). Multivariate analysis was performed and based on the regres Results: The predictive value of a combination of contractile reserve, SWTur and TEI was incremental to TEI alone (AUROC 0.91 vs. 0.77; p < 0.001). A viability score of >= 5 based on contractile reserve (RC = 4), SWTur (RC = 1) and TEI (RC = 2) was 91% sensitive and 84% specific in predicting improvement of myocardial function. Conclusion: Combining viability parameters results in a better prediction of improvement of dysfunctional myocardial segments after a successful PCI. (c) 2011 Elsevier Ireland Ltd.
