Aim. To compare myocardial imaging methods in patients with complicated coronary artery disease with significantly decreased myocardial contractility.Material and methods. This single-center retrospective study included 109 patients with complicated coronary artery disease who underwent surgical treatment between 2014 and 2020. All patients had indications for delayed contrast-enhanced cardiac magnetic resonance imaging (MRI) in order to determine myocardial viability due to a pronounced decrease in left ventricular contractility according to echocardiography (ejection fraction (EF) ≤30%).Results. Impairment of local contractility according to MRI and echocardiography significantly correlates with depth of contrast accumulation (p=0,0000000018 and p=0,0000034, respectively). Delayed contrast-enhanced cardiac MRI with cine sequences allows to determine higher number of impaired contractility cases compared with echocardiography (p=0,000006).Conclusion. MRI with cine sequence allowed to determine higher number of impaired contractility cases compared with echocardiography. Delayed contrastenhanced MRI is a reliably more sensitive method than electrocardiography in detecting left ventricular scarring. The depth of contrast agent accumulation correlates with local contractility impairment detected by echocardiography and delayed contrast-enhanced cardiac MRI.

Deformation Measurements

The aim of this article is to discuss the present and future potential of deformation imaging by echocardiography and scar visualisation by magnetic resonance imaging (MRI) in patients with coronary artery disease (CAD). The two methods are clearly different: one is concerned with function, the other with morphology. Echocardiography, with its versatility of methods and high applicability, will continue to be the workhorse in cardiac imaging of patients with CAD. Important additional information can be extracted from deformation imaging methods, especially due to the high temporal resolution in tissue Doppler. Deformation measurements in 3D images are still limited by their lower resolution compared with 2D but will continue to improve. The standardisation of image analysis and the collaboration within the echocardiographic community to conduct larger studies will be important tasks in the attempt to establish evidence for the new methods. Late enhancement MRI is a method with unique properties and will continue to be an important alternative in selected patients and settings, as well as an invaluable research tool.
