Using tagged cine magnetic resonance imaging (MRI) to analyze myocardial strain provides direct information regarding the timing of onset and peak of myocardial contraction and allows for the evaluation of regional function and mechanical dyssynchrony. Cardiac MRI lacks the disadvantages of acoustic windows and a narrow field of view, with the advantage of measuring right ventricular strain and the geometric difference in left ventricular contraction. Previous studies using tagged MRI demonstrated that a contraction delay between the right and left ventricles correlated with right ventricular dysfunction in adults with congenital heart disease and pulmonary hypertension, and that spatial dyssynchrony was associated with a reduction in cardiac sympathetic activity in non-ischemic heart failure. Recently, cardiac computed tomography (CT) was also found to enable the quantitative assessment of two-dimensional and three-dimensional myocardial strain. This review focuses on strain analysis using tagged MRI and its current post-processing methods, known as feature tracking, discusses upcoming CT-based methods of strain analysis, and introduces their clinical applications.

“…CTA-derived assessment of strain has emerged as a valuable method for the assessment of cardiac function, and it shows close correlations with both echocardiography and CMR [10][11][12][13]. The usefulness of CT-derived assessments of left ventricular strain in severe aortic stenosis [11], aortic valve stenosis [14], adult congenital heart disease [15] and myocardial infarction [16] has been reported. However, to the best of our knowledge, there have been no studies on CAD.…”

Background Computed Tomography feature tracking (CT-FT) has emerged as a valuable method for the assessment of cardiac function. However, there have been no study about the usefulness of CT-derived assessments of left ventricular strain on coronary artery disease (CAD). Our aim was to evaluate the regional left ventricular (LV) systolic deformation in patients with left anterior descending coronary (LAD) stenosis using CT-FT. Methods Seventy-six patients with LAD stenosis were enrolled. The patients were divided into four groups according to the percentage of LAD stenosis: ≤25% was defined as group I (24 patients), 26–49% as group II (17 patients), 50–74% as group III (21 patients), and ≥ 75% as group IV (14 patients).Thirty-two sex- and age-matched normal subjects were included as controls. Results No intergroup differences were found between groups I-IV and the controls in terms of the left ventricular ejection fraction, end-diastolic volume and end-systolic volume. However, the longitudinal strain (LS) of the LAD territory was significantly reduced in groups I-IV compared with the controls (-20.8% and − 18.5% and − 18.6% and − 17.0% vs -23.7%, respectively). The circumferential strain (CS) of the LAD territory was significantly reduced in groups III and IV compared with the controls and groups I and II (-22.4% and − 22.2% vs -25.4% and − 24.1% and − 25.3%, respectively). Compared with non-LAD territory, groups II-IV had significantly increased LS (-19.9% vs -21%; -18.6% vs -21.9%; -16.4% vs -20.1%). The severity of LAD stenosis had a positive correlation with the LS of the LAD territory (r = 0.438, p = 0.002). Conclusion CT‑FT can detect decreasing LV systolic function in patients with LAD stenosis. With the increasing severity of LAD stenosis, the LV regional systolic deformation of the LAD territory was reduced.

Background: Computed tomography feature tracking (CT-FT) has emerged as a valuable method for the assessment of cardiac function. However, no studies have investigated the usefulness of CT-derived assessments of left ventricular (LV) strain in coronary artery disease (CAD). Our aim was to evaluate regional LV systolic deformation in patients with left anterior descending coronary artery (LAD) stenosis using CT-FT.Methods: Seventy-six patients with LAD stenosis were enrolled. The patients were divided into four groups according to the percentage of LAD stenosis: ≤25% was defined as group I (24 patients), 26% to 49% as group II (17 patients), 50% to 74% as group III (21 patients), and ≥75% as group IV (14 patients). Thirty-two sex- and age-matched healthy subjects were included as controls.Results: No intergroup differences were found between groups I-IV and the controls in terms of the left ventricular ejection fraction, end-diastolic volume and end-systolic volume. However, the longitudinal strain (LS) of the LAD territory was significantly reduced in groups I-IV compared with the controls (-20.8%, -18.6%, -18.6%, and -17.0% vs -23.7%, respectively). The circumferential strain (CS) of the LAD territory was significantly reduced in groups III and IV compared with the controls and groups I and II (-22.4% and -22.1% vs -25.4%, -24.1%, and -25.3%, respectively). Compared with the non-LAD territory, the LAD territory in groups II-IV showed significantly increased LS (-18.6% vs -21.9%, p=0.07; -18.6% vs -21.9%, p=0.024; -17.5% vs -20%, p=0.032, respectively). The severity of LAD stenosis was positively correlated with the LS of the LAD territory (r = 0.438, p=0.002).Conclusion: CT‑FT can detect decreasing LV systolic function in patients with LAD stenosis. LV regional systolic deformation of the LAD territory was reduced with increasing LAD stenosis severity.
