Early assessment of infarct size by feature tracking cardiac MRI in patients with myocardial infarction

Feature tracking cardiac magnetic resonance imaging: A review of a novel non-invasive cardiac imaging technique

“…Circumferential strain analysis provided an objective method in the assessment of infarct size[32]. They found similar utility of FTI in another study of 54 patients with first time STEMI[33]. …”

“…Steinmetz et al[ 35 ] studied 26 patients with uncorrected Ebstein’s anomaly and 10 healthy controls with FT to measure right and left ventricular deformation and dyssynchrony which showed RV intraventricular dyssynchrony and reduced RV global strain in patients with Ebstein’s Anomaly as compared to healthy controls. Buss et al[ 33 ] studied 210 patients with dilated cardiomyopathy with FT and noted that LV longitudinal strain assessment via FT was an independent predictor of patient survival and thus a helpful diagnostic tool for risk stratification in this patient population beyond clinical parameter and standard CMR[ 32 ]. Similarly, in hypertrophic cardiomyopathy (HCM) patients, Smith et al[ 36 ] used FT to follow 30 HCM pediatric patients (14.1 ± 3.2 years) and the relationship of LGE (present in 17 of those patients) to adverse clinical outcome (defined as cardiac death non sustained Ventricular tachycardia, ventricular fibrillation and appropriate AICD discharge) over a period of 26.9 mo.…”
