Left ventricular circumferential strain and coronary microvascular dysfunction: A report from the Women's Ischemia Syndrome Evaluation Coronary Vascular Dysfunction (WISE-CVD) Project

Comparison of Diagnostic Value Between STE+LDDSE and CMR-FT for Evaluating Coronary Microvascular Obstruction in Post-PCI Patients for STEMI

“…A study by Tamarappoo et al showed that CS of LV could predict CMVO. 34 This is consistent with our findings. Both CMR-FT and LGE-CMR have the advantages of high spatial resolution and no-radiation, but contrast agent injection is essential for LGE, compared to CMR-FT, this renders CMR-FT to be more applicable in clinic.…”

Ultra-high sensitivity cardiac troponin-I concentration and left ventricular structure and function in women with ischemia and no obstructive coronary artery disease

“…Myocardial feature tracking of cine images was performed using dedicated software (Circle CVI 42 version 5.3.0, Calgary, AB, Canada) to assess LV systolic and diastolic function, as previously described [ 10 , 26 ]. Briefly, a single experienced observer manually traced the LV endocardial and epicardial borders at end-diastole from short-axis images spanning the LV from base-to-apex, and horizontal and vertical long axis images).…”

“…Briefly, a single experienced observer manually traced the LV endocardial and epicardial borders at end-diastole from short-axis images spanning the LV from base-to-apex, and horizontal and vertical long axis images). Previously published normal strain values using the same technique, analysis software version, and imaging core laboratory include: longitudinal systolic strain rate (SR) −1.00 ± 0.21, early longitudinal diastolic SR 1.13 ± 0.32, late longitudinal diastolic SR 0.69 ± 0.26, circumferential systolic SR −1.08 ± 0.20, early circumferential diastolic SR 1.38 ± 0.37, late circumferential diastolic SR 0.56 ± 0.21 [ 26 ]. Intra-observer reliability in corelab for measuring early circumferential diastolic SR, early radial diastolic SR, early longitudinal diastolic SR reported as a coefficient of variation, was 7.6%, 7.3%, and 11.4%, respectively.…”

ATTR Amyloidosis: Current and Emerging Management Strategies

“…However, their utility in diagnosing subclinical ATTR-CA has not been systematically studied. Whether ventricular or atrial strain and strain rates measured from cine CMR images using feature tracking software are helpful or not is unknown ( 72 , 73 ).…”
