Feature tracking derived longitudinal and circumferential myocardial strain abnormalities in clinical myocarditis
نویسندگان
چکیده
Background Cardiac magnetic resonance imaging (CMR) is frequently used to assess myocardial involvement to confirm diagnosis of myocarditis. CMR techniques employ T2weighted, early and late gadolinium enhancement (LGE), with two positive sequences widely considered diagnostic for myocardial inflammation. However, these techniques are qualitative and subjective, thus prone to interpretation error. Feature tracking (FT) allows quantitative segmental myocardial strain analysis using traditional cine CMR images. Our hypothesis was that left ventricular (LV) segmental strain would be a more sensitive indicator for myocardial involvement in patients with clinical myocarditis. Regional strain was compared to presence of LGE as a measure of myocardial involvement.

Evaluation of strain and strain rate parameters using two-dimensional speckle-tracking echocardiography in patients with coronary artery disease (Research Article)
The study aimed was to measure left ventricular (LV) strain using speckle tracking echocardiography (STE) for assessment of LV function. Eighty-two subjects (mean age 57±9 years) with suspected chest pain underwent two-dimensional (2D)-echocardiography before coronary angiography. Conventional echocardiographic parameters were used for the assessment of LV function. Longitudinal strain and its ...

BACKGROUND Assessment of left (LV) ventricular function is one of the most important tasks of cardiovascular magnetic resonance (CMR). Impairment of LV deformation is a strong predictor of cardiovascular outcome in various cardiac diseases like ischemic heart disease or cardiomyopathies. The aim of the study was to provide reference values for myocardial deformation derived from the CMR feature...

OBJECTIVE The objective of this study was to determine whether left ventricular (LV) myocardial deformation indices can detect subclinical abnormalities in Kawasaki disease convalescence. We hypothesized that subclinical myocardial abnormalities due to inflammation represent an early manifestation of the disease that persists in convalescence. BACKGROUND Myocardial inflammation has been descr...

UNLABELLED SummaryWe present the case of a 26-year-old male with acute tonsillitis who was referred for coronary angiography because of chest pain, elevated cardiac biomarkers, and biphasic T waves. The patient had no cardiovascular risk factors. Echocardiography showed no wall motion abnormalities and no pericardial effusion. 2D speckle tracking revealed distinct decreased regional peak longit...
متن کاملFeature Tracking in Cardiac Magnetic Resonance Imaging
Purpose: An accurate and practical method to measure parameters like strain in myocardial tissue is of great clinical value, since it has been shown that strain is a more sensitive and earlier marker for contractile dysfunction than ejection fraction (EF). Current CMR technologies for strain assessment are time consuming and difficult to implement in daily clinical practice. Feature tracking is...
