CMR feature tracking in Kawasaki Disease convalescence
نویسندگان
چکیده
Background Myocardial inflammation has been described as a global finding in the acute phase of Kawasaki Disease. Despite normal LV systolic function by routine functional measurements, reduced longitudinal strain (S) and strain rate (SR) have been detected by echocardiography in the acute phase, which may potentially predict late onset heart failure. We aimed to determine whether left ventricular (LV) myocardial deformation indices can detect subclinical myocardial abnormalities in Kawasaki Disease (KD) convalescence. We hypothesized that subclinical myocardial abnormalities due to inflammation represent an early manifestation of the disease that persist in convalescence.

BACKGROUND Kawasaki disease is an acute, systemic vasculitis that affects the coronary arteries. However, the relationship between myocardial fibrosis and Kawasaki disease has been completely unknown until now. We aimed to provide quantitative information about myocardial fibrosis using cardiac integrated backscatter in Han race Kawasaki disease patients. METHODS Ninety Kawasaki disease patie...
متن کاملEvaluation of left atrial myocardial deformation in patients with acute MR after STEMI using CMR feature tracking
Background Left atrium (LA) is an important predictor of cardiovascular morbidity and mortality. Data related to LA functional changes during acute MR after ST-segment elevation myocardial infarction (STEMI) are limited. CMR is rapidly evolving imaging modality and feature tracking becomes very promising technique for assessment of myocardial deformation. The aim of this study was to investigat...
متن کاملFunctional left atrial CMR parameters are early predictors of left atrial alterations in hypertension and strongly associated with lv remodeling
Background Left atrial (LA) structural and functional changes are determinant steps on the pathway toward heart failure with preserved ejection fraction in hypertensive (HT) patients. Most LA studies are based on LA volumes evaluation in CMR and echocardiography or on echocardiographic speckle tracking estimation. Since LA functional evaluation by CMR is now emerging we aimed at 1) evaluating L...
متن کاملIntraindividual comparison of circumferential strain using speckle tracking by echocardiography versus CMR feature tracking and myocardial tagging in patients
Background Left ventricular myocardial motion analysis and the assessment of regional dysfunction are crucial for the detection and prognosis in different cardiac pathologies. Myocardial tagging (MT) is a cardiac magnetic resonance (CMR) based method for tracking myocardial motion, which has been established as reference standard for assessment of strain. Currently, strain can also be assessed ...
