Cardiac Mechanics Evaluated by Speckle Tracking Echocardiography
Natural myocardial markers, or speckles, originated from constructive and destructive interference of ultrasound in the tissues may provide early diagnosis of myocardial changes and be used in the prediction of some cardiac events. Due to its relatively temporal stability, speckles can be tracked by dedicated software along the cardiac cycle, enabling the analysis of the systolic and diastolic ...
متن کاملSpeckle‐Tracking Echocardiography in Dogs With Patent Ductus Arteriosus: Effect of Percutaneous Closure on Cardiac Mechanics
BACKGROUND Patent ductus arteriosus (PDA) is 1 of the most common congenital heart defects in dogs and percutaneous closure is effective in achieving ductal closure; PDA closure is associated with abrupt hemodynamic changes. HYPOTHESIS A marked decrease in standard parameters of systolic function as assessed by M- or B-mode echocardiography after PDA closure was identified in previous studies...
متن کاملClinical utility of speckle-tracking echocardiography in cardiac resynchronisation therapy
Cardiac resynchronisation therapy (CRT) can profoundly improve outcome in selected patients with heart failure; however, response is difficult to predict and can be absent in up to one in three patients. There has been a substantial amount of interest in the echocardiographic assessment of left ventricular dyssynchrony, with the ultimate aim of reliably identifying patients who will respond to ...
متن کاملSpeckle tracking echocardiography: clinical applications in cardiac resynchronization therapy.
Cardiac resynchronization therapy (CRT) is a proven therapy for selected patients with heart failure, it has been shown to improve symptoms and left ventricular (LV) function and prolong survival. Despite proven benefit of CRT, a significant proportion of patients fail to respond to CRT. Multiple factors contribute to the non-response such as patient selection and device implantation including ...
متن کاملDyssynchrony by speckle-tracking echocardiography and response to cardiac resynchronization therapy: results of the Speckle Tracking and Resynchronization (STAR) study
AIMS The Speckle Tracking and Resynchronization (STAR) study used a prospective multi-centre design to test the hypothesis that speckle-tracking echocardiography can predict response to cardiac resynchronization therapy (CRT). METHODS AND RESULTS We studied 132 consecutive CRT patients with class III and IV heart failure, ejection fraction (EF) < or =35%, and QRS > or =120 ms from three inter...
