exercise stress echocardiography and tissue synchronization imaging of myocardial dyssynchrony
conclusions the tsi analysis in patients with cad may be considered an interesting parameter in addition to the conventional echocardiographic parameters during ese. background stress echocardiography represents one of the best possible imaging choice for the diagnosis and stratification of patients with coronary artery disease (cad). however, this imaging technique presents some limitations su...
متن کاملAssessment of hemodialysis effect on left ventricular mechanical dyssynchrony by tissue synchronization imaging
Background: Abnormal myocardial loading can contribute to left ventricular (LV) mechanical dyssynchrony in patients with end-stage renal disease (ESRD) and may be a factor contributing to the high incidence of cardiac deaths in these patients. The study aims to evaluate the possible presence of LV dyssynchrony in ESRD patients, and acute effect of hemodialysis (HD) on LV synchronicity using tis...
متن کاملMechanical dyssynchrony in dilated cardiomyopathy with intraventricular conduction delay as depicted by 3D tagged magnetic resonance imaging.
Recent studies have generated interest in the potential for left or biventricular pacing to improve cardiac function in patients with dilated cardiomyopathy and intraventricular conduction delays.1–4 The premise is that these hearts display profound basal mechanical dyssynchrony and that pacing can restore synchronization and, thereby, improve function. Here, we demonstrate the extent of mechan...
متن کاملValue of mechanical dyssynchrony as assessed by radionuclide ventriculography to predict the cardiac resynchronization therapy response.
AIMS To assess the value of mechanical dyssynchrony measured by equilibrium radionuclide angiography (ERNA) in predicting long-term outcome in cardiac resynchronization therapy (CRT) patients. METHODS AND RESULTS We reviewed 146 ERNA studies performed in heart failure patients between 2001 and 2011 at our institution. Long-term follow-up focused on death from any cause or heart transplantatio...
متن کاملIntraventricular dyssynchrony predicts mortality and morbidity after cardiac resynchronization therapy: a study using cardiovascular magnetic resonance tissue synchronization imaging.
OBJECTIVES We aimed to assess a novel measure of left ventricular (LV) dyssynchrony, a cardiovascular magnetic resonance-tissue synchronization index (CMR-TSI), in patients with heart failure (HF). A further aim was to determine whether CMR-TSI predicts mortality and major cardiovascular events (MCE) after cardiac resynchronization therapy (CRT). BACKGROUND Cardiac dyssynchrony is a predictor...
