Atrial Strain and Strain Rate: A Novel Method for the Evaluation of Atrial Stunning
BACKGROUND Atrial fibrillation (AF) is the most common arrhythmia seen in adults. Atrial stunning is defined as the temporary mechanical dysfunction of the atrial appendage developing after AF has returned to sinus rhythm (SR). OBJECTIVES We aimed to evaluate atrial contractile functions by strain and strain rate in patients with AF, following pharmacological and electrical cardioversion and ...
متن کاملCircumferential 2D-strain imaging for the prediction of long term response to cardiac resynchronization therapy
BACKGROUND Cardiac Resynchronization Therapy (CRT) leads to hemodynamic and clinical improvement in heart failure patients. The established methods to evaluate myocardial asynchrony analyze longitudinal and radial myocardial function. This study evaluates the new method of circumferential 2D-strain imaging in the prediction of the long-term response to CRT. METHODS AND RESULTS 38 heart failur...
متن کاملevaluation of left atrial two-dimensional strain in patients with systolic heart failure using velocity vector imaging
background two-dimensional (2d) strain is a new reproducible technique for assessing regional myocardial function; however, its application for evaluation of left atrium (la) function is less studied. objectives we sought to assess la function in heart failure patients using velocity vector imaging (vvi). patients and methods thirty five patients (mean age: 43.34 ± 18.1 years, 59.3% male) with ...

evaluation of longitudinal right ventricular mechanical dyssynchrony before and early after cardiac resynchronization therapy: a strain imaging study
background: the right ventricular (rv) dyssynchrony has not been studied extensively and the existing literature has established the effect of cardiac resynchronization therapy (crt) on the left ventricular (lv) dyssynchrony, but there is a dearth of data on the effect of crt on the forgotten ventricle . we sought to evaluate the presence of mechanical right ventricular dyssynchrony in patients...
