Echocardiographic quantification of left ventricular asynchrony predicts an acute hemodynamic benefit of cardiac resynchronization therapy.
OBJECTIVES We sought to determine whether radial left ventricular (LV) asynchrony in patients with heart failure predicts systolic function improvement with cardiac resynchronization therapy (CRT). BACKGROUND We quantified LV wall motion by echocardiography to correlate the effects of CRT on LV systolic function with wall motion synchrony. METHODS Thirty-four patients underwent echocardiogr...

OBJECTIVES The value of interventricular and intraventricular echocardiographic asynchrony parameters in predicting reverse remodeling after cardiac resynchronization therapy (CRT) was investigated. BACKGROUND Cardiac resynchronization therapy has been suggested as a promising strategy in patients with severe heart failure and left bundle branch block (LBBB), but the entity of benefit is vari...

متن کاملTechniques for identification of left ventricular asynchrony for cardiac resynchronization therapy in heart failure
The most recent treatment option of medically refractory heart failure includes cardiac resynchronization therapy (CRT) by biventricular pacing in selected patients in NYHA functional class III or IV heart failure. The widely used marker to indicate left ventricular (LV) asynchrony has been the surface ECG, but seems not to be a sufficient marker of the mechanical events within the LV and predi...
متن کاملLeft ventricular resynchronization is mandatory for response to cardiac resynchronization therapy: analysis in patients with echocardiographic evidence of left ventricular dyssynchrony at baseline.
BACKGROUND Recent studies have demonstrated that a positive response to cardiac resynchronization therapy (CRT) is related to the presence of preimplantation left ventricular (LV) dyssynchrony. The time course and the extent of LV resynchronization after CRT implantation and their relationship to response are currently unknown. METHODS AND RESULTS One hundred consecutive patients scheduled fo...
