BACKGROUND Data from single-center studies suggest that echocardiographic parameters of mechanical dyssynchrony may improve patient selection for cardiac resynchronization therapy (CRT). In a prospective, multicenter setting, the Predictors of Response to CRT (PROSPECT) study tested the performance of these parameters to predict CRT response. METHODS AND(More)
OBJECTIVES We sought to determine the effects of cardiac resynchronization therapy (CRT) in New York Heart Association (NYHA) functional class II heart failure (HF) and NYHA functional class I (American College of Cardiology/American Heart Association stage C) patients with previous HF symptoms. BACKGROUND Cardiac resynchronization therapy improves left(More)
The prognostic value of ultrasound evaluation of right ventricular (RV) performance in patients with congestive heart failure (CHF) is still a matter of investigation. We studied 140 consecutive patients with chronic CHF and a left ventricular ejection fraction <35%. All patients underwent a complete echocardiographic evaluation that systematically included(More)
OBJECTIVES The aim of this study was to determine the long-term effects of cardiac resynchronization therapy (CRT) in the European cohort of patients enrolled in the REVERSE (Resynchronization Reverses Remodeling in Systolic Left Ventricular Dysfunction) trial. BACKGROUND Previous data suggest that CRT slows disease progression and improves the outcomes(More)
BACKGROUND Cardiac resynchronization therapy (CRT) decreases mortality, improves functional status, and induces reverse left ventricular remodeling in selected populations with heart failure. We aimed to assess the impact of baseline QRS duration and morphology and the change in QRS duration with pacing on CRT outcomes in mild heart failure. METHODS AND(More)
AIMS The study aimed at evaluating the prevalence of interventricular and intraventricular contractile dyssynchrony in heart failure patients with either normal or prolonged QRS duration. METHODS AND RESULTS Echocardiography and tissue Doppler imaging (TDI) were performed in 158 consecutive patients with advanced left ventricular dysfunction (LVEF<35%);(More)
Pulmonary hypertension (PH), a common complication of left heart diseases (LHD), negatively impacts symptoms, exercise capacity, and outcome. Although the true prevalence of PH-LHD is unknown, a subset of patients might present significant PH that cannot be explained by a passive increase in left-sided filling pressures. The term "out-of-proportion" PH has(More)
OBJECTIVE To evaluate the value of real-time three-dimensional echocardiography (RT3DE) to predict acute response to cardiac resynchronization therapy (CRT). METHODS Sixty consecutive heart failure patients scheduled for CRT were included. RT3DE was performed before and within 48 hours after pacemaker implantation to calculate both left ventricular (LV)(More)
OBJECTIVES We sought a better understanding of the coupling between right ventricular ejection fraction (RVEF) and pulmonary artery pressure (PAP), as it might improve the accuracy of the prognostic stratification of patients with heart failure. BACKGROUND Despite the long-standing view that systolic function of the right ventricle (RV) is almost(More)
AIMS Heart failure (HF) in the elderly carries a poor prognosis. We used the SENIORS dataset of elderly HF patients aged ≥70 years in order to develop a risk model for this population. METHODS AND RESULTS The SENIORS trial evaluated the effects of nebivolol and enrolled 2128 patients ≥70 years with HF (ejection fraction ≤35%, or recent HF admission). We(More)
