BACKGROUND: Cardiac resynchronization therapy (CRT) is a recognized treatment modality for patients with dilated cardiomyopathy (DCM), left bundle branch block, and severe cardiac failure. However, 30% of patients are "nonresponders." Intriguingly, the opposite case has not been reported until recently: Do some patients treated with CRT have a "complete" recovery ...

Cardiac resynchronization therapy (CRT) is now a well-recognized therapeutic option for patients with end-stage heart failure. However, not all patients respond to CRT, and, therefore, preimplantation identification of responders is desirable. The aim of the present study was to investigate whether the degree of left ventricular (LV) dyssynchrony, as assessed ...

Dobutamine echocardiography is commonly used to detect contractile reserve in ischaemic left ventricular (LV) systolic dysfunction, although its sensitivity and specificity are not optimal. We tested the hypothesis that echocardiography with levosimendan could identify contractile reserve in patients with a non-diagnostic dobutamine test. Twenty-two patients with LV ejection fraction <40% ...

BACKGROUND: Right ventricular (RV) function is an important determinant of clinical status in children with hypoplastic left heart syndrome (HLHS). However, assessment of RV function remains challenging because of its complex morphology. We investigated the S/D duration ratio in children with HLHS as a novel index of global RV function. ...
Weber Thomas - - 2007
BACKGROUND: In general, pulse pressure (PP), augmentation index (AIx), and pulse wave velocity (PWV) are directly and positively associated with cardiovascular risk. However, in patients with systolic heart failure, the opposite (ie, an association between a lower PP and a worse outcome) has been reported as well. METHODS AND RESULTS: ...

Although cardiac resynchronization therapy (CRT) is beneficial in patients with drug-refractory New York Heart Association (NYHA) class III/IV heart failure (HF) and left ventricular (LV) dyssynchrony, CRT efficacy is not well established in patients with more advanced HF on inotropic support. Ten patients (age 55 +/- 13 years) with inotrope-dependent ...

Severe chronic mitral regurgitation (MR) is associated with progressive left ventricular (LV) systolic dysfunction. Both afterload reduction and beta-adrenergic blockade have been suggested as methods for preventing LV dysfunction in asymptomatic patients with MR and normal LV function, who are therefore not yet candidates for surgical intervention. The objective of ...

It has been reported that carvedilol improves cardiac sympathetic nerve activity (CSNA) in patients with dilated cardiomyopathy (DCM). However, the influence of carvedilol on cardiac (123)I-meta-iodobenzylguanidine (MIBG) scintigraphic findings and left ventricular (LV) remodelling has not been determined in DCM patients. In 30 patients with DCM and 10 normal controls, ...
Paraskevaidis Ioannis A - - 2008
BACKGROUND: Several indices have been proposed in order to better evaluate chronic mitral regurgitation, however, none of them is unique, thus underlying the diagnostic deficiency. We aimed to investigate the role of long axis contraction in both ventricles in patients with non-ischemic asymptomatic mitral regurgitation (MR). METHODS: Eighty-nine patients (40 ...

BACKGROUND: Idiopathic premature ventricular complexes (PVCs) usually are considered benign, even when frequent. However, case reports have demonstrated a possible link between frequent PVCs and left ventricular (LV) dysfunction. In addition, frequent PVCs recently were demonstrated to be associated with increased LV dimensions and cardiomyopathy. METHODS: Among 60 consecutive patients ...
