resultant striking increase in morbidity and mortality. The transition to symptomatic heart
failure is accompanied by further activation of neurohormonal and cytokine systems, as well …

The prognostic significance of the right ventricle (RV) has recently been recognised in
several conditions, primarily those involving the left ventricle, the lungs and their vascular …

Background Cardiac resynchronization reduces symptoms and improves left ventricular
function in many patients with heart failure due to left ventricular systolic dysfunction and …

Objectives: This study was designed to predict the response and prognosis after cardiac
resynchronization therapy (CRT) in patients with end-stage heart failure (HF). Background …

Background Indications for cardiac-resynchronization therapy (CRT) in patients with heart
failure include a prolonged QRS interval (≥ 120 msec), in addition to other functional …

Echocardiography plays an evolving and important role in the care of heart failure patients
treated with biventricular pacing, or cardiac resynchronization therapy (CRT). Numerous …

Background—The relative merits of left ventricular (LV) dyssynchrony, LV lead position, and
myocardial scar to predict long-term outcome after cardiac resynchronization therapy remain …

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 …

Cardiac resynchronization therapy (CRT) has been proposed as an alternative treatment in
patients with severe, drug-refractory heart failure. The clinical results are promising, and …

BACKGROUND: Intracardiac electrograms can be used to guide left ventricular (LV) lead
placement during implantation of cardiac resynchronization therapy (CRT) devices …
