Selecting patients for cardiac resynchronization therapy: electrical or mechanical dyssynchrony?
Cardiac resynchronization therapy (CRT) markedly reduces morbidity and mortality in patients with heart failure and prolonged QRS duration. Landmark trials have included over 4000 patients based on their electrocardiogram. A few small, observational, non-randomized, single centre studies of short duration have suggested that echocardiographic measurement of mechanical dyssynchrony may better id...
متن کاملSelecting patients for cardiac resynchronization therapy: the fallacy of echocardiographic dyssynchrony.
Cardiac resynchronization therapy (CRT) reduces morbidity and mortality in patients with heart failure. International guidelines unanimously endorse QRS prolongation to identify candidates for implantation, based on over 4,000 patients randomized in landmark trials. Small, observational, nonrandomized studies with surrogate end points have promoted echocardiography as a superior method of patie...
متن کاملHow many patients need cardiac resynchronization therapy?
For patients with moderate or severe heart failure who have evidence of cardiac dyssynchrony there is overwhelming evidence that cardiac resynchronization therapy (CRT) improves symptoms substantially, reduces morbidity, and prolongs life. The CARE-HF programme demonstrated that CRT reduced all-cause mortality by 40% and cardiovascular mortality by about 45%. The COMPANION trial, which was stop...
متن کاملSelection for Cardiac Resynchronization Therapy
SEE PAGE 969 C ardiac resynchronization therapy (CRT) is a highly effective treatment for some patients with heart failure. Current guidelines recommend the implantation of CRT devices in patients with left ventricular (LV) dysfunction and electrical dyssynchrony, evidenced by a left bundle branch block (1). Unfortunately, not all patients suitable for CRT derive symptomatic benefit—an unsatisf...
متن کاملCardiac-resynchronization therapy.
Cardiac resynchronization therapy (CRT) addresses abnormal left ventricular (LV) activation that produces detrimental effects on cardiac systolic and diastolic function. CRT improves symptoms and ventricular performance, promotes reverse remodeling, and decreases mortality and hospitalization in patients with congestive heart failure (CHF). Atrial-synchronized biventricular stimulation reverses...
