How should we optimize cardiac resynchronization therapy?
Optimization of cardiac resynchronization therapy is increasingly performed. Numerous methods have been proposed, many being echocardiographic. Both the technique and the timing of optimization are contentious. Whether acute haemodynamic benefits translate into long-term improvements in remodelling, symptoms, or prognosis is unknown. Recent guidelines from the American Society of Echocardiograp...
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 کاملShould we use the rate-adaptive AV delay in cardiac resynchronization therapy-pacing?
AIMS Recommendations for programming the rate-adaptive AV delay in CRT. METHODS AND RESULTS In cases of continual biventricular pacing, the optimal AV delay in CRT (AVD(opt)) is the net effect of the pacemaker-related interatrial conduction time (IACT), duration of the left-atrial electromechanical action (LA-EAC(long)), and the duration of the left-ventricular latency period (S(V)-EAC(short)...
متن کاملInformed consent in cardiac resynchronization therapy: what should be said?
Cardiac resynchronization therapy (CRT) for the treatment of heart failure (HF) raises complex problems for informed consent. CRT with and without defibrillator backup has been demonstrated in clinical trials to improve symptoms from HF and decrease mortality.1–4 A CRT pacemaker (CRT-P) may improve symptoms and reduce mortality in selected patients, even without offering the specific protection...
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...
