Cardiac resynchronization therapy

Current Cardiology Reports, 2002
Despite advances in medical therapy for patients with congestive heart failure, morbidity and mortality remain high. Conventional atrioventricular pacing with a short atrioventricular delay was first introduced as a nonpharmacologic treatment for patients with severe heart failure.

Cardiac resynchronization therapy

Nursing, 2007
About 30% of patients with left ventricular systolic dysfunction also have ventricular conduction delays (prolonged QRS duration greater than 0.12 second) most frequently seen as left bundle branch block. This intraventricular conduction delay causes nonsynchronous ventricular activation between the right ventricle and the left ventricle (or ...

On the Underutilization of Cardiac Resynchronization Therapy

Journal of Cardiac Failure, 2014
Cardiac resynchronization therapy (CRT) is an exciting therapy that can treat patients with systolic heart failure and left ventricular dysfunction who have a wide QRS complex. Indications for its use have been refined and expanded based on recent clinical data and guidelines, yet the rate of new CRT implants in the United States has not changed much ...

Is His‐optimized superior to conventional cardiac resynchronization therapy in improving heart failure? Results from a propensity‐matched study

Pacing and clinical electrophysiology : PACE, 2021
His bundle pacing (HBP), alone or optimized in association with coronary sinus pacing (HBP+LV) has recently been proposed as an alternative to conventional cardiac resynchronization therapy (CRT).

Cardiac resynchronization therapy in cardiomyopathies

Journal of Cardiovascular Medicine, 2014
Cardiomyopathies are a heterogeneous group of diseases of the myocardium that represent a major cause of morbidity and mortality due to progressive heart failure or sudden death. Cardiac resynchronization therapy has become an essential therapeutic tool in the treatment of heart failure patients today.

Cardiac Resynchronization Therapy

Progress in Cardiovascular Diseases, 2006
Left ventricular (LV) dysynchrony, generally defined as the effect of intraventricular conduction defects or bundle branch block to produce nonsynchronous ventricular activation, places the failing heart at a further mechanical disadvantage. The deleterious effects of ventricular dysynchrony include suboptimal ventricular filling, paradoxical septal ...

Indications for Cardiac Resynchronization Therapy

Cardiology Clinics, 2014
Initial studies established patient selection criteria for cardiac resynchronization therapy (CRT) as left ventricular ejection fraction less than or equal to 35%, QRS greater than or equal to 120 ms, and New York Heart Association 3-4. Based on newer data, post hoc analyses, and meta-analyses, these criteria have been refined and guidelines updated ...

Future of Cardiac Resynchronization Therapy

Future Cardiology, 2008
Cardiac resynchronization therapy (CRT) has proven to be a beneficial treatment option in patients with severe drug refractory heart failure in the presence of electromechanical dyssynchrony. More recent trials have demonstrated mortality benefits associated with CRT, and even further reductions when combined with an internal cardiac defibrillator ...

Optimization of Cardiac Resynchronization Therapy

Echocardiography, 2008
Cardiac resynchronization is now an accepted and widespread therapy for patients with left ventricular (LV) systolic dysfunction. However, there are still a significant number of patients that do not appear to gain benefit, and this is currently the focus of a great deal of research.

Cardiac Resynchronization Pacing Therapy

Cardiology, 2004
Approximately one third of patients with congestive heart failure and systolic dysfunction have an intraventricular conduction delay that is manifested as a QRS duration >120 ms. An intraventricular conduction delay adversely affects ventricular performance by causing dyssynchrony in ventricular activation.
