Cardiac Resynchronization Therapy and Atrial Fibrillation.

Synergistic effects of cardiac resynchronization therapy and Bachmann's bundle pacing on heart failure with atrial tachyarrhythmias.

Cardiac resynchronization therapy (CRT) is electrical resynchronization of the ventricles. Bachmann's bundle (BB) pacing is considered to be electrical resynchronization of the atria. Atrial fibrillation (AF) and congestive heart failure (HF) often coexist in the same patient. A 69 year-old man who underwent CRT combined with BB pacing for HF and atrial tachycardias or atrial fibrillation (AF) ...

Comparison of the rhythm control treatment strategy versus the rate control strategy in patients with permanent or long-standing persistent atrial fibrillation and heart failure treated with cardiac resynchronization therapy - a pilot study of Cardiac Resynchronization in Atrial Fibrillation Trial (Pilot-CRAfT): study protocol for a randomized controlled trial

BACKGROUND The only subgroups of patients with heart failure and atrial fibrillation in which the efficacy of cardiac resynchronization therapy has been scientifically proven are patients with indications for right ventricular pacing and patients after atrioventricular junction ablation. However it is unlikely that atrioventricular junction ablation would be a standard procedure in the majority...

CRT-D therapy in patients with left ventricular dysfunction and atrial fibrillation.

The number of patients with atrial fibrillation and congestive heart failure has steadily increased in the United States. The presence of atrial fibrillation increases morbidity and mortality for patients with left ventricular dysfunction. The emergence of cardiac resynchronization therapy to improve symptoms and survival from congestive heart failure may provide benefits for those with atrial ...

Cardiac resynchronization therapy in chronic atrial fibrillation: Impact on left atrial size and reversal to sinus rhythm

Cardiac Resynchronization Therapy in Patients with Atrial Fibrillation - Worth the Effort?

Congestive heart failure (CHF) and atrial fibrillation (AF) are two increasingly common conditions that predispose to each other and frequently coexist. Cardiac resynchronization therapy(CRT) has emerged as an important therapeutic modality for selected patients with end-stage CHF. However, despite the high prevalence of AF in patients eligible for CRT, almost all the randomized clinical trials...

Pacemaker-mediated tachycardia in an unconventional resynchronization device.

A 67-year-old male patient with heart failure and permanent atrial fibrillation underwent atrio-ventricular nodal ablation and a biventricular device implantation. Instead of a standard cardiac resynchronization therapy device, a DDD pacemaker was implanted with the left ventricular lead in the atrial channel. After the implant, a pacemaker-mediated tachycardia caused by T wave oversensing by t...
