Impact of stepwise ablation on the biatrial substrate in patients with persistent atrial fibrillation and heart failure.
BACKGROUND Ablation of persistent atrial fibrillation can be challenging, often involving not only pulmonary vein isolation (PVI) but also additional linear lesions and ablation of complex fractionated electrograms (CFE). We examined the impact of stepwise ablation on a human model of advanced atrial substrate of persistent atrial fibrillation in heart failure. METHODS AND RESULTS In 30 patie...
متن کاملAcute improvement of atrial mechanical stunning after electrical cardioversion of persistent atrial fibrillation: comparison between biatrial and single atrial pacing.
OBJECTIVE To evaluate the acute effects of atrial pacing at different pacing sites on mechanical stunning after cardioversion of atrial fibrillation (AF). SETTING Tertiary referral centre. PATIENTS 20 patients with persistent AF were studied. INTERVENTIONS Spontaneous echo contrast (SEC), left atrial appendage emptying velocity (LAAEV), and left atrial appendage emptying fraction (LAAEF) ...
متن کاملAtrial fibrillation and heart failure.
Atrial fibrillation (AF) and congestive heart failure (CHF) are the new epidemics of the third millennium due to ageing of the population and the success of new therapies for acute cardiac illnesses that, in the past, were fatal. The interactions between AF and CHF are only partially understood, and the effectiveness of drugs as well as that of non-pharmacological interventions remains often di...
متن کاملAtrial fibrillation in heart failure.
Heart failure (HF) and atrial fibrillation (AF) are highly prevalent debilitating conditions that often coexist and are frequently encountered in clinical practice. The presence of chronic AF is a marker of worse prognosis in patients with HF, and the onset of new AF in those with chronic HF is associated with increased morbidity and mortality. Advances in the development of novel drugs, nonpha...
متن کاملAtrial Fibrillation and Heart Failure.
Atrial fibrillation is common in heart failure patients and is associated with increased mortality. Pharmacologic trials have not shown any survival benefit for a rhythm control over a rate control strategy. It has been suggested that sinus rhythm is associated with a survival benefit, but that the risks of anti-arrhythmic drug treatment and poor efficacy offset the beneficial effect. Catheter ...
