Atrial fibrillation itself could directly lead to HFpEF via left atrium dilatation and loss of atrial systole, which impairs the diastolic left ventricular (LV) function and subsequently the cardiac output. In sinus rhythm atrial contraction is estimated to contribute up to 20% of the cardiac output. It is noteworthy that atrial systole in adults

Some other patients clearly show a single arrhythmogenic pulmonary vein that sometimes can be suspected only by properly analyzing the surface ECGs, capturing AF beginning [21]. An ablative

Frontier in the Treatment for Atrial Fibrillation Electrical

Atrial fibrillation (AF) is not only the most common arrhythmia in humans, but the persistent form of this dysrhythmia is also one of the most challenging conditions to treat in clinical medicine. Whilst paroxysmal AF (PAF) responds very well to pulmonary vein isolation (PVI), persistent AF (PersAF) does not [1,2].

Results and Implications of the FIRE AND ICE Trial

Electrical isolation of the pulmonary veins is the generally accepted ( cornerstone ) approach to treat symptomatic atrial fibrillation (AF) by catheter ablation.1,2 Pulmonary-vein isolation (PVI) can be achieved either by circumferential heating ( fire ) or freezing ( ice ) of the left atrial tissue surrounding the pulmonary veins.

Aim: Both circumferential pulmonary vein ablation (CPVA) and segmental pulmonary vein isolation (SPVI) are used to tre-at atrial fibrillation (AF), though it is not clear which of the two techniques is preferable. Both have been analyzed in consecuti-ve case series on a randomized basis regardless of the clinical profile involved.

Catheter ablation of atrial fibrillation: what is the best

Since the first report of radiofrequency catheter ablation curing atrial fibrillation (AF) nearly a decade ago (1), numerous techniques have evolved, from linear ablation to modify the reentrant substrate for AF (1,2), to electrical isolation of pulmonary vein(s) to eliminate triggers of AF (3 5), to hybrid approaches of circumferential

PeAF and LSPAF are chronic state of the disease with progressive atrial fibrosis and evolving pulmonary and non-pulmonary vein (non-PV) triggers (2). It is still unclear whether substrate ablation alone or the elimination of triggers of AF or a combination of both, is the ideal ablation approach in this subset of AF population (4).
