Botulinum Toxin Injection in the Autonomic Ganglion Plexi to Prevent Post-operative Atrial Fibrillation: More than a Cosmetic Treatment
Postoperative atrial fibrillation (POAF) frequently complicates cardiac surgery, and is associated with prolonged hospitalization, increased risk of development of AF during follow-up, stroke and mortality. Several comorbidities predispose to POAF, among which inflammation and oxidative stress, but also structural atrial remodeling is associated with an increased POAF risk(1). One potential pathway that caught attention recently is the autonomic dysbalance during cardiac surgery in relation to the occurrence of POAF.

Anticoagulation in elderly patients with nonvalvular atrial fibrillation: A balancing act
Atrial fibrillation (AF) is a major global health burden because of its rising prevalence and associated complications such as stroke and mortality.1 In the 2010 Global Burden of Disease study, approximately 33 million people were estimated to have AF, but this number is projected to increase exponentially due to the ageing population1

Impact of dense ‘Smoke’ detected on Transesophageal Echocardiography on stroke-risk in patients with atrial fibrillation undergoing catheter ablation
Spontaneous echocardiographic contrast ( ‘Smoke’) within the left atrial cavity on transesophageal echocardiography (TEE) suggests low blood flow velocities in the heart that may consequently lead to thromboembolic (TE) events.

Harmonized Outcome Measures for Use in Atrial Fibrillation Patient Registries and Clinical Practice
Atrial fibrillation (AF) affects an estimated 33 million people worldwide, leading to increased mortality and an increased risk of heart failure and stroke. Many AF patient registries exist, but the ability to link and compare data across registries is hindered by differences in the outcome measures collected by each registry and a lack of harmonization.

EP News: Clinical
Sindet-Pedersen et al (J Am Coll Cardiol 2018;72:1790, PMID 30286922) investigated the risk of bleeding, ischemic stroke, myocardial infarction (MI), and all-cause mortality associated with direct oral anticoagulants (DOACs) compared with vitamin K antagonists (VKAs) in combination with aspirin, clopidogrel, or both in patients with atrial fibrillation (AF) after MI and/or percutaneous coronary intervention (PCI). Overall, 3222 patients were included in the retrospective registry analysis; 875 (27%) were treated with VKA+single antiplatelet therapy (SAPT), 595 (18%) were treated with DOAC+SAPT, 1074 (33%) were treated wi...

Electrical isolation of the left atrial appendage increases the risk of ischemic stroke and transient ischemic attack regardless of postisolation flow velocity
Electrical isolation of the left atrial appendage (LAA) is associated with a lower rate of atrial fibrillation (AF) recurrence in patients undergoing radiofrequency catheter ablation. However, LAA isolation can significantly impair LAA contractility.

Left Atrial Appendage Closure Device Implantation in Patients with Prior Intracranial Hemorrhage
The Watchman ™ device (Boston Scientific, MN), used for left atrial appendage closure (LAAC) was approved for stroke prevention in patients with atrial fibrillation (AF) and an appropriate rationale to avoid long-term oral anticoagulation. Patients with AF and prior intracranial hemorrhage (ICH) were excluded from clinical trials due to perceived risks of peri-operative anticoagulation.

Atrial Fibrillation Occurring During Head-up Tilt Test: Once detected, AF should be monitored, regardless of how it is detected
Atrial fibrillation (AF) often progresses to more sustained forms and raises the risk of ischemic stroke or sinus node dysfunction (SND). However, there has been no data on the clinical outcomes of AF developed during head-up tilt testing (HUT).

CHA2DS2-VASc scores and Intermountain Mortality Risk Scores for the joint risk stratification of dementia among patients with atrial fibrillation
High CHA2DS2-VASc scores in atrial fibrillation (AF) patients are generally associated with increased risks of stroke and dementia. At lower CHA2DS2-VASc scores, there remains an unquantifiable cranial injury risk, necessitating an improved risk assessment method within these lower-risk groups.

Left Atrial Appendage Closure Device Implantation in Patients with Atrial Fibrillation and Prior Intracranial Hemorrhage “No Man Left Behind”
Several LAA closure devices have been developed for patients with atrial fibrillation (AF) seeking an alternative to long-term oral anticoagulation (OAC). The PROTECT AF trial was the first multicenter randomized controlled trial (RCT) comparing LAA closure device vs. OAC with Warfarin. Primary safety events were statistically more frequent in the device group (7.4% vs. 4.4%). At a mean follow up of 3.8 years LAA closure device showed superiority for the primary efficacy endpoint (i.e., composite of stroke, cardiovascular death and systemic embolism), with a 34% relative risk reduction in total mortality1-3 However, with t...

Cryoballoon Pulmonary Vein Ablation and Left Atrial Appendage Closure Combined Procedure: a long term follow up analysis Cryoablation with Concomitant Left Atrial Appendage Closure
combined left atrial appendage closure (LAAC) and cryo-energy pulmonary vein isolation (PVI) procedure has been proven safe and effective in managing stroke in patients with non-valvular atrial fibrillation (AF), although most data refer to procedures performed using radiofrequency (RF) as main energy source.

Atrial fibrillation patients with hypertrophic cardiomyopathy: Do we need new stroke risk stratification?
Due to very high thromboembolic risk, life-long oral anticoagulation is recommended in all hypertrophic cardiomyopathy (HCM) patients with non-valvular atrial fibrillation (NVAF).1-3 We read with great interest the paper by Tsuda et al.4 who rightly emphasized the importance of HCM on thromboembolism in patients with AF.
