BACKGROUND: Atrial fibrillation is the commonest cardiac dysrhythmia. It is associated with significant morbidity and mortality. There are two approaches to the management of atrial fibrillation: controlling the ventricular rate or converting to sinus rhythm in the expectation that this would abolish its adverse effects. OBJECTIVES: To assess the effects of pharmacological cardioversion of atrial fibrillation in adults on the annual risk of stroke, peripheral embolism, and mortality...

BACKGROUND: Atrial fibrillation increases stroke risk and adversely affects cardiovascular haemodynamics. Electrical cardioversion may, by restoring sinus rhythm, improve cardiovascular haemodynamics, reduce the risk of stroke, and obviate the need for long-term anticoagulation. OBJECTIVES: To assess the effects of electrical cardioversion of atrial fibrillation or flutter on the risk of thromboembolic events, strokes and mortality (primary outcomes), the rate of cognitive decline, quality of life, the use of anticoagulants and the risk of re-hospitalisation (secondary outcomes) in adults (>18 years)...

Data from the Japan cardiovascular surgery database from 2013 to 2014 were analyzed to demonstrate the mortality rate and choice of surgical procedures, especially concerning the selection of valve prosthesis for each valve position and patient age group, and the effects of preoperative complications on mortality and prosthetic valve selection. The proportion of each surgical procedure was compared for each patient age in the aortic, mitral, and tricuspid positions. The proportion of mechanical valve prostheses was 23...

BACKGROUND: Current epidemiological data suggests that postoperative atrial fibrillation or atrial flutter (POAF) causes significant morbidity and mortality after cardiac surgery. The literature for prophylactic management of POAF is limited, resulting in the lack of clear guidelines on management recommendations. AIM: To examine the efficacy of prophylactic rate control agents in reducing the incidence of new-onset POAF in patients undergoing elective cardiac surgery...

BACKGROUND: The risk of stroke and thromboembolism in atrial fibrillation is established. There are clear guidelines in anticoagulation management of patient's with atrial fibrillation, however, the evidence surrounding the risk of thromboembolism in patients with atrial flutter is not as clear. We hypothesized that atrial flutter would have indicators of less risk for thromboembolism compared with atrial fibrillation on transesophageal echocardiography (TEE); thereby possibly leading to a lower stroke risk...

OBJECTIVES: Ocular flutter (OF) and opsoclonus are considered a continuum with a similar pathogenesis. Due to the rarity of this disease in the adult population, little is known about the brain morphological changes in the chronic phase of the disease. PATIENTS AND METHODS: Six magnetic resonance imaging from adults with previous history of OF/Opsoclonus and 12 healthy patients (paired by age and sex) were analyzed in order to identify the long term cortical thickness pattern in this rare disease by using Freesurfer...

Previous working memory (WM) research based on non-human primate electrophysiology and human EEG has shown that frontal brain regions maintain frequencies of flutter stimulation across different sensory modalities by means of a supramodal parametric WM code. These findings imply that frontal regions encode the memorized frequencies in a sensory-unspecific, quantitative format. Here, we explored which brain regions maintain information about frequencies provided by different sensory modalities at the level of activity pattern across fMRI voxel populations...

Tamer Akel, James Lafferty
BACKGROUND: Atrial fibrillation is a common cardiac arrhythmia with increasing prevalence in the aging population. It is a major cause of emergency department visits worldwide. Vernakalant, a relatively new antiarrhythmic drug with selectively preferential effects on the atrial tissue is currently used in many European countries for the termination of recent-onset atrial fibrillation. Presently, the drug is still not approved by the United States Food and Drug Administration due to safety concerns...

2014 American Association for Thoracic Surgery (AATS) guidelines recommend beta blocker for prevention and management of perioperative atrial fibrillation and flutter for thoracic surgical procedures. In recent years, transdermal patch of bisoprolol (TDPB) has become available in Japan. We examined the efficacy of TDPB for paroxysmal atrial fibrillation (PAF) after open heart surgery. Among 289 patients who had undergone open heart surgery in our hospital from December 2013 to April 2016, 48(16.6%)patients, for whom TDPB was used for PAF, were analyzed retrospectively...

REVIEW
Ronak Shah, Elizabeth Zhou
Patients with atrial fibrillation and flutter routinely require transesophageal echocardiography with cardioversion. It is not uncommon to encounter patients with reduced ejection fractions, coronary artery disease, prior cardiac surgery, or obstructive sleep apnea. The anesthesiologist must carefully evaluate the patient and any available laboratory and study findings to assess for potential complications after anesthesia. Appropriate anesthetics must be chosen based on the preoperative evaluation. Additionally, because most of these cases are done without a secured airway, emergency medications and airway equipment must be readily available...

INTRODUCTION: Oscillatory positive pressure devices (OPEP) can be used as adjuncts to improve sputum clearance in chronic obstructive pulmonary disease (COPD), though the evidence base is incomplete. The attitudes of physiotherapists towards these devices in the care of patients with COPD is unknown. In addition, actual use compared with the prescription of medications has not been studied. METHODS: We analysed English prescribing data, obtained from OpenPrescribing...

A 71-year-old man with no history of coronary artery disease presented with palpitations to the emergency department. The 12-lead ECG showed a regular tachycardia with wide QRS complexes (220 bpm) suggestive of ventricular tachycardia. Instead invasive electrophysiological investigation revealed typical atrial flutter as underlying arrhythmia. The altered QRS morphology resulted from displacement of the heart into the right hemithorax due to right-sided pneumonectomy in combination with bundle branch block.
