Impact of Atrial Programmed Electrical Stimulation Techniques on Unipolar Electrogram Morphology

ConclusionAPES results in significant changes in U ‐AEGM morphology, including width, amplitude and fractionation. The impact of APES differed between APES sequence and between patients with and without AF. These findings suggest that APES could be useful to identify AF related conduction abnormalities in the individual patient.This article is protected by copyright. All rights reserved.

Atrial fibrillation (AF) is common in patients with the left ventricular assist device (LVAD), but the little is known about the impact of AF on clinical outcomes. The aim of this study is to investigate the impact of AF on outcomes in patients with the HeartMate 3 (HM3) LVAD.

Falls and syncope are associated with increasing age and cause considerable morbidity and mortality in the elderly.1 Beyond age, traditionally recognized risk factors for falls include unsteady gait, muscle weakness, impaired cognition, and polypharmacy. Malik et  al2 present a detailed systematic review evaluating the role of atrial fibrillation (AF) in falls/syncope and conclude that AF is independently associated with falls (odds ratio [OR], 1.19; 95% CI, 1.07-1.33) and syncope (OR, 1.88; 95% CI, 1.20-2.94) based on a meta-analysis of 7 and 3 observation al studies, respectively.

To examine the potential association of atrial fibrillation (AF) to syncope and falls, we undertook a systematic review and meta-analysis given the increasing prevalence of AF in older adults as well as emerging data that it is a risk factor for dementia.

The purpose of this study was to evaluate the effectiveness of topical amiodarone applied to the atria and pulmonary veins at the time of lung transplantation (LTx) in decreasing postoperative atrial fibrillation (POAF).

The left atrium (LA) in heart transplant (HT) recipients is a surgically created chamber from variable portions of donor and recipient. In the non-HT patients there is strong evidence that left atrial volume (LAV) is a robust predictor of cardiovascular outcomes such as atrial fibrillation, stroke, heart failure and cardiovascular death. Thus, we thought to 1) characterize LA size in HT recipients and 2) investigate the implications of “new” LA volume on HT outcomes.

This study deals with the clinical, echocardiographic, and prognostic outcomes in these patients. Prognostic scores, as MAGGIC (Meta-analysis Global Group in Chronic Heart Failure) score, may help to predict the outcomes.MethodsFrom a single center, 47 patients with AF, HF, and left ventricular ejection fraction (LVEF)

ConclusionThis propensity score analysis demonstrated that the EVT patients with acute ICAD-related MCA M1 occlusion had similar angiographic and clinical outcomes compared to those with M1 embolism on a  similar baseline condition.

Functional mitral regurgitation (FMR) and atrial fibrillation (AF) are common in patients undergoing left ventricular assist device (LVAD) implantation. However, the impact of FMR and AF on clinical outcomes is uncertain. The aim of this study is to investigate the prognostic significance of FMR and AF in patients with LVAD.

Atrial fibrillation (AF) is a common complication after lung transplantation that is associated with adverse outcomes. While some evidence-based protocols exist for prophylaxis and treatment of AF after general thoracic surgery, there lacks necessary evidence-based recommendations in the lung transplant population to standardize care delivery. This paucity of literature contributes to limited evidence-based guidelines for treatment and prophylaxis of AF in this specialty population. The purpose of this descriptive study was to identify the evidence-based practices for prophylaxis and treatment of AF at lung transplant cent...
