Catheter Ablation for Patients with Atrial Fibrillation and Heart Failure: Insights from the Swedish Heart Failure Registry.

Eur J Heart Fail 2022 Jul 2. Epub 2022 Jul 2.

Heart and Vascular Theme, Karolinska University Hospital, Stockholm, Sweden.

Aims: To investigate the association between catheter ablation for atrial fibrillation (AF) and mortality as well as hospitalization for heart failure (HF) in patients with HF across the ejection fraction (EF) spectrum.

Methods: Patients with first-time catheter ablation for AF (ablation group) compared to only medical treated AF patients (no ablation group) were identified from the Swedish Heart Failure Registry between 2005 and 2019. The primary outcome (all-cause mortality/first HF hospitalization) was assessed by Cox regression models in a 1:2 propensity score (PS) matched cohort and pre-specified EF subgroups (preserved EF [HFpEF] [EF≥50%], mildly reduced EF [HFmrEF] [EF 40% to 49%], reduced EF [HFrEF] [EF<40%]) of this cohort.

CHA DS -VASc and R CHA DS -VASc scores predict mortality in high cardiovascular risk population.

Eur J Clin Invest 2022 Jul 1:e13830. Epub 2022 Jul 1.

Unit of Internal Medicine, Fondazione IRCCS Casa Sollievo della Sofferenza, San Giovanni Rotondo (FG), FG, Italy.

Background: The CHA DS -VASc score, widely used to estimate cardioembolic risk in patients with atrial fibrillation (AF), appears to be useful also in predicting vascular adverse events and death in different sets of patients without AF. The R CHA DS -VASc score, which includes renal impairment, allows a better prediction of death and thromboembolism in patients without AF. The aims of our study were to assess, in a large sample of patients at high cardiovascular (CV) risk, i) the correlation between CHA DS -VASc and R CHA DS -VASc with all-cause mortality, and ii) to compare the performances of CHA DS -VASc and R CHA DS -VASc in predicting all-cause mortality.

Accurate segmentation for the left atrium (LA) is a key process of clinical diagnosis and therapy for atrial fibrillation. In clinical, the semantic-level segmentation of LA consumes much time and labor. Although supervised deep learning methods can somewhat solve this problem, a high-efficient deep learning model requires abundant labeled data that is hard to acquire. Read More

The conundrum of the complex relationship between acute kidney injury and cardiac arrhythmias.

Nephrol Dial Transplant 2022 Jul 1. Epub 2022 Jul 1.

Associazione Nefrologica Gabriella Sebastio, Martina Franca, Italy.

Acute kidney injury (AKI) is defined by a rapid increase in serum creatinine levels, reduced urine output, or both. Death may occur in 16%-49% of patients admitted to an intensive care unit with severe AKI. Complex arrhythmias are a potentially serious complication in AKI patients with pre-existing or AKI-induced heart damage and myocardial dysfunction, fluid overload, and especially electrolyte and acid-base disorders representing the pathogenetic mechanisms of arrhythmogenesis.

Process of cerebral edema in the infarct core after reperfusion: A case report.

Medicine (Baltimore) 2022 Jul 1;101(26):e29810. Epub 2022 Jul 1.

Department of Neurology, The Affiliated Brain Hospital of Guangzhou Medical University, Guangzhou, China.

Rationale: It is generally believed that cerebral infarction shows hypoattenuation on computed tomography (CT) scans 12 to 24 hours after onset. Cerebral edema affects the occurrence of hypoattenuation, originating from the inner edge of the infarct and extending to the core. When reperfusion occurs in the infarct, the process of cerebral edema changes significantly, affecting the imaging of cerebral infarction on CT scans. Read More

Distinct propagation patterns of right pulmonary veins through multiple epicardial connections during right atrial pacing and sinus rhythm.

J Cardiovasc Electrophysiol 2022 Jul 1. Epub 2022 Jul 1.

Department of Cardiology, Ageo Central General Hospital, 1-10-10 Kashiwa-za, Ageo city, Saitama, Japan.

A 47-year-old man with symptomatic paroxysmal atrial fibrillation (AF) underwent AF ablation. Activation maps during right atrial pacing and sinus rhythm before the ablation revealed distinctive left atrial (LA) propagations with multiple LA breakthrough sites via epicardial connections. A wide area circumferential ablation was not able to achieve a right pulmonary vein (RPV) isolation and required an inner PV ablation to isolate the RPV. Read More

miR-181b targets semaphorin 3A to mediate TGF-β-induced endothelial-mesenchymal transition related to atrial fibrillation.

J Clin Invest 2022 Jul;132(13)

Cardiovascular Department, Chang Gung Memorial Hospital, Tao Yuan, Taiwan.

Atrial fibrosis is an essential contributor to atrial fibrillation (AF). It remains unclear whether atrial endocardial endothelial cells (AEECs) that undergo endothelial-mesenchymal transition (EndMT) are among the sources of atrial fibroblasts. We studied human atria, TGF-β-treated human AEECs, cardiac-specific TGF-β-transgenic mice, and heart failure rabbits to identify the underlying mechanism of EndMT in atrial fibrosis. Read More

TGF-β1-induced endothelial-mesenchymal transition: a potential contributor to fibrotic remodeling in atrial fibrillation?

J Clin Invest 2022 Jul;132(13)

Institute of Pharmacology, West German Heart and Vascular Center, University Duisburg-Essen, Essen, Germany.

Atrial fibrillation (AF) is the most common cardiac arrhythmia worldwide, with an unmet therapeutic need. Fibrotic remodeling, in which collagen-producing atrial fibroblasts play a crucial role, substantially contributes to arrhythmia promotion and progression. In this issue of the JCI, Lai, Tsai, and co-authors reveal that TGF-β1 promoted endothelial-mesenchymal transition during AF and put forward the notion that, in the adult heart, atrial fibroblasts can originate from different cellular sources.
