Left atrial function and not volume predicts mid-to-late atrial fibrillation after mitral valve repair.
Publication Type: Academic Journal
Source(s): European journal of cardio-thoracic surgery : official journal of the European Association for Cardio-thoracic Surgery [Eur J Cardiothorac Surg] 2023 May 02; Vol. 63 (5).
Abstract: Objectives: Patients undergoing surgical mitral valve repair (MVr) for degenerative mitral regurgitation are at risk of even late postoperative atrial fibrillation (AF). Left atrial (LA) function has been shown superior to LA volume in evaluating the r...
Intermittent fasting attenuates obesity-related atrial fibrillation via SIRT3-mediated insulin resistance mitigation.
Publication Type: Academic Journal
Source(s): Biochimica et biophysica acta. Molecular basis of disease [Biochim Biophys Acta Mol Basis Dis] 2023 Apr; Vol. 1869 (4), pp. 166638. Date of Electronic Publication: 2023 Jan 16.
Abstract: Objective: Atrial fibrillation (AF) is the most common tachyarrhythmia in urgent need of therapeutic optimization. Obesity engenders AF, and its pathogenesis is closely intertwined with insulin resistance (IR), but mechanism-based management is still u...
Diagnostic accuracy of left atrial function and strain for differentiating between acute and chronic myocardial infarction.
Publication Type: Academic Journal
Source(s): BMC cardiovascular disorders [BMC Cardiovasc Disord] 2023 Apr 28; Vol. 23 (1), pp. 218. Date of Electronic Publication: 2023 Apr 28.
Abstract: Background: The cardiac magnetic resonance tissue tracking (CMR-TT) technique was used to obtain left atrial strain and strain rate in patients with myocardial infarction (MI) and to evaluate the utility of this technique in the quantitative assessment...
Development of a novel low-order model for atrial function and a study of atrial mechano-electric feedback.
Publication Type: Academic Journal
Source(s): Computers in biology and medicine [Comput Biol Med] 2023 Jun; Vol. 159, pp. 106697. Date of Electronic Publication: 2023 Feb 17.
Abstract: Numerical models of the cardiovascular system have largely focused on the function of the ventricles, with atrial function often neglected. Furthermore, the time-varying elastance method that prescribes the pressure-volume relationship rather than calc...
Intravenous bolus potassium: Appropriate indication in recurrent ventricular fibrillation.
Publication Type: Editorial & Opinion
Source(s): The American journal of emergency medicine [Am J Emerg Med] 2023 Jun; Vol. 68, pp. 193. Date of Electronic Publication: 2023 Apr 12.
Abstract: Competing Interests: Declaration of Competing Interest The authors declare that there is no conflict of interest.
Natriuretic peptides as predictors for atrial fibrillation recurrence after catheter ablation: A meta-analysis.
Publication Type: Academic Journal
Source(s): Medicine [Medicine (Baltimore)] 2023 May 12; Vol. 102 (19), pp. e33704.
Abstract: Background: Catheter ablation (CA) has become the first-line treatment strategy for atrial fibrillation (AF) but remains with a substantial recurrence rate. The aim of this meta-analysis was to determine the association between baseline natriuretic pep...
Left atrial contraction strain during a Valsalva manoeuvre: A study in healthy humans.
Publication Type: Academic Journal
Source(s): Clinical physiology and functional imaging [Clin Physiol Funct Imaging] 2023 May; Vol. 43 (3), pp. 165-169. Date of Electronic Publication: 2022 Dec 27.
Abstract: Background: Cardiac mechanics are influenced by loading conditions as well as sympathetic tone. Left atrial (LA) contractile function assessed by two-dimensional (2D) strain has been described in the setting of controlled preload alterations; however, ...
Ablation of atrial fibrillation beyond pulmonary vein isolation: Do additional ablation lesions impact left atrial function?
Publication Type: Academic Journal
Source(s): Journal of cardiovascular electrophysiology [J Cardiovasc Electrophysiol] 2023 Feb; Vol. 34 (2), pp. 327-334. Date of Electronic Publication: 2022 Dec 21.
Abstract: Introduction: Electrical isolation of pulmonary veins (PVI) is a cornerstone for atrial fibrillation (AF) ablation. The overall effect of AF ablation, and especially lesions beyond PVI, on left atrial (LA) function is currently poorly understood. Our a...
Prior statin use and the incidence of in-hospital arrhythmia in acute coronary syndrome: A systematic review and meta-analysis.
Publication Type: Academic Journal
Source(s): Indian heart journal [Indian Heart J] 2023 Jan-Feb; Vol. 75 (1), pp. 9-16. Date of Electronic Publication: 2023 Jan 13.
Abstract: Background: The benefit of prior statin use to reduce the incidence of arrhythmia in acute coronary syndrome (ACS) is still a matter of debate. Statins have multiple pleiotropic effects, which may reduce the incidence of in-hospital arrhythmia. A syste...
Right atrial function and fibrosis in relation to successful atrial fibrillation ablation.
Publication Type: Academic Journal
Source(s): European heart journal. Cardiovascular Imaging [Eur Heart J Cardiovasc Imaging] 2023 Feb 17; Vol. 24 (3), pp. 336-345.
Abstract: Aims: Bi-atrial remodelling in patients with atrial fibrillation (AF) is rarely assessed and data on the presence of right atrial (RA) fibrosis, the relationship between RA and left atrial (LA) fibrosis, and possible association of RA remodelling with ...
