Left Atrial Deformation in Heart Failure: A Clinical Update
2023, Current Problems in CardiologyPredictors and Mechanisms of Atrial Fibrillation in Patients With Hypertrophic Cardiomyopathy
2020, American Journal of CardiologyCitation Excerpt :The initiation and maintenance of AF is complex (Figure 5). LV fibrosis may lead to increased LV filling pressures and a chronically increased LA pressure, leading to LA dilatation.18 Fibrosis within the left atrial wall may additionally interfere with local atrial conduction.19–21
Isolated Left Atrial Standstill in Patients with Hypertrophic Cardiomyopathy and Atrial Fibrillation after Restoration of Sinus Rhythm
2019, Journal of the American Society of EchocardiographyIndications for permanent pacing in dogs and cats
2019, Journal of Veterinary CardiologyCitation Excerpt :In veterinary medicine, it has been described that, perhaps, a sub-population of dogs with third-degree AVB associated with structural heart disease could have the greatest advantage from physiologic VDD pacing stimulation because of the presence of AV synchrony and not-fixed RR interval compared with VVI pacing [110]. In fact, by pacing the ventricle after the atrial contraction, physiologic PMs help avoid atrial contraction against a closed AV mitral valve and may limit mitral valve insufficiency, thereby decreasing mean left atrial pressures [139–143]. Lower left atrial pressures associated with prolonged diastolic filling time and appropriate AV synchrony may enhance left ventricular filling and improve systolic performance [142].
Influence of atrial fibrillation on oxygen uptake and exercise tolerance in cardiovascular patients; close association with heart rate response
2019, IJC Heart and VasculatureCitation Excerpt :Regarding the hemodynamic derangement of AF, rhythm irregularity and loss of atrial contribution to LV filling impair cardiac output in AF patients [3]. Exercise capacities in AF patients have been shown to be impaired by multiple pathways, such as endothelial dysfunction or neurohumoral factors [16,17]. In addition, hemodynamic effects derived from AF change according to the exercise level.
Determinants of left atrial volume index in patients with aortic stenosis: A multicentre pilot study
2017, Archives of Cardiovascular DiseasesCitation Excerpt :The increase in LA volume is a reflection of elevated LV filling pressures in the absence of congenital heart disease, mitral valve or primary atrial pathology. In a non-compliant left ventricle, as the LA is exposed to the pressures of the LV during diastole, LA pressure rises to maintain adequate LV filling [35]; the chronically elevated LA wall tension leads to chamber dilatation. LA volume is therefore an expression of the chronicity of exposure to abnormal filling pressures [10].
