  • peak atrial
  • 16 Peak atrial strain (the peak of the positive deflection occurring during the reservoir phase, when the right ventricle contracts and the right atrium fills against a closed tricuspid valve) is perhaps the most used parameter of RA function. (elsevier.pt)
  • RA volume 18 - for the same amount of blood received, dilated atria have lower peak atrial strain than non-dilated atria ( Figure 3 ). (elsevier.pt)
  • In accordance with the above, since a chronic significant left-to-right shunt through an ASD leads to a varying degree of RA dilatation due to volume overload, peak atrial strain should be decreased in ASD patients, who have dilated atria. (elsevier.pt)
  • myocardial
  • Strain (SI) and strain rate (SR) measure regional myocardial deformation and may be a new technique to assess phasic atrial function. (bmj.com)
  • Speckle tracking echocardiography (STE) for two-dimensional (2D) strain analysis is a new tool to assess myocardial function. (revportcardiol.org)

  • We hypothesized that myocardial ischemia may affect ANP secretion and that reperfusion therapy for acute myocardial infarction can preserve endocrine function of the heart. (ahajournals.org)
  • Progressive myocardial stiffness of the LV in patients with hypertrophic cardiomyopathy (HCM) impedes early diastolic filling and left atrial (LA) emptying functions. (biomedcentral.com)
  • pulmonary venous
  • These LA functions mechanically facilitate the transition between flow through the pulmonary venous circulation and the intermittent filling of the left ventricle [ 6 , 7 ]. (kjim.org)
  • Furthermore, advances in catheter ablation procedures used for the treatment of drug-refractory atrial fibrillation require the need for detailed knowledge of left atrial and pulmonary venous morphology as well of atrial wall characteristics. (hindawi.com)
  • Subjects were excluded if they did not speak English or if any of the following was present: associated congenital heart defects that required cardiac surgery (except for partial anomalous pulmonary venous return associated with a sinus venosus ASD or a very small patent ductus arteriosus), congestive heart failure or pulmonary hypertension, anomalies that affect cognitive function, or chronic disease likely affecting development, such as bronchopulmonary dysplasia.

  • assessment
  • In this elegant study, the authors performed a comprehensive assessment of LV function, showing that extensive LV remodeling at baseline is associated with poor improvement after CRT. (onlinejacc.org)
  • Characterization of LA booster-pump function may be useful for the assessment of the symptomatic status in patients with severe AS patients and limited physical activity. (biomedsearch.com)
  • This review article discusses the role of cardiac magnetic resonance and computed tomography in assessment of left atrial size, its normal and abnormal morphology, and function. (hindawi.com)
  • cognitive function
  • Additionally, AF can also result in other complications, such as adverse hemodynamics, impaired cognitive function or dementia, congestive heart failure and tachycardia-induced cardiomyopathy ( 6 ). (spandidos-publications.com)
  • Conclusions- Use of CPB was not associated with changes in cognitive function in our subjects who underwent repair of an ASD. (ahajournals.org)
  • The contribution of CPB to changes in cognitive function in children could be more precisely defined if preoperative and postoperative measures of cognitive function were available, as is often the case for adult patients. (ahajournals.org)
  • Furthermore, selection of a suitable comparison group of children matched for the multitude of factors that contribute to cognitive function is imperfect, as is post hoc statistical adjustment. (ahajournals.org)
  • We therefore performed a prospective observational study in which we evaluated cognitive function in subjects both before and after surgical repair of an atrial septal defect. (ahajournals.org)
  • cardiovascular
  • Association of Left Atrial Function Index with Atrial Fibrillation and Cardiovascular Disease: The Framingham Offspring Study. (physiciansweekly.com)
  • Left atrial (LA) size, a marker of atrial structural remodeling, is associated with increased risk for atrial fibrillation (AF) and cardiovascular disease (CVD). (physiciansweekly.com)
  • In 1909, Welch (4) noted that cardiovascular stroke associated with AF was due to left atrial appendage (LAA) thrombi and that this was the most common site for thrombus formation in the setting of AF (5) . (onlinejacc.org)
  • It is well known that, as for most cardiovascular disorders, diabetes is an independent risk factor for atrial fibrillation (AF), and that the risk of AF is 1.4 to 2.1 times greater in patients with diabetes than the normal population [ 1 ]. (kjim.org)
  • Background- Changes in neurocognitive function after cardiopulmonary bypass (CPB) are difficult to assess in children with congenital cardiovascular malformations in part because identification of a suitable control group of children is difficult. (ahajournals.org)
  • recurrent
  • Prolonging atrial conduction time, as measured by tissue Doppler imaging (TDI), is an independent predictor of new onset or recurrent AF [ 3 , 4 ]. (kjim.org)
  • closure
  • Recently, Visconti et al 15 addressed some of these problems by performing a retrospective study in which a group of children who underwent closure of an atrial septal defect (ASD) by surgery were compared with another group of children who underwent ASD closure by a catheter-delivered device. (ahajournals.org)
  • congestive
  • Heart function improved by up to 25 percent in a trial using gene therapy to reverse cardiac damage from congestive heart failure in a large animal model, Mount Sinai researchers report. (mountsinai.org)
  • Correlations
  • FIMeanSeg also demonstrated significant negative correlations with total and contractile LA emptying functions (r=-0.25 and -0.27, P=0.04 and 0.02, respectively). (biomedcentral.com)
