  • appendage
  • 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)
  • significantly
  • The interatrial and left atrial electromechanical delay were significantly longer in prediabetic group compared to the controls. (kjim.org)
  • Left atrial active emptying volume (LAAEV) and fraction (LAAEF) were significantly higher in the prediabetics than the controls. (kjim.org)
  • During simultaneous V/A pacing at 160 beats/min, the reduction in end-diastolic and stroke volumes from the baseline value was -26.6 +/- 3.8 percent and -28.8 +/- 4.3 percent, respectively (both p less than 0.01), but was significantly smaller (-16.1 +/- 3.6 percent and -19.2 +/- 4.1 percent, respectively [p less than 0. when atrial transport was maintained during sequential A-V pacing at the same heart rate.

  • In sequential Cox proportional hazards models, A -wave, E / A ratio, and GLS were significantly associated with outcomes, independent of age, sex, and cardiac resynchronization therapy defibrillator or left bundle branch block. (edu.au)
  • LVEF
  • The aim of this study was to assess the association of the HF symptoms with LA function in patients with severe AS and preserved LVEF. (biomedsearch.com)
  • longitudinal strain
  • The global peak atrial longitudinal strain and strain rate of systolic LV (GLSs, GLSRs) as well as early and late diastolic LV strain rate (GLSRe, GLSRa) curves of LA were acquired in each LA segment from basal segment to top segment of LA by 2D-STE. (biomedcentral.com)
  • septal
  • In addition, the development of new interventional transcatheter procedures for AF, mitral valve repair, atrial septal defect closure, and LAA occlusion may result in intentional or unintentional instrumentation of the LAA. (onlinejacc.org)
  • sinus rhythm
  • Furthermore, this is the largest study to date demonstrating the survival advantage of sinus rhythm among patients with AF/Fl and left ventricular dysfunction. (acc.org)
  • Doppler
  • The prolongation of the intra-atrial and interatrial conduction time can be evaluated by simple electrocardiographic (ECG) markers such as maximum P wave duration (Pmax) and P wave dispersion (PWD) as well as by the tissue Doppler method [ 3 , 4 ]. (kjim.org)
  • 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)
  • acute
  • This study was conducted to assess the acute impact of Balloon Mitral Valvotomy (BMV) on these functions. (jcdronline.org)
  • Whether these acute changes translate into long term left atrial reverse remodelling and clinical benefits thereof needs to be established by further studies. (jcdronline.org)
  • patients
  • The aim of our study is to evaluate the LA function in patients with IDA by 2D-STE. (biomedcentral.com)
  • 2D-STE could evaluate the LA function in patients with IDA. (biomedcentral.com)
  • We assessed the hypothesis that strong lipophilic statin (pitavastatin) has a beneficial effect on LA structure and function in elderly hypertensive patients by preventing left ventricular (LV) hypertrophy through pleiotropic effect. (ahajournals.org)
  • In the prediabetic patients, the atrial conduction times and P wave dispersion on surface electrocardiographic were longer before the development of overt diabetes. (kjim.org)
  • Evaluate the effect of dronedarone versus placebo (standard therapy) in slowing the progression of adverse left atrial remodeling in patients with atrial fibrillation (AF) following 12 months of treatment. (clinicaltrials.gov)
  • We sought to determine the strongest variables that predispose the patients to have LA dilatation and impaired LA emptying function. (biomedcentral.com)
  • In the other 10 patients similar determinations were made during sequential A-V and simultaneous ventricular and atrial (V/A) pacing, both at rates of 100 and 160 beats/min. (ucl.ac.uk)
  • 0.02
  • 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)
  • fraction
  • LA function was estimated as the LA emptying fraction (LAEF), that is 100x (LAVmax-LAVmin)/LAVmax. (kb.se)
