“…The sample volume of PW Doppler was placed within the RAA and LAA septal and lateral walls. In the TDI records of the patients, a triphasic TDI profile was obtained in patients with sinus rhythm, and multiphasic fibrillatory emptying and filling velocities were recorded in AF patients, similar to previously described TDI velocities of LAA walls in the study of Parvathaneni et al [23]. The initial upward velocities in sinus rhythm (D1) were recorded early in diastole (before the P wave).…”

SummaryBackgroundThromboembolic risk in permanent atrial fibrillation (AF) is strongly associated with the underlying etiology, and inflammatory parameters may contribute. The present study aimed to investigate the relationship of hs-CRP and BNP levels with left and right atrial appendage (LAA and RAA) function, presence of spontaneous echo contrast (SEC) and thrombus.Material/MethodsEighty-four permanent AF patients with different etiologies (20 mitral stenosis, 44 hypertension and 20 hyperthyroidism) and 23 patients with sinus rhythm were included. LAA and RAA flow velocities were measured by pulsed-wave Doppler and wall motion velocities with tissue Doppler imaging (TDI) in transesophageal echocardiography.ResultsHs-CRP and BNP levels significantly differed among the 3 AF groups: levels were highest in mitral stenosis patients (8.6±5.3 mg/L and 98.0±125.7 pg/mL, respectively), the lowest hs-CRP was in hyperthyroidism patients (4.3±3.8 mg/L), and the lowest BNP was in hypertensive patients (64.8±44.3 pg/mL). There were also significant differences between the AF group and controls regarding hs-CRP and BNP levels. In the correlation analysis, BNP level was not significantly correlated with LAA and RAA functions, whereas hs-CRP level was significantly correlated with some LAA and RAA functions. On the other hand, hs-CRP level was significantly related to the presence of mild-moderate SEC and thrombi, mainly in mitral stenosis patients. Moreover, hs-CRP was the most important determinant of RAA thrombus formation, followed by RAA ejection fraction. In contrast, no positive or negative correlation was found between BNP levels and RAA and LAA thrombi.ConclusionsHigher hs-CRP levels in AF patients may be a predictor for the presence of SEC and thrombi in the atria.

“…The sample volume (4 mm) was placed at the proximal third of the medial and at the lateral sidewalls of the LAA. 16 LAA wall velocity was defined as the average of the peak upward velocity just before the QRS complex obtained from both the medial and lateral sidewalls of the LAA (Figure 2). LAA flow velocity and LAA wall velocity reflected active contraction of the LAA during SR or AF.…”

“…Previous studies also implicated that the modification of the AVD does not influence filling pattern in patients with normal ventricular function. 15,[20][21][22] In this study, we used LAAEV and LSV for evaluation of LAA function. 9,16,19 Both LA and LAA is potential site for development of thrombus.…”
