Because in the myocardial ischemia cascade where LV diastolic dysfunction often precedes LV systolic dysfunction, the LA which fashions as an early marker of diastolic anomaly, could equally reflect a declining LV function and/or be a good predictor of potential sequelae. We assessed this association of LA function with reduced LV systolic function among hospitalized patients. Among patients with reduced LV ejection fraction, LA passive ejection fraction was lower (0.172 ± 0.12 vs. 0.232 ± 0.14, p = 0.013) whereas LA kinetic energy was higher (6.48 ± 6.3 vs. 4.57 ± 3.5, p = 0.005). Echocardiographic assessment of LA function, therefore, appears correlated with LVEF and could be important when risk stratifying hospitalized patients.展开更多

Many patients referred for surgery already have a poor clinical condition and an advanced New York Heart Association functional class. There is no consensus on the optimal surgical technique for this condition, including on whether to perform the procedure on a beating or an arrested heart and whether to perform valve repair or replacement. Methods: We analyzed four case series between 2015 and 2022 in which patients with secondary tricuspid regurgitation (TR) underwent valve repair on a beating heart and right atrial plication for a dilated right atrium. The TRI-SCORE was calculated for each patient. Results: All patients experienced a favorable postoperative course with significant improvements in heart failure symptoms. TR was markedly reduced;however, in one patient with concomitant mitral regurgitation (MR) and a high TRI-SCORE, MR worsened postoperatively. This patient later died from unknown causes due to multiple comorbidities in the late phase. Conclusions: Tricuspid valve repair on a beating heart was effective for improving the cardiac function, and the TRI-SCORE proved useful as a preoperative risk assessment tool. The underlying mechanism by which TR exacerbates MR requires further investigation.展开更多

Traditionally, assessment of left atrial function has been performed by measuring volumes with 2D echocardiography. Additionally, it can be assessed with transmitral Doppler and pulmonary vein Doppler. Recently, an alternative method has been incorporated, namely, measurement of myocardial deformation with color tissue Doppler-derived strain. However, this method has several limitations, such as suboptimal reproducibility, angle-dependence, signal artifacts and the fact that it only measures regional strain and does not obtain information about the curved portion of the atrial roof. To overcome these limitations in the quantification of atrial function, the use of speckle tracking echocardiography (STE) strain has been proposed. This technique is not derived from Doppler but rather from 2D echocardiography; it is angle-independent and allows one to measure global as well as regional atrial strain. In this editorial, we describe the physical and pathophysiological concepts of STE and underline the clinical usefulness of this new technique.展开更多

The Doppler myocardial performance index (MPI) may provide a method of assessing function in these patients. The purposes of this study were to evaluate the right ventricular function and its changes in patients with ASD after transcatheter closure of ASD. Methods MPI, defined as the sum of isovolumic relaxation time and isovolumic contraction time derived by ejection time, was measured from tricuspid inflow and right ventricular outflow;Doppler velocity profiles recorded during routine echocardiography.Twenty nine patients (13 men, 16 women;mean age 25.28±12.69, range 6 to 57 years) were diagnosed to secundum ASD [the stretched diameters of ASD were from 9 To 36 (24.91±7.98) mm], and had a successfully placed Amplatzer septal occluder (ASO) (the sizes of ASO were from 11 to 40 mm );there were 81 sex-matched, age-matched healthy people (control group 41men, 40 women;mean age 29.02 ± 14.22, range 4 to 45 years ). MPI was measured again on 3 days and 1 month after closure of ASD. Change in the study group was assessed and compared to the control subjects with structurally normal hearts. A complete 2-dimensional and Doppler echocardiographic examination was performed in all study groups. Results 1) The isovolumic relaxation and isovolumic contraction times [respectively(77.59 ± 14.39)ms vs (60.93 ±12.94)ms, P<0.0001;(28.28 ±10.88)ms vs (23.64 ±9.01)ms, P=0.027] were prolonged, and ejection time [(260.65 ±21.86 )ms vs (271.85 ± 21.92)ms, P=0.033] was shortened in patients with ASD compared with that in control subjects, resulting in a marked increase in the MPI(0.40 ± 0.07 vs 0.31 ± 0.05, P<0.0001) from normal values;2) by Pearson's correlations, the MPI had no correlation with heart rate and blood pressure in control subjects and patients with ASD, but it correlated positively with age in patients with ASD;3) by Pearson's correlations, the MPI correlated positively with the diameter of ASD and pulmonary artery pressure;4) after transcatheter closure of ASD, the MPI decreased markedly. Conclusions 1) MPI is a conceptually new, simple, and reproducible Doppler index in patients with ASD;2) MPI is free from the effect of age, heart rate and blood pressure;(3) MPI appears to be relatively dependent on changes in the diameter of ASD and pulmonary artery pressure;4) the right ventricular function was improved after transcatheter closure of ASD.(J Geriatr Cardiol 2007;4:220-224.)展开更多

Materials and Methods: This was an observational, single centre study conducted in India. A total of 50 patients who were admitted to department of cardiology from July, 2008 to February, 2009 with diagnosis of dilated cardiomyopathy and an ejection fraction of <40% were included. Results: Of the 50 patients, 34 (68%) were males. 27 (54%) patients were in NYHA class II and 23 (46%) patients were in NYHA class III. LA volume was found to be ≥40 ml in all patients. LV function and LA volume were found to be correlated (r = -0.789, p < 0.01). Similarly, there was a correlation between LV function and LA volume index (r = -0.826, p < 0.01). There was no correlation between LA volume index and duration of symptoms (r = 0.04). Conclusion: It can be concluded that there is a strong inverse correlation between LA volume and left ventricular function and also between LA volume index and left ventricular function. The patients with NYHA class III were having larger left atrial volume than those with NYHA class II. Moreover, the duration of symptoms has no correlation with left atrial volume index.展开更多

Methods: This is a prospective study evaluating patients who were referred to our CMR center for a clinical CMR. Left atrial function was obtained via Ve-CMR thru-plane images across the mitral valve after acquiring 2 perpendicular in-plane images as “scouts”. The atrial function and mitral inflow were quantified by computer analysis (Argus, Siemens). Atrial function was defined as atrial contraction (A-wave) volume divided by total inflow volume. Left atrial volumes were calculated via computer analysis. Mitral regurgitation and left ventricular ejection fractions were assessed visually. Results: Thirty-nine patients, with mean age 56 +/- 10 years, were enrolled. The mean left atrial function was 22.9% +/-14.5%;the range in left atrial function was 0% - 57%. There was a significant positive correlation between atrial function and increased left ventricular ejection fraction (r = 0.44, P < 0.01). There was a significant negative correlation between atrial function and severity of mitral regurgitation (r = -0.60, P < 0.01), as well as left atrial volume (r = -0.36, P = 0.02). Conclusion: Our results indicate a wide variability in left atrial function and a significant association between left atrial function and left ventricular ejection fraction, left atrial volume and mitral regurgitation.展开更多
