“…Quantitative analysis of mitral annular dynamics with the use of TDE has been reported to provide reliable measurements that satisfactorily correlate with the gold standard indexes of global systolic and diastolic per-formance in disease states. [11][12][13] Tissue Doppler interrogation of the tricuspid annulus was validated as a method for evaluating RV functions in several recent studies. Peak systolic and late diastolic tricuspid annular velocities were demonstrated to have a positive and negative correlation with the ejection fraction and right atrial pressure, respectively.…”

SUMMARYControversy exists about the influence of patient age on the benefit of surgery in atrial septal defect (ASD). Tissue Doppler echocardiography (TDE) when applied to atrioventricular annuli provides variables reliably reflecting the performance of the corresponding ventricle. We sought to investigate the effect of timing of surgery on biventricular functions by comparing the conventional echocardiography variables and TDE profiles of right and left atrioventricular annuli in patients treated at various ages. Conventional echocardiography and TDE analysis of mitral and tricuspid annuli were performed in 20 controls and 61 patients who underwent surgical ASD closure 2.8 ± 2.5 years before the study. Standard parameters included were right and left-sided dimensions, estimated pulmonary artery pressure, ejection fraction, and tricuspid annular motion amplitude. TDE variables were systolic, early and late diastolic peak velocities at tricuspid lateral-and mitral-annulus at lateral and septal corners. Two subsets of patients who underwent surgery before (group 1, n = 20) and after 25 years (group 2, n = 41) formed our subgroups. Peak systolic TDE velocity and tricuspid annular motion amplitude had the lowest value in group 2 (P < 0.01 and <0.02, respectively). Late diastolic TDE velocity was significantly lower in group 2 compared to group 1 (P < 0.05). Increased right ventricular and atrial dimensions (P < 0.001 for both) and the estimated pulmonary artery pressure (P < 0.03) were the conventional measurements discriminating group 2 from group 1. The TDE profile of the mitral annulus was similar between the groups. These results suggest that delayed ASD closure is a relatively less effective procedure to restore secondary right ventricular dysfunction, as demonstrated by significantly different TDE measurements reflecting right ventricular longitudinal contraction and relaxation.

In general, pump function and myocardial contractility should be assessed when evaluating left ventricular (LV) systolic function. Ejection fraction obtained from left ventriculography is routinely used as an index of pump function, and the maximum value of the first derivative of LV pressure curve (peak dP/dt) has been used as an index of myocardial contractility. On the other hand, active relaxation of the LV myocardium during early diastole and LV passive filling or compliance during mid-to late diastole are important factors in evaluating LV diastolic function. To obtain this information, the time constant of the LV pressure decay during isovolumic diastole (tau) and LV end-diastolic pressure, which are calculated from the LV pressure curve recorded during cardiac catheterization, is used. However, invasive hemodynamic measurements cannot be performed in all patients, nor are they appropriate for follow-up evaluation involving repeated examinations.Recently, routine echocardiography has facilitated the noninvasive evaluation of LV systolic and diastolic function. The percent fractional shortening of the LV based on M-mode echocardiography and the LV ejection fraction determined by two-dimensional echocardiography are indices of LV pump function, and therefore cannot accurately evaluate LV myocardial contractility. On the other hand, "diastology" has become an important clinical topic [1]. There are several reasons why assessment of diastolic function is important: 1) 30 to 40% of patients evaluated for congestive heart failure have normal LV pump function [2,3]; 2) the transmitral flow velocity pattern, which is recorded using the pulsed Doppler method, may be an index for noninvasive evaluation of LV diastolic function [4]; and 3) the prognosis is poor in patients with LV systolic dysfunction and pseudonormalization or restrictive pattern of the transmitral flow velocity [5,6]. However, it has been shown that the diastolic indices obtained from transmitral and pulmonary venous flow velocities are influenced by loading conditions, especially by the pre- The Role of Tissue Doppler Imaging as a New Diagnostic Option in Evaluating Left AbstractThe widespread use of the pulsed Doppler echocardiography has facilitated the noninvasive evaluation of hemodynamic abnormalities of the left atrium and left ventricle (LV) based on transmitral and pulmonary venous flow velocity patterns. However, it has been shown that loading conditions, especially preload, influence the indices obtained from these velocity patterns. Recently, tissue Doppler imaging (TDI) has been applied to the clinical setting to assess LV myocardial function. In particular, this procedure has the following characteristics: 1) it can provide circumferential and longitudinal information for the LV myocardium; 2) the early diastolic LV myocardial parameters determined by TDI are not influenced by preload; 3) LV myocardial contractility can be evaluated from the early systolic parameters; 4) LV systolic and diastolic asynchrony can be detected; 5) myoca...

The ability to derive non-invasively information on left ventricular diastolic function on one hand and pressure gradients on the other hand, makes Doppler ultrasound a very attractive tool in clinical practice. However, the limitations of the standard Doppler approaches in differentiating between normal and pseudonormal filling patterns, together with the limitations of the simplified Bernoulli equation for assessing pressure gradients, are well described. In this manuscript the role of colour M-mode Doppler echocardiography as a tool that can overcome these limitations is discussed. Relevant key concepts of the haemodynamics of left ventricular filling and its relationship with colour M-mode Doppler echocardiography are introduced.
