“…However, whether echocardiographic Mmode tracing of mitral annulus motion had relationships with NYHA functional class has not been clarified. The tissue tracking method using Doppler-tissue images (DTI) has been shown to accurately reflect myocardial velocity and displacement [15,16]. Furthermore, this technique provides us the degree of MAD after the aortic valve closure (AVC) as a marker of postsystolic thickening.…”

Objectives. The purpose of this study was to determine whether the assessment of mitral annulus displacement (MAD) using Doppler-tissue image (DTI) could provide a useful marker of heart failure severity.[Methods] In seventy-five subjects with heart diseases, we measured MAD by tissue-tracking method with DTI. MAD was evaluated in both septal and lateral corners of the mitral annulus in the apical 4-chamber view, and the degree of MAD in postsystolic phase was estimated as a ratio of displacement at aortic valve closure and peak point (P/A ratio).We divided subjects into three groups (group A: subjects with preserved MAD, group B: subjects with reduced MAD without increasing P/A ratio, group C: subjects with reduced MAD with increasing P/A ratio) and compared NYHA func- tional class and left ventricular ejection fraction (LVEF).Results. NYHA functional class and LVEF were significantly different among the three groups (NYHA functional class; group A: 1.2 0.4, group B: 2.3 0.9, group C: 3.1 0.8, LVEF; group A: 58 12 %, group B: 42 15 %, group C: 25 8 %). These results indicated that MAD which represents mainly LV longitudinal function is decreased in the first place, and then, post-systolic displacement is exaggerated according to the severity of heart failure.Conclusions. The classification of the degree and timing of peak MAD (P/A ratio) is well correlated with NYHA functional class and LVEF and becomes one of the useful indexes of heart failure severity.

The aim of this prospective study was to assess the value of speckle tracking echocardiographic (2D-STE) parameters to predict response to heart failure therapy in patients with dilated cardiomyopathy (DCM). Eighty-seven patients (mean age 51 ± 13 years) with DCM, defined as ejection fraction (EF) <45 %, left ventricular (LV) end-diastolic diameter >112 % of normal range derived from age and body surface area. Based on 2D-STE following parameters were extracted from three apical views of the LV: global longitudinal strain, systolic and diastolic strain rate (SRE). Mechanical dispersion was calculated as standard deviation of time-to-peak strain values including all LV segments. After receiving heart failure therapy (mean 39 ± 11 months, range 3-60 months) 50 patients reached combined endpoint defined as following: death, heart transplantation, rehospitalization due to heart failure, and absence of improvement in EF. On stepwise multivariate regression analysis, SRE was independently of EF and LV volumes predictive for combined endpoint (OR 0.44, 95 %CI 0.27-0.70, p = 0.001) with an area under the ROC-curve (AUC) of 0.91. In patients with cQRS duration ≤120 ms mechanical dispersion was predictive for combined endpoint with the highest AUC (OR 1.53, 95 %CI 1.08-2.16, p = 0.002; AUC = 0.94). In this study, SRE, a surrogate parameter of myocardial relaxation, was able to predict a response to heart failure therapy in patients with DCM. In patients with narrow QRS complex, mechanical dispersion yielded the highest predictive value. Parameters of 2D-STE may contribute to risk stratification in this patient population.
