Cardiovasc Ther 2023; 2023:1552826. [PMID: 37496726 PMCID: PMC10368509 DOI: 10.1155/2023/1552826] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/07/2022] [Revised: 05/25/2023] [Accepted: 06/06/2023] [Indexed: 07/28/2023] Open
Abstract
Over the last two decades, the changing paradigm of heart failure with preserved ejection fraction (HFpEF) has transformed our understanding not only of the pathophysiology of this clinical entity but also the diagnostic and therapeutic approaches aimed at treating this complex patient population. No longer HFpEF should be seen as simply left ventricular diastolic dysfunction but as a group of that in addition of having small and thick left ventricles with abnormal diastolic filling patterns as their main pathophysiologic abnormality; they also have whole host of different abnormalities. In fact, this heterogeneous clinical entity embodies numerous mechanisms and is linked to multiorgan dysfunction, with hypertension and obesity playing a major role. Although we have gained an enormous amount of understanding not only on the causes but also the downstream effects of HFpEF, there is still much to be learned before we can fully comprehend this complex clinical entity. It is the main intention of this review to synthesize the most recent attributes, mechanism, diagnostic tools, and most useful therapeutic alternatives to be considered when evaluating patients either complaining of dyspnea on exertion as well as exercise intolerance or those recently admitted with HF symptoms but with normal LVEF in the absence of any other valvular abnormalities.

Utility of the tricuspid annular tissue doppler systolic velocity and pulmonary artery systolic pressure relationship in right ventricular systolic function assessment: A pilot study. Echocardiography 2022; 39:1276-1283. [PMID: 36100955 DOI: 10.1111/echo.15441] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2022] [Revised: 07/15/2022] [Accepted: 08/09/2022] [Indexed: 12/01/2022] Open
Abstract
BACKGROUND Tricuspid annular plane systolic excursion (TAPSE) to pulmonary artery systolic pressure (PASP) ratio has been validated as a valuable noninvasive measure of right ventricular (RV) elastance and systolic function. However, the more reliable TA systolic (s') velocity measure of RV systolic function compared to TAPSE has not been previously studied. METHODS We conducted a pilot study using several variables of RV function in 50 patients with the main aim to determine which numerical expression between TA TDI s'/PASP and TAPSE/PASP ratio was most useful. RESULTS In a stepwise multiple regression analysis, TA TDI s'/PASP ratio (p < .0002); LVOT VTI/RVOT VTI ratio (p < .0002); RVOT VTI (p < .0047); TAPSE/PASP ratio (p < .0259) and TA TDI e' (p < .0292) were best in discriminating normal versus abnormal RV systolic function. Using receiver operator curve analysis, cut-off values for both TA TDI s'/PASP (>3.9 mm/c/mmHg) had 82.1% sensitivity and 77.3% specificity while the TAPSE/PASP (>.61 mm/mmHg) had 89.3% sensitivity and 68.2% specificity in identifying normal RV function in our studied population. CONCLUSION Our results indicate that TA TDI s'/PASP is a better mathematical expression when examining the relationship between RV contractility and RV resistance relationship. Furthermore, we also found that inclusion of RVOT VTI, RV diastolic properties, and left ventricular systolic function are important determinants of RV systolic function assessments and should be routinely included. Additional prospective studies are now needed to confirm these results using hemodynamic data.

López-Candales A, Vallurupalli S. Right ventricular free wall contractility in subcostal views: A proof-of-concept study to assess right ventricular systolic function. Echocardiography 2021; 38:2052-2059. [PMID: 34847245 DOI: 10.1111/echo.15258] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2021] [Revised: 09/03/2021] [Accepted: 11/05/2021] [Indexed: 11/29/2022] Open
Abstract
BACKGROUND Normal right ventricular (RV) function has been traditionally assessed from the apical window. However, in several patients the subcostal window is the only available acoustic. METHODS Given the intricate functional and mechanical inter-dependence between longitudinal tricuspid annular (TA) displacement and RV free wall contractility (RVFW), we studied the utility of RVFW inward motion using both M-mode and velocity with tissue Doppler imaging (TDI) from the subcostal transthoracic view. RESULTS If a TAPSE value ≥ 2 cm is used to identify normal RV function, an RVFW M-mode value > .8 cm, TA TDI s' velocity > .06 cm/s and TA TDI e' velocity value > .05 cm/s identify normal RV systolic function. Furthermore, ROC curve analysis for the RVFW M-mode showed an area under the curve (AUC) of .753 (95% CI: .604-.868) with a cut-off value > .8, sensitivity 75% and specificity 73%; for TA TDI s' AUC at .822 (95% CI: .681-.919) with a cut-off value > .06, sensitivity 75% and specificity 77% and for TA TDI e' the AUC was .771 (95% CI: .624-.882) with a cut-off value > .05, sensitivity 90% and specificity 46%. Reproducibility of repeat RVFW M-mode, TDI s' and e' measurements was good with strong inter-rater agreement (Kappa > .8). CONCLUSIONS The subcostal window appears useful for assessing RV systolic function. Additional studies are now required to prospectively use these measures in the routine evaluation of RV systolic function particularly in patients with suboptimal apical windows.

Abstract
BACKGROUND Speckle-tracking echocardiography (STE) has provided a reliable means to enhance characterization and quantification of global right ventricular (RV) systolic function. The use of Automated Functional Imaging (AFI) software has been previously used to quantify RV longitudinal peak global strain (PGS) values during two-dimensional (2D) transthoracic echocardiographic examinations. However, there is a paucity of data regarding relative strain contribution of each individual regional segments when compared with global strain assessment. Consequently, our goal was to use AFI STE to examine the strain contribution of each regional segment when assessing RV function. METHODS A retrospective analysis was performed on 107 patients that met our study criteria to correlate 2D TTE measures of RV systolic function to both RV AFI STE longitudinal peak global strain (PGS) and each individual regional RV free wall (RVFw) and inter-ventricular septum (IS) strain values. RESULTS We found that TTE variables of RV systolic function only correlated with PGS (RVFAC; P < .0001, TAPSE; P < .0001, and TA TDI S'; P < .0001) but none of the six individual regional AFI strain values. When PGS was not included in the multivariate analysis, only the mid RVFw and mid IS strain regions correlated with measures of RV systolic function. CONCLUSIONS Regional differences do exist with regards to strain generation along the RVFw and IS. These differences could be physiologically and anatomically explained based on our current understanding of RV muscle fiber arrangement. Further research is now needed to better characterize RV function in different clinical entities.

Abstract
Introduction reduced exercise capacity, coronary artery abnormalities and reversible myocardial ischemia have been demonstrated after arterial switch operation (ASO) and coronary reimplantation. Despite this, indices of systolic function, assessed by standard and Doppler echocardiography, are within the normal range. The aim of this study was to highlight the long-term changes in myocardial function following coronary reimplantation using Doppler and speckle-tracking imaging (STI) echocardiography. Methods this observational case control study included 36 patients and 20 gender and age-matched healthy controls. A group study was performed using patients who were followed for at least 6 months after the operation and who visited the pediatric cardiology outpatient between October 2015 and May 2016. Systolic and diastolic parameters, left ventricle (LV) and right ventricle (RV) myocardial performance were assessed in each group. Results the LV global peak strain parameters revealed a significant decrease in the longitudinal and circumferential strain components. The LV global longitudinal strain (GLS) values were lower in both groups of operated patients than controls (-19.9 ± 2.2% (group 1) versus -20.9 ± 1.6% (group 2) versus -22.9 ± 2.3% (group 3), p<0.001). The patients with coronary reimplantation had the lowest values. The LV global circumferential strain was also decreased in the group 1 patients as compared with the 2 other groups (-16.6 ± 4.1% (group 1) versus -19.4 ± 3.9% (group 2) versus -19.8 ± 4.0% (group 3), p<0.001). Conclusion although global LV function, assessed with conventional echocardiographic parameters, was normal, the 2D-STI analysis showed slight but significant decrease in the global and segmental longitudinal and circumferential LV strain during the long-term follow-up after coronary arteries reimplantation.

Abstract
Background Mitral annular plane systolic excursion (MAPSE) is a well-known surrogate measurement of left ventricular ejection fraction (LVEF) and prognostic factor for many cardiac conditions. However, little is known about its role in assessing LV diastolic function; we therefore sought to identify potential determinants of MAPSE in patients with LV diastolic dysfunction (LVDD). Methods Our echocardiographic database was queried for studies of patients with normal sinus. Patients were allocated into three groups: LVDD 0, LVDD 1 and LVDD 2 in accordance with LVDD stages recommended by the American Society of Echocardiography guidelines. Results A total of 107 echocardiographic studies were included in the study. The mean MAPSE was 1.22 ± 0.32 cm. Groups LVDD 0 (n = 23), LVDD 1 (n = 43), and LVDD 2 (n = 41) were significantly different in most of the studied variables. Particularly, MAPSE differed between the three groups (P < 0.01). A multiple regression analysis showed that age, LVEF and LV mass index were predictors of MAPSE instead of LVDD and left atrial measurements. Finally, a regression model was constructed to predict MAPSE in the studied group showing that age and LVEF explained a 46% of the MAPSE variation. A two-way contour plot was illustrated to ease the model interpretation. Conclusions Age and measures of LV systolic function correlated well with MAPSE. A simplified model to predict MAPSE based on age and LVEF is proposed. Additional studies are needed to examine the potential role of MAPSE in identifying symptoms and overall prognosis in LVDD patients.

Abstract
Introduction In this study, we assessed the adequacy of the two echocardiographic parameters representing the longitudinal systolic function of the ventricles, MAPSE & TAPSE, in perioperative monitoring. Aims 1. The assessment of MAPSE and TAPSE during the early (4 weeks) postoperative period after surgical correction of congenital heart defects in infants, performed with CPB. 2. The verification of the hypothesis, that the significant decline of TAPSE observed in this period is not related to the global RV systolic dysfunction. For this reason, systolic function of the RV was additionally assessed with another echocardiographic parameter: RVFAC. Material and methods Prospective study with 51 infants operated due to ASDII, VSD, AVSD and TOF. Four measurements of MAPSE,TAPSE and RVFAC were performed in the apical four-chamber projection. TAPSE and MAPSE were expressed as metric values and z-score; RV FAC values were expressed in percentages. Results TAPSE uniformly declined in the first postoperative day down to 34.5% of the initial value (p <0.00001), then gradually increased: up to 42.9% and 52% respectively, remaining significantly lower than preoperatively (p <0.001). RV FAC: increased by 21% (p <0.01), then remained stable in consecutive examinations. MAPSE declined by 21% during the first postoperative day, but with promptly normalized completely. Conclusions The movement of both AV valve annuli is subjected to different, not fully understood influences. The relatively slight decline of MAPSE makes this parameter suitable for the assessment of the postoperative LV systolic function. Deep, long-lasting decline of TAPSE, uniform in the whole group, does not permit to use this parameter and suggests the choice of another one, e.g. RVFAC.

Is mitral annular ascent useful in studying left ventricular function through left atrio-ventricular interactions? Indian Heart J 2018; 70:368-372.

Abstract
Background The mitral annulus (MA) is a crucial structure that is in constant motion throughout the cardiac cycle. The main purpose of this study was to determine if M-mode evaluation of the longitudinal motion of the MA could be useful to examine atrio-ventricular interactions. Methods Echocardiographic data obtained from 150 patients (mean age 56 ± 16; 82 males) from the University of Cincinnati College of Medicine was evaluated to examine if any relationship exists between MA motion and measures of atrio-ventricular interactions. Results Even though left atrial size, left ventricular (LV) mass index, LV ejection fraction (LVEF) and degree of LV diastolic dysfunction (LVDD) were significant echocardiographic variables affecting MA motion; LVEF and the degree of LVDD were the main determinants of MA excursion during systole (MAPSE) and after atrial contraction (MAa). Our results confirm the surrogate value of MAPSE with regards to LVEF and also show that the extent of MA excursion during systole is the main determinant of MAa. The effect of LV diastolic function applies more strongly to MAPSE than to MAa. However, the maximal MAa amplitude varies in accordance to the type of LVDD. Conclusions We have shown for the first time that M-mode interrogation of the MA longitudinal motion appears useful to assess atrio-ventricular interactions. Since LV systolic and diastolic functions are so closely related; additional studies are now required to examine how this longitudinal measure correlates with known circumferential rotational data obtained with other imaging modalities.

Abstract
BACKGROUND Even though left atrial (LA) size and function are intimately related to left ventricular (LV) diastolic dysfunction, the role of LA with regard to LV systolic function is less clear. Consequently, we examined the potential association that might exist between measures of longitudinal LV systolic shortening and LA dilation using LA volume index (LAVI). METHODS In this retrospective analysis, data from 75 echocardiograms (mean age 53 ± 14; range 24 - 89 years; mean body surface area (BSA) 2.0 ± 0.3) were analyzed. RESULTS Peak global longitudinal (PGLS) correlated best with LV mass index (LVMI) followed by mitral annular systolic excursion (MAPSE), and age. Similar results were obtained when analyzing the best variables that correlated with LAVI. Finally, MAPSE correlated best with PGLS, then with MA tissue Doppler systolic velocity, BSA, and LAVI in that order. All patients had normal LV ejection fraction (LVEF) and normal sinus rhythm when studied. CONCLUSIONS LAVI does not directly affect LV systolic function and longitudinal measures of LV shortening are mainly dependent on LV mass. Additional studies are now required to determine how these associations vary when different degrees of LV dilatation and systolic dysfunction are included in the analysis.

Abstract
BACKGROUND Even though the tricuspid annulus (TA) is anatomically and functionally related to right atrioventricular dependence and tricuspid annular plane systolic excursion (TAPSE) is a well-known measure of right ventricular (RV) systolic function, there is paucity of data regarding the potential impact that right atrial (RA) size and function have on TAPSE. Hence, we sought to determine whether RA volumetric and longitudinal measures affect TAPSE in patients with chronic pulmonary hypertension (cPH). METHODS In this retrospective study, echocardiographic data from 110 patients were reviewed and the studied population was divided into Group I consisting of 50 patients (50±11 years) without PH and Group II that included 60 patients (55±14 years) with cPH. RESULTS Even though RA areas, RA fractional area change, and maximal long-axis length measurements were abnormal in cPH patients, TA tissue Doppler imaging systolic velocity and RV fractional area change were the only useful variables in identifying patients with abnormal TAPSE (P<.0001 and P=.018, respectively). Additionally, TAPSE was independent of all RA measures, left ventricular ejection fraction, and age (P>.05). CONCLUSIONS Based on these results, TAPSE does not appear to be influenced by either RA size or function. Additional studies using strain echocardiography to interrogate RA mechanics might now be very useful to advance our understanding of TA motion in cPH patients given recent data showing that RA function accounts for a significantly greater proportion of total right heart function in patients with cPH than in normal subjects.

Abstract
To evaluate the right ventricular (RV) function in relation to that of the left ventricle (LV) in patients with dilated cardiomyopathy (DCM). Echocardiographic examination was done using tissue Doppler imaging (TDI) and two-dimensional speckle tracking echocardiography (2D-STE) for 32 pediatric patients with DCM comparing them to another 32 normal matched controls. The global longitudinal strain (GLS) derived from 2D-STE was used to reflect the LV systolic function. Tricuspid annular plan systolic excursion (TAPSE) and the following RV TDI derived indexes: peak systolic velocity (S'), peak early diastolic velocity E', peak late diastolic velocity A', isovolumic acceleration (IVA) and myocardial performance index (MPI) were measured. RV had significant systolic and diastolic dysfunction; TAPSE, S' velocity, IVA, peak early diastolic velocity (E') and peak early diastolic velocity/peak late diastolic velocity (E'/A') ratio were significantly decreased while MPI was significantly prolonged compared to controls. Moreover, TAPSE, S', IVA, E', E'/A' and RV MPI were significantly correlated to LV GLS. For prediction of LV dysfunction among patients, the area under the receiver operating characteristic curve was 0.98 for RV MPI, 0.906 for RV IVA. For identifying severe LV dysfunction; RV MPI > 0.29 had 100% sensitivity and 93.7% specificity, while the RV IVA ≤ 3 had 84.4% sensitivity and 90.6% specificity. In pediatric patients with DCM the RV systolic and diastolic functions are affected beside the LV dysfunction. Non-conventional echocardiographic evaluation of RV function is recommended in among this cohort.

Abstract
BACKGROUND Pulmonary arterial hypertension (PAH) is known to trigger right ventricular (RV) remodeling that might compromise left ventricular (LV) filling due to inter-ventricular interdependence. In this study, we aimed to examine standard echocardiographic measurements of LV diastolic function in PAH patients. METHODS In this retrospective study, we identified clinical as well as complete echocardiographic data from 128 chronic PAH patients to fully assess LV diastolic dysfunction (LVDD) using standard recommended Doppler guidelines. Accordingly, patients were divided into three groups: LVDD 0, LVDD 1 and LVDD 2. RESULTS The mean age of the studied population was 57 ± 14 years with a mean pulmonary artery systolic pressure (PASP) of 55 ± 21 mm Hg. A total of 36% of the study patients had normal LV diastolic function. However, 64% had LVDD with LVDD stage 1 being the most common (48%). In terms of echocardiographic data, significant differences were found among the three LVDD groups in regards to PASP, LV end systolic and diastolic volumes, tricuspid annular plane systolic excursion, right ventricular fractional area change as well as many other tissue Doppler imaging parameters. Finally, just age and PASP were predictors of abnormal LV diastolic function (P < 0.05). CONCLUSIONS Impaired relaxation is a common abnormality in PAH patients. Additional studies are warranted to determine whether LVDD alters prognosis or is related to changes in the symptomatic profile of this group of patients.

Abstract
Introduction There is scarce information about right ventricle (RV) function in patients with secondary pulmonary hypertension (PH) undergoing transcatheter aortic valve implantation (TAVI). We aim to identify possible RV abnormalities in patients referred for TAVI with severe aortic stenosis (sAS) and secondary PH. Methods Objective measures of RV function, as well as noninvasive estimates of pulmonary artery systolic pressures (PASP) were obtained from 30 sAS patients undergoing percutaneous valve intervention. Results Sixteen (53%) evaluated patients had some degree of PH. As expected, left ventricular mass index (281 ± 75 g/m2) and left atrial volume index (89 ± 23 mL/m2) values were significantly elevated. Even though RV end-systolic (8 ± 4 cm2) and end-diastolic (17 ± 4 cm2) areas were normal as well as RV fractional area change values (57 ± 16%); both longitudinal measures of RV systolic function such as tricuspid annular plane systolic excursion (1.9 ± 0.5 cm) and systolic velocity (10 ± 2 cm/s) were clearly reduced with just mild elevations in PASP (54 ± 7 mmHg). Conclusions Subclinical RV dysfunction is present in patients with sAS and secondary PH undergoing TAVI. Whether longitudinal measures of RV systolic function could predict clinical outcomes in these patients needs to be further explored.

Abstract
Background. While the mitral annular plane systolic excursion (MAPSE) has been suggested as a surrogate measurement of left ventricular ejection fraction, less is known about the relative value of mitral annular ascent (MAa). Methods. Our database was queried for complete transthoracic echocardiograms performed for any clinical indication. Baseline echocardiographic measurements were compared to determine any correlation between MAa and traditional Echo-Doppler echocardiographic measures to characterize left ventricular diastolic dysfunction (LVDD). Results. Patients with normal LV diastolic function were younger (41 ± 13 years) than patients with LVDD (stage 1: 61 ± 13 years; stage 2: 57 ± 14 years; and stage 3: 66 ± 17 years; p = 0.156). LV ejection fraction decreased in patients with stage 2 LVDD (63 ± 17%) and was further reduced in patients with stage 3 LVDD (28 ± 21; p = 0.003). Discussion. While a vigorous MAa excursion was seen in patients with stage 1 LVDD, MAa significantly decreased in stage 2 and stage 3 LVDD patients. Our results highlight the importance of atrioventricular coupling, as MAa motion seems to reflect changes in left atrial pressure. Additional studies are now required to better examine atrioventricular interactions and electromechanical coupling that might improve our assessment of LV diastolic function.

Abstract
The aim of this study was to determine the effect of induction dose of anthracycline chemotherapy on the biventricular function among children with acute hematological malignancies (AHM) using tissue Doppler imaging (TDI) and 2D speckle tracking echocardiography (2D-STE). Thirty pediatric patients with AHM and a mean age of 9.24 ± 4.14 years performed conventional echocardiography, TDI and 2D-STE. After induction chemotherapy, the RV showed mainly a diastolic alteration in its function manifested in significant reduction in the tricuspid TDI-derived E' and E'/A' ratio compared with the baseline (20.40 ± 3.81 vs. 17.47 ± 3.87 cm/s, p = 0.001, 1.29 ± 0.27 vs. 1.03 ± 0.37, p < 0.01, respectively), while the TDI-derived RV MPI and isovolumetric relaxation time of RV were significantly increased (0.32 ± 0.06 vs. 0.36 ± 0.08, p < 0.01, 24.73 ± 8.62 vs. 28.47 ± 11.51 ms, p < 0.05, respectively). The LV showed post-chemotherapy mainly an alteration in its longitudinal systolic function in the form of a reduction in MAPSE (13.61 ± 2.00 vs. 11.95 ± 1.75 mm; p < 0.001), TDI-derived systolic velocity of lateral mitral annulus (10.98 ± 2.34 vs. 10.03 ± 1.83 cm/s, p < 0.05), 2D-STE-derived global longitudinal strain (-21.58 ± 2.54 vs. -19.18 ± 3.59 %, p = 0.001) and 2D-STE-derived global longitudinal strain rate (-1.76 ± 0.22 vs. 1.55 ± 0.29 1/s, p < 0.05), with preservation of LV diastolic function when compared to baseline. TDI and 2D-STE could be used for early detection of anthracycline-induced cardiotoxicity in the pediatric age group. Early after induction chemotherapy, the RV develops mainly diastolic dysfunction, while the LV showed a relative longitudinal systolic impairment.

Abstract
Background: A growing body of evidence suggests that the presence of a right bundle branch block (RBBB) is a negative prognostic indicator in patients with and without preexisting heart disease. Even though electromechanical activation of the right ventricle (RV) in patients with RBBB and pulmonary hypertension (PH) has been investigated; a direct comparison of the presence of RBBB, on the duration of RV mechanical systole using echocardiography has not been studied. Materials and Methods: In this retrospective study, we analyzed the echocardiograms of 40 patients by measuring the magnitude and timing of tricuspid annulus plane systolic excursion (TAPSE) and tricuspid annulus systolic velocity (TA S’). Patients were selected to form four groups of ten patients based on the presence or absence of RBBB and PH to determine if RBBB has any effect on the time-to-peak of TAPSE or TA S’, which for our purposes serves as a measure of duration of RV mechanical systole. Results: Our results demonstrate that RBBB leads to a measurable prolongation of TAPSE and TA S’ in patients without PH. Time-to-peak of TAPSE or TA S’ was not significantly prolonged in patients with PH. Conclusions: The results of this pilot study show that RV mechanical systole is prolonged in patients with RBBB, and the addition of PH attenuates this change. Additional prospective studies are now required to elucidate further the electrical and mechanical dyssynchrony that occurs as a result of RBBB, and how these new echocardiographic measurements can be applied clinically to risk stratify patients with RBBB and PH.

Abstract
Prompt and accurate diagnosis of patients presenting with symptoms suggestive of pulmonary arterial hypertension (PAH) is of outmost importance as delays in identifying this clinical entity have detrimental effects on both morbidity and mortality. Initial noninvasive assessment of these patients has traditionally included a number of routine tests of which transthoracic echocardiography (TTE) has been shown to either confirm the presence of structural anomalies of the right ventricle (RV) indicative of PAH or exclude other potential causes of pulmonary hypertension (PH). Consequently, TTE has become a well-validated and readily available imaging tool not only used for this initial screening but also for routine follow-up of PH patients. Since chronic PH is known to unbalance the normal hemodynamic and mechanical homeostatic interaction between the RV and pulmonary circulation; the resulting response is that of an abnormal RV remodeling, clinically translated into progressive RV hypertrophy and dilatation. An enlarged and hypertrophied RV not only would eventually lose effective contractility but also this gradual decline in RV systolic function is the main abnormality in determining adverse clinical outcomes. Therefore, it is of outmost importance that TTE examination be comprehensive but most importantly accurate and reproducible. This review aims to highlight the most important objective measures that can be routinely employed, without added complexity, that will certainly enhance the interpretation and advance our understanding of the hemodynamic and mechanical abnormalities that PH exerts on the RV.

Abstract
BACKGROUND Right atrial (RA) enlargement has been associated with worse clinical outcomes in chronic pulmonary hypertension (cPH) patients. Even though current guidelines only recommend measurement of RA dimensions at the end of ventricular systole in these patients, there is paucity of information regarding the potential utility of RA dimensions obtained at the end of ventricular diastole. METHODS In this retrospective study, standard echocardiographic data were collected from 80 studies. The population studied was divided into Group I that consisted of 35 patients (52 ± 10 years) without PH while Group II included 45 patients (56 ± 14 years; P = 0.2) with cPH. RA measurements were obtained not only at the end of ventricular systole, but also at the end of ventricular diastole to determine which RA measurement was more indicative of abnormal right ventricular afterload. RESULTS Even though all RA measurements were abnormal, RA area (>8.4 cm(2) ) measured at the end of ventricular diastole was the most useful RA variable to identify cPH patients with elevated pulmonary pressures (P < 0.0001) and with an abnormal pulmonary vascular resistance (P = 0.001). CONCLUSIONS Based on these results, it appears that isolated RA measurements made at the end of ventricular systole are insufficient to fully explain the hemodynamic load of cPH. Additional studies are now required to determine whether sequential monitoring of the composite change in RA dimensions that occur throughout the cardiac cycle over time correlates better with response to vasodilator therapy and overall clinical outcomes.

Abstract
We aimed to evaluate the aortic elastic properties in subjects with hypertensive response to exercise stress test (HRE). Sixty-six patients were divided into two groups (33 patients in HRE group and 33 patients in normotensive group). Baseline demographic characteristics were similar. The mean aortic stiffness index (ASI) was significantly higher (p=0.001) whereas aortic distensibility (AD) was significantly lower (p=0.029) in patients suggesting HRE. The C-reactive protein levels of patients with HRE was higher in the HRE group (p=0.03). AD was significantly correlated with age (r=-0.406, p<0.001), pre-test systolic blood presure (SBP) (r=-0.427, p<0.001), peak exercise SBP (r=-0.307, p=0.01), peak exercise diastolic blood presure (DBP) (r=-0.315, p=0.008), and recovery time (3 min) SBP (r=-0.497, p=0.004). Age (β=-0.506, p=0.003) and peak DBP (β=-0.322, p=0.049) were independent predictors of decreased AD. In conclusion, we found a deterioration in arterial elastic properties in patients with HRE.

Abstract
Objective: Left ventricular (LV) dysfunction after trastuzumab treatment in erb-2 breast cancer cases has been fully investigated. However, there is not enough data about the effect of trastuzumab treatment on right ventricular (RV) functions. This study is designed to evaluate the right heart changes by performing echocardiography after trastuzumab treatment in patients with erb-2 breast cancer. Methods: Forty-two consecutive breast cancer patients with erb-2 overexpression mean age 50.4±11.6 years who were decided to receive trastuzumab treatment were enrolled. Echocardiographic examinations including 2-D, spectral, and tissue Doppler measurements were performed at the baseline (T1) and repeated after 6 months (T2). Results: Tricuspid annular plane systolic excursion (TAPSE) was decreased, RV myocardial performance index (RVMPI) and tricuspid E/e’ ratio was increased after trastuzumab treatment (1.84 vs. 2.14; p<0.01) (0.46 vs. 0.56, p<0.01) (4.4±1.07 vs. 5.08±1.46; p=0.04). Median serum NT-ProBNP levels, troponin I, and hs-CRP levels were similar between the groups. LVEF and TAPSE were negatively correlated with dosage of trastuzumab (r=-0.392, p=0.04; r=-0.522, p=0.006). There was a stepwise decrease in LVEF when trastuzumab used with anthracyclines however this not reached statically significant (62.4±2, 60±4.5; p=0.06). Conclusion: In our study; we observed a trend of RV deterioration after trastuzumab treatment. These preliminary RV changes were demonstrated by using TAPSE, RV tissue Doppler imaging derived MPI and E/e’ ratio parameters by echocardiography and these parameters could also use as markers of trastuzumab toxicity in this population.

Abstract
PURPOSE This study was designed to show the relationship between tricuspid annular plane systolic excursion (TAPSE) and stroke volume (SV) by thermodilution using three different methods and also to assess whether TAPSE can track hemodynamic changes associated with volume loading and ephedrine administration. METHODS This was an observational study in 61 elective patients with a pulmonary artery catheter who were undergoing coronary artery bypass graft surgery in a cardiac surgical centre. We measured TAPSE by three methods using transesophageal echocardiography: M mode, speckle tracking at the lateral wall, and tissue tracking at the inferior wall. There were two interventions: leg raising (volume recruitment) or administration of ephedrine 5 mg iv. Echo and hemodynamic measurements were performed before and after each intervention. RESULTS Eleven patients were excluded due to poor imaging. There were 26 patients in the leg raising group and 24 patients in the ephedrine group. The correlation coefficient between stroke volume (SV) and TAPSE by M mode, speckle tracking, and tissue tracking was 0.48, 0.44, and 0.09, respectively. There was a significant increase in SV following each intervention; however, the changes in TAPSE by any method and velocity were not large enough to reach statistical significance. CONCLUSION Tricuspid annular plane systolic excursion by M mode and by speckle tracking correlates modestly with SV. There was no correlation between TAPSE and SV by tissue tracking at the inferior wall of the right ventricle. Tricuspid annular plane systolic excursion by M mode and by speckle tracking does not track changes in SV following either volume loading or ephedrine administration.

Abstract
The mitral annulus plays an important role in leaflet coaptation, in unloading mitral valve closing forces, and in promoting left atrial and left ventricular filling and emptying. Perturbations of annular mechanics figure prominently in a number of disorders including functional and ischemic mitral regurgitation, mitral valve prolapse, atrial fibrillation, mitral annular calcification, and annular submitral aneurysm. This review discusses the role of annular dysfunction in the pathogenesis of these disorders.

Abstract
Right ventricular (RV) function impacts the outcome in cardiac and pulmonary diseases such as heart failure, pulmonary hypertension, myocardial infarction, valvular, and congenital heart diseases. To our knowledge, simultaneous evaluation of left ventricular (LV) and RV systolic and diastolic echocardiographic indices in outpatients with clinically stable cardiovascular diseases has never been performed. Thus, we designed a prospective cohort study to define the prognostic power of these parameters. One hundred and sixty-three patients were submitted to transthoracic echocardiography with multiparametric and tissue Doppler evaluation of the following indices: ejection fraction, MAPSE, TAPSE, RV presystolic peak, LV and RV diastolic function, pulmonary artery systolic pressure, and functional mitral regurgitation. All these parameters and clinical variables (age, sex, and prior cardiovascular events) were entered in a multivariable Cox regression model. The primary end point was the occurrence of major cardiovascular events (MACEs) during the follow-up period. Twenty-one MACEs were observed; in the final multivariable Cox regression model only prior cardiovascular events (B 1.305, p 0.004, 95% CI 1.523-8.933), age (B 0.067, p 0.005, 95% CI 1.020-1.121), and TAPSE (B -1.065, p 0.026, 95% CI 0.135-0.883) were associated with MACEs. TAPSE, a simple and reproducible echocardiographic index, may be viewed as an early echocardiographic marker of heart involvement in atherosclerosis. We believe that TAPSE may be useful in clinical practice for risk stratification.

Abstract
BACKGROUND Tissue Doppler imaging (TDI) of mitral (MA) and tricuspid annular (TA) events has been shown to describe systolic and diastolic properties of each respective ventricle. However, the effect of chronic elevations in pulmonary artery systolic pressure (PASP) on individual diastolic annular velocities has not been well characterized. METHODS Measurements of left (LV) and right ventricular (RV) performance and TDI of the lateral MA and TA to measure systolic and early and late diastolic velocities were recorded from 50 individuals (group I: mean age was 56 ± 15 years and mean PASP of 29 ± 6 mm Hg) and from 50 patients (group II: mean age was 55 ± 14 years and mean PASP of 83 ± 27 mm Hg). RESULTS Group II patients had worse parameters of RV performance whereas LV systolic function remained unaffected when compared with group I. Group II had lower TA early velocities (0.09 ± 0.04 m/sec versus 0.12 ± 0.03 m/sec; P < 0.0001) with higher late diastolic MA velocities (0.12 ± 0.04 m/sec versus 0.10 ± 0.03 m/sec; P < 0.002) than group I. MA late diastolic velocity (P < 0.02) was the most useful in identifying elevated PASP and early diastolic TA velocity (P < 0.01) in identifying abnormal right ventricular fractional area change. CONCLUSION Chronic pulmonary hypertension seems to selectively affect TDI annular diastolic velocities of both ventricles in different ways. Additional studies are needed to correlate changes in annular TDI velocities with symptoms and clinical outcomes in chronic pulmonary hypertension.

Abstract
OBJECTIVES The optimal repair of functional mitral regurgitation is still debated. No device is able to simultaneously abolish mitral regurgitation and replicate natural mitral annular dynamics. We have tested a fully elastic mitral ring in an acute animal study with the purpose of evaluating (1) ring design and implantation technique, (2) elastic performance, and (3) acute effects on the native mitral annulus. METHODS Ten healthy sheep underwent surgical implantation of mitral devices, the elastic component of which is represented by a helicoid metallic spring. Preimplantation and postimplantation echocardiographic parameter measurements to evaluate annular dynamics and ventricular function comprise mitral annular motion, systolic tissue Doppler imaging peak wave, transmitral pressure gradient, peak transmitral flow velocity, and ejection fraction. Postimplantation angiographic analysis allowed measurement of the mitral annular area and perimeter variations by means of segmentation of the radiopaque mitral device contour. RESULTS No significant difference in terms of ejection fraction (P = .13) and systolic tissue Doppler imaging peak wave (P = .87) was found before and after implantation. Mitral annular motion (1.16 cm) was preserved. The percentage of systolic annular reduction derived from angiographic analysis was 14.1% (range, 7.7%-19.7%) in terms of area and 7.2% (range, 4.9%-10.0%) in terms of perimeter. CONCLUSIONS A mitral elastic ring, implantable by using a standard technique, acutely preserves mitral annular dynamics, allowing area and perimeter changes. Further chronic study is needed to verify the biocompatibility and durability of the device.
