Abstract
To establish age-specific and body surface area (BSA)-specific reference values of Tricuspid Annular Plane Systolic Excursion (TAPSE) for children under 15 years old in China. A retrospective study was conducted in Children's Hospital Attached to the Capital Institute of Pediatrics. A total of 702 cases were included in this research to establish reference values of TAPSE in Chinese children. SPSS 25.0 (IBM) was used for data analysis. Lambda-mu-sigma method was used to calculate and construct the age-specific and BSA-specific percentiles and Z-score curves of TAPSE. The mean value of TAPSE increased with age and BSA from 0 to 15 years in a nonlinear way and reached the adult threshold (17 mm) until 1 year old. There was no difference between genders. TAPSE values increased with age and BSA in Chinese children aged between 0 and 15 years and there was no difference between boys and girls. A prospective, multicenter cohort study from different parts of China is supposed to be conducted in the future to reflect the whole spectrum of TAPSE in Chinese children.

Importance of Nonlongitudinal Motion Components in Right Ventricular Function: Three-Dimensional Echocardiographic Study in Healthy Volunteers. J Am Soc Echocardiogr 2020; 33:995-1005.e1. [PMID: 32620323 DOI: 10.1016/j.echo.2020.04.002] [Citation(s) in RCA: 40] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/07/2019] [Revised: 03/29/2020] [Accepted: 04/01/2020] [Indexed: 12/14/2022]
Abstract
BACKGROUND Global right ventricular (RV) function is determined by the interplay of different motion components related to the myofiber architecture, and the relative importance of these components is still not thoroughly characterized. The aims of this study were to quantify the relative contributions of longitudinal, radial, and anteroposterior motion components to global RV function and to examine their determining factors in a large cohort of healthy volunteers using three-dimensional echocardiography. METHODS Three hundred healthy adults with a balanced age range and an equal sex distribution were investigated at two centers. A three-dimensional mesh model of the right ventricle was generated, and its motion was decomposed along the three anatomically relevant axes. Multiplicative relative contributions were measured by dividing the ejection fraction (EF) values generated by shortening in the longitudinal, radial, and anteroposterior directions by global RV EF (longitudinal EF index [LEFi], radial EF index [REFi], and anteroposterior EF index, respectively). The circumferential contribution was defined as shortening in the radial and anteroposterior directions, omitting only longitudinal shortening. RESULTS Circumferential EF index was markedly higher compared with LEFi (79 ± 7% vs 47 ± 9%, P < .001). LEFi (47 ± 9%) and anteroposterior EF index (49 ± 7%) were found to be similar in the pooled population, whereas REFi (44 ± 10%) was lower (P < .001). In younger individuals (20-39 years of age), the relative contribution of longitudinal shortening was significantly higher compared with the radial component; however, in the older age groups, LEFi and REFi were comparable. Age, body surface area, heart rate, and RV end-diastolic volume were independent predictors of LEFi and REFi, but all with opposite effects on the two motion directions. CONCLUSIONS In contrast to the traditional viewpoint, the contributions of the radial and anteroposterior motion directions may be of comparable significance with that of longitudinal shortening in determining global RV function. Standard parameters referring only to longitudinal shortening of the right ventricle may be inadequate to characterize RV function thoroughly.

Abstract
BACKGROUND We had reported on the left ventricular end-diastolic dimension (LVDd) in normal children from the premature/neonatal period to the adolescence period by using two-dimensional echocardiography, and formulated equations to evaluate normal LVDd values by using body height as an index. There was an inflection point at around birth that seemed relevant to the fetal and neonatal periods for the relation of LVDd and body height. METHODS We aimed to reveal the true inflection point and its meaning by using change point regression analysis. The study group consisted of 421 neonates and infants. The ages at examination ranged from 24 weeks' gestation to 1 year after birth. The subjects' body heights at examination were between 31 and 75 cm. RESULTS The analysis showed no definite inflection point in height, and a flat bottom was observed between body heights of 48 and 55 cm. The inflection range seemed to mean the duration of the neonatal period, which connects the fetal and infantile periods. CONCLUSION The results revealed that neonates reach the infantile period slower than usually imagined, and the end of the neonatal period may be at the age when the body height is around 55 cm- in other words, at 2 months after birth. This manuscript might be the first one to consider the definition of the neonatal period using cardiovascular methods.

Abstract
BACKGROUND Reports of isolated tricuspid valve replacement (iTVR) are relatively rare. The present study aimed to evaluate independent risk factors of perioperative morbidity and mortality after iTVR. MATERIALS AND METHODS We retrospectively reviewed 118 consecutive patients (42 males; mean age, 49.1 ± 12.9 y) who underwent iTVR from May 2003 to April 2016 in our center. The multivariate logistic regression model was used to analyze the independent risk factors associated with perioperative morbidity and mortality following iTVR. RESULTS One hundred one patients (85.6%) were classified as New York Heart Association functional class III or IV preoperatively. The overall perioperative mortality was 11.8% (14/118), and a significant difference was observed between the nonreoperative group and the reoperative group (6.7% versus 18.3%, P = 0.047). The multivariate logistic regression analyses identified that preoperative New York Heart Association functional class IV (OR [odds ratio] = 15.43, 95% CI [confidence interval] = 3.46-68.83, P = 0.000) and ascites (OR = 4.88, 95% CI = 1.24-19.27, P = 0.024) were independent risk factors of perioperative deaths. The previous cardiac surgery (OR = 3.28, 95% CI = 1.41-7.62, P = 0.006) was independently associated with perioperative major adverse events. CONCLUSIONS The present study revealed that iTVR has relatively high mortality and morbidity rates. Timely surgery may be recommended for this high-risk cohort of patients before the development of severe heart and end-organ failure.

Quantification of the relative contribution of the different right ventricular wall motion components to right ventricular ejection fraction: the ReVISION method. Cardiovasc Ultrasound 2017; 15:8.

Abstract
Three major mechanisms contribute to right ventricular (RV) pump function: (i) shortening of the longitudinal axis with traction of the tricuspid annulus towards the apex; (ii) inward movement of the RV free wall; (iii) bulging of the interventricular septum into the RV and stretching the free wall over the septum. The relative contribution of the aforementioned mechanisms to RV pump function may change in different pathological conditions. Our aim was to develop a custom method to separately assess the extent of longitudinal, radial and anteroposterior displacement of the RV walls and to quantify their relative contribution to global RV ejection fraction using 3D data sets obtained by echocardiography. Accordingly, we decomposed the movement of the exported RV beutel wall in a vertex based manner. The volumes of the beutels accounting for the RV wall motion in only one direction (either longitudinal, radial, or anteroposterior) were calculated at each time frame using the signed tetrahedron method. Then, the relative contribution of the RV wall motion along the three different directions to global RV ejection fraction was calculated either as the ratio of the given direction’s ejection fraction to global ejection fraction and as the frame-by-frame RV volume change (∆V/∆t) along the three motion directions. The ReVISION (Right VentrIcular Separate wall motIon quantificatiON) method may contribute to a better understanding of the pathophysiology of RV mechanical adaptations to different loading conditions and diseases.

Abstract
It is not always easy to observe and screen atrial septal defects (ASD) using echocardiography. In addition, there are no established echocardiographic reference indices for screening patients with ASDs. We retrospectively reviewed our database and recruited 151 isolated ASD patients and 2769 healthy subjects. In total, 307 echocardiographic studies were performed for ASD patients. Surgical repairs were done in 75 of the ASD patients. The ratio of right to left ventricular end-diastolic dimensions (RVD/LVD), which was determined by M-mode echocardiography, was used as an index of RV dilatation. After obtaining age- and body surface area (BSA)-related RVD/LVD nomograms in healthy subjects, we calculated the z-scores of RVD/LVD for all subjects and obtained the optimal cut-off values to differentiate patients with ASD from healthy subjects. The optimal cut-off values were high in neonates and gradually decreased with an increase in the age and BSA, but were almost constant in children aged >4 years or whose BSA was >0.65 m(2). The cut-off values of RVD/LVD for suspected ASD were ≥0.42 in children aged >4 years or those whose BSA was >0.65 m(2). Those for an ASD operation were ≥0.46 in those whose BSA > 0.65 m(2). The RVD/LVD determined by M-mode echocardiography is a useful index to evaluate RV dilatation in patients with ASDs. The RVD/LVD ≥ 0.42 is the warning flag for suspecting ASD in preschool children and that ≥0.46 may be a clinical important sign to determine ASD operation.

Abstract
Aim of our study was to evaluate right ventricular (RV) systolic function in neonate using newly developed single-beat three-dimensional echocardiography (sb3DE). We enrolled 15 healthy or premature neonates (0-53 days after birth). We scanned one beat full volume using Siemens ACUSON SC2000 (Siemens AG) echocardiography with 4Z1c full-volume transducer without ECG gating. RV end-diastolic volume (RVEDV) and RV end-systolic volume (RVESV) were computed with special software dedicated to analysis for RV volume. RV ejection fraction (RVEF) and RV stroke volume (3D-RVSV) were calculated. And RV stroke volume was also determined from the recordings of ejection blood flow velocity and diameter at the level of the pulmonary orifice in RV outflow tract (Doppler-RVSV). Tricuspid annular plane systolic excursion (TAPSE) was also measured by 2D echocardiography. RVEDV ranged from 5.1 to 10.7 ml (average 7.5 ml), RVESV ranged from 2.3 to 5.8 ml (average 3.9 ml). There was a good correlation between 3D-RVSV and Doppler-RVSV (r = 0.77). Bland-Altman plot revealed that 3D-RVSV became underestimation of an average of 1.78 ml compared to Doppler-RVSV. And TAPSE positively correlated with 3D-RVEF (r = 0.58, P = 0.038). Newly developed sb3DE enables us to perform three-dimensional acquisition of RV volume without ECG gating even in neonate. However, 3D-RVSV currently tends to be underestimated in neonatal measurement.

Impairment of Left Ventricular Longitudinal Contraction is Associated with Serum Brain Natriuretic Peptide Concentration in Patients with Acute-Phase Kawasaki Disease. Pediatr Cardiol 2015; 36:979-86.

Abstract
It is well known that brain natriuretic peptide (BNP) is elevated in the acute phase of Kawasaki disease (KD). We hypothesized that mitral annular plane systolic excursion (MAPSE) could identify LV dysfunction in the acute phase of KD. Fifty patients with KD were enrolled in this study. BNP sampling and an echocardiographic study were performed just before and after intravenous immunoglobulin administration. MAPSE was measured in M-mode in the apical four-chamber view. The %MAPSE was calculated as the MAPSE measured in the acute phase divided by that measured in the convalescent phase. We compared the acute and the convalescent phases of KD. The values of the MAPSE were significantly reduced (45 out of 50 patients) during the acute phase and immediately recovered in the convalescent phase (10.0 ± 1.9 vs. 12.7 ± 1.9 mm, P < 0.0001). Of the parameters tested, %MAPSE was the only echocardiographic parameter that was associated with Log-BNP. Additionally, %MAPSE had a significant negative correlation with Log-BNP (r = -0.45, P < 0.0039). Longitudinal LV contraction is impaired in the acute phase of KD, but it immediately recovers in the convalescent phase. Measuring the longitudinal LV contractility should be essential for evaluating LV function in the acute phase of KD, and MAPSE is useful for this evaluation.
