“…TAPSE assessed with CMR proved to be an unreliable measure of RV ejection fraction in patients with repaired TOF. These findings are in line with previous 3D echocardiographic studies which also demonstrated a weak correlation with RV ejection fraction and TAPSE [55]. The different observations made in other previous studies [42, 43] might be due to (1) the exclusion of the RV volume out of the plane in the 4-chamber view in case of 2D imaging, (2) the absence of tricuspid regurgitation, or (3) the presence of regional wall dysfunction.…”

Tetralogy of Fallot (TOF) is the most common cause of cyanotic congenital heart disease and is associated with a high prevalence of pulmonary regurgitation following repair often requiring later pulmonary valve replacement (PVR) [1][2][3][4][5][6][7][8][9][10][11][12][13]. Adults with repaired TOF and significant chronic pulmonary regurgitation are at risk for progressive right ventricular (RV) dilatation and dysfunction [14][15][16][17][18][19][20][21][22][23]. Helbing et al. [1] showed that impaired relaxation and restriction to filling affected RV function in patients with repair of TOF and pulmonary regurgitation. Uebing et al. [2] demonstrated that RV endsystolic volume is a useful measure for estimating RV function after TOF repair depicting parameters of systolic and diastolic RV function. Assessment of RV function is important in the management of these patients in particular when it comes to optimal timing of surgery for PVR. Timing of surgery must be carefully considered, weighing the up-front risks of surgery and possible repeat surgery against the risk of ongoing pulmonary regurgitation [24, 25]. Therefore, monitoring RV volume and function is useful for managing patients with TOF.Detailed and precise evaluation of RV function by cardiac imaging has been a long-standing challenge in clinical medicine. Two-dimensional (2D) imaging has been used to this purpose, but the complex shape of the RV has precluded accurate estimation of RV volume by 2D echocardiography using geometric models. Accordingly, all 2D echocardiographic methods show a rather poor performance in comparison with cardiovascular magnetic resonance imaging (CMR) [26]. Consequently, three-dimensional (3D) imaging methods combined with analysis using the multiple slice technique are more accurate because reliance on geometric modeling is eliminated. Over the past years, a vast experience had been built with CMR to investigate LV and RV dynamics [27][28][29][30][31][32][33][34][35][36][37][38][39][40][41]. As such, CMR has become the gold standard for quantitative analysis of RV anatomy, function, and shape [42][43][44][45][46][47]. Kayser et al. [48] evaluated the effect of throughplane motion on tricuspid flow measurements performed with CMR velocity mapping in nine normal subjects and 15 patients with RV disease.

“…Unlike left ventricle, myocardial fibers project longitudinally rather than 5 circumferentially in right ventricle, and TAPSE is used as a simple echocardiographic index of RV systolic function. Also, prior publications including ours have reported close correlations between TAPSE and RV EF [6][7][8][9]. However, few studies have focused on the ability of TAPSE for the mathematical prediction of RV EF.…”

Purpose: The present study examined whether tricuspid annular plane systolic excursion (TAPSE) can simply predict right ventricular ejection fraction (RVEF) in patients with pulmonary hypertension (PH). The TAPSE cut-off value to predict reduced RV EF was also evaluated. Methods and results:The association between TAPSE and cardiac magnetic resonance imaging (CMRI)-derived RVEF was examined in 53 PH patients. The accuracy of the prediction equation to calculate RVEF using TAPSE was also evaluated. In PH patients, TAPSE was strongly correlated with CMRI-derived RVEF in PH patients (r=0.86, p<0.0001). We then examined the accuracy of the two equations: the original regression equation (RVEF = 2.01 x TAPSE + 0.6) and the simplified prediction equation (RV EF = 2 x TAPSE). Bland-Altman plot showed that the mean difference ± limits of agreement was 0.0 ± 10.6 for the original equation and −0.6 ± 10.6 for the simplified equation. Intraclass correlation coefficient was 0.84 for the original and 0.82 for the simplified equation. Normal RV EF was considered to be ≥ 40% based on the data from 53 matched controls, and the best TAPSE cut-off value to determine reduced RV EF (< 40%) was calculated to be 19.7 mm (sensitivity 88.9%, specificity 84.6%). Conclusion:A simple equation of RV EF = 2 x TAPSE enables easy prediction of RV 3 EF using TAPSE, an easily measurable M-mode index of echocardiography. TAPSE of 19.7 mm predicts reduced RV EF in PH patients with clinically acceptable sensitivity and specificity.4

“…Many in vitro and in vivo studies have shown that RV volume and function can be quantified accurately by this approach. 3,7,8 However, the image quality of this method was comparatively poor because of relatively low spatial resolution. Furthermore, 3-D volumetric data was collected by integrating subvolume data, which was scanned during 4 consecutive heart beats.…”

“…4,13 More importantly, measurement of RV volume is made from sequential C-mode scan images and is based on adding multiple slice volumes. 3,7,8 Hence, 3-D volumetric method cannot be widely used for RV volume measurement in clinical practice because of the necessity of time-consuming off-line processes of endocardial tracing for multiple slices. More recently, a new generation real-time 3-D technique has simplified the process of 3-D data acquisition and 3-D RV volume analysis.…”

Background: Previous studies have demonstrated that 3-Dimensional (3-D) echocardiography can determine right ventricular (RV) volume accurately. However, this technique has not been feasible in everyday clinical practice because of the necessity of time-consuming off-line processes. Hypothesis: A newly developed real-time 3-D triplane echocardiography, which acquires 3 apical rotational cross-sectional images simultaneously, holds the promise to resolve these problems. Methods and Results: Sixteen excised formalin fixed porcine hearts and 24 healthy human subjects underwent real-time 3-D triplane echocardiography. In an anatomic in vitro study, the actual volume of RV was obtained by spilling water in the RV cavity into a graduated cylinder for measurement, which served as a reference standard for comparison. For healthy subjects, the RV stroke volume (SV) was measured by triplane echocardiography which was compared with the left ventricular (LV) SV obtained by conventional 2-Dimensional echocardiography (2-DE). Excellent correlation and agreement between 3-D triplane imaging derived RV volume and the actual one for excised porcine hearts were observed (r = 0.979, p<0.001, mean difference 2.2 mL). In healthy human subjects, good correlation and agreement between 3-D triplane imaging derived RV SV and LV SV measured by 2-DE were obtained (r = 0.970, p<0.001, mean difference 5.9 mL). Conclusions: Real-time 3-D triplane echocardiography provides us a new method for rapid and accurate quantification of RV volume. Furthermore, this new method holds the promise for evaluating RV volume and SV in routine clinical practice.Key words: echocardiography imaging, triplane imaging, right ventricle, volume Introduction Evaluation of right ventricle (RV) volume and function is quite important in a variety of cardiac disorders. 1 Measuring RV volume with conventional 2-Dimensional echocardiography (2-DE) has been difficult because of asymmetry and the complex geometry of RV. 2 Three-Dimensional (3-D) echocardiography does not require any assumption about chamber geometry, and thus is now regarded as an ideal method for quantifying RV volume and function. 3 -7 Many previous in vitro or in vivo studies have proved that 3-D echocardiography can determine RV volume accurately compared with the standard volume. 3 -8 However, this technique has not been feasible in everyday clinical practice because of the necessity of time-consuming off-line processes of endocardial tracing for multiple slices. A newly developed real-time 3-D triplane echocardiography, which acquires 3 apical rotational cross-sectional images simultaneously, holds the promise to resolve these problems. The aim of this study was to evaluate the capability of this new real-time 3-D triplane imaging technique for estimating RV volume in an anatomic in vitro model. Furthermore, the clinical feasibility of this technique for RV volume measurement was tested by comparing RV stroke volume (SV) to
