Three-Dimensional Echocardiography for Transcatheter Aortic Valve Replacement Sizing: A Systematic Review and Meta-Analysis.

ABSTRACT: Background Transcatheter aortic valve replacement (TAVR) is the standard of care for many patients with severe symptomatic aortic stenosis and relies on accurate sizing of the aortic annulus. It has been suggested that 3-dimensional transesophageal echocardiography (3D TEE) may be used instead of multidetector computed tomography (MDCT) for TAVR planning. This systematic review and meta-analysis compared 3D TEE and MDCT for pre-TAVR measurements. Methods and Results A systematic literature search was performed. The primary outcome was the correlation coefficient between 3D TEE- and MDCT-measured annular area. Secondary outcomes were correlation coefficients for mean annular diameter, annular perimeter, and left ventricular outflow tract area; interobserver and intraobserver agreements; mean differences between 3D TEE and MDCT measurements; and pooled sensitivities, specificities, and receiver operating characteristic area under curve values of 3D TEE and MDCT for discriminating post-TAVR paravalvular aortic regurgitation. A random effects model was used. Meta-regression and leave-one-out analysis for the primary outcome were performed. Nineteen studies with a total of 1599 patients were included. Correlations between 3D TEE and MDCT annular area, annular perimeter, annular diameter, and left ventricular outflow tract area measurements were strong (0.86 [95% CI, 0.80-0.90]; 0.89 [CI, 0.82-0.93]; 0.80 [CI, 0.70-0.87]; and 0.78 [CI, 0.61-0.88], respectively). Mean differences between 3D TEE and MDCT between measurements were small and nonsignificant. Interobserver and intraobserver agreement and discriminatory abilities for paravalvular aortic regurgitation were good for both 3D TEE and MDCT. Conclusions For pre-TAVR planning, 3D TEE is comparable to MDCT. In patients with renal dysfunction, 3D TEE may be potentially advantageous for TAVR measurements because of the lack of contrast exposure.

Project description:(1) Background: We performed this study to evaluate the agreement between novel automated software of three-dimensional transesophageal echocardiography (3D-TEE) and multidetector computed tomography (MDCT) for aortic annular measurements of preprocedural transcatheter aortic valve replacement (TAVR); (2) Methods: PubMed, EMBASE, Web of Science, and Cochrane Library (Wiley) databases were systematically searched for studies that compared 3D-TEE and MDCT as the reference standard for aortic annular measurement of the following parameters: annular area, annular perimeter, area derived-diameter, perimeter derived-diameter, maximum and minimum diameter. Meta-analytic methods were utilized to determine the pooled correlations and mean differences between 3D-TEE and MDCT. Heterogeneity and publication bias were also assessed. Meta-regression analyses were performed based on the potential factors affecting the correlation of aortic annular area; (3) Results: A total of 889 patients from 10 studies were included in the meta-analysis. Pooled correlation coefficients between 3D-TEE and MDCT of annulus area, perimeter, area derived-diameter, perimeter derived-diameter, maximum and minimum diameter measurements were strong 0.89 (95% CI: 0.84-0.92), 0.88 (95% CI: 0.83-0.92), 0.87 (95% CI: 0.77-0.93), 0.87 (95% CI: 0.77-0.93), 0.79 (95% CI: 0.64-0.87), and 0.75 (95% CI: 0.61-0.84) (Overall p < 0.0001), respectively. Pooled mean differences between 3D-TEE and MDCT of annulus area, perimeter, area derived-diameter, perimeter derived-diameter, maximum and minimum diameter measurements were -20.01 mm2 ((95% CI: -35.37 to -0.64), p = 0.011), -2.31 mm ((95% CI: -3.31 to -1.31), p < 0.0001), -0.22 mm ((95% CI: -0.73 to 0.29), p = 0.40), -0.47 mm ((95% CI: -1.06 to 0.12), p = 0.12), -1.36 mm ((95% CI: -2.43 to -0.30), p = 0.012), and 0.31 mm ((95% CI: -0.15 to 0.77), p = 0.18), respectively. There were no statistically significant associations with the baseline patient characteristics of sex, age, left ventricular ejection fraction, mean transaortic gradient, and aortic valve area to the correlation between 3D-TEE and MDCT for aortic annular area sizing; (4) Conclusions: The present study implies that 3D-TEE using novel software tools, automatically analysis, is feasible to MDCT for annulus sizing in clinical practice.

Project description:BackgroundOur goal was to determine the accuracy of 3-dimensional transesophageal echocardiography (3D-TEE) compared with that of computed tomography (CT) in the preoperative evaluation for transcatheter aortic valve replacement (TAVR) when the errors caused by inconsistent software and method have been eliminated and the representativeness of the sample has been improved. We also investigated the influence of aortic root calcification on the accuracy of 3D-TEE in aortic annulus evaluations.MethodsPart I: 45 of 233 patients who underwent TAVR in the department of cardiovascular surgery at the Xijing hospital from January 2016 to August 2019 were studied retrospectively. Materialise Mimics software and the multiplanar reconstruction method were used for evaluation, based on 3D-TEE and CT. The annulus area-derived diameter, the annulus perimeter-derived diameter (Dp), the annulus mean diameter, the left ventricular outflow tract Dp diameter, the sinotubular junction (STJ) diameter-Dp, and the aortic sinus diameter were compared and analyzed. Part II: 31 of 233 patients whose 3D-TEE and CT data were well preserved and in the required format were included. HU450 and HU850 were used as indicators to measure the severity of calcification. The Spearman rank correlation and Linear regression were used to analyze the correlation between aortic root calcification and the accuracy of 3D-TEE in aortic annulus measurement.ResultsThe measurement results based on 3D-TEE were significantly lower than those obtained using CT (P < 0.05), except for the STJ diameter-Dp in diastole (P = 0.11). The correlation coefficient of the two groups was 0.699-0.954 (P < 0.01), which also indicated a significant correlation between the two groups. A Bland-Altman plot showed that the ordinate values were mostly within the 95% consistency limit; the consistency of the two groups was good. By establishing the linear regression equation, the two groups can be inferred from each other. The Spearman rank correlation analysis and the Linear regression analysis showed that the influence of aortic calcification on the accuracy of the 3D-TEE annulus evaluation was limited.ConclusionsAlthough an evaluation based on 3D-TEE underestimated the results, we can deduce CT results from 3D-TEE because the two methods exhibit considerable correlation and consistency.Trial registrationName: Surgery and Transcatheter Intervention for Structural Heart Diseases.
