Sachpekidis C, Sachpekidis V, Kopp-Schneider A, Arsos G, Moralidis E. Equilibrium radionuclide angiography: Intra- and inter-observer repeatability and reproducibility in the assessment of cardiac systolic and diastolic function. J Nucl Cardiol 2021; 28:1304-1314. [PMID: 31385225 DOI: 10.1007/s12350-019-01830-9] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2019] [Accepted: 07/16/2019] [Indexed: 10/26/2022]
Abstract
BACKGROUND This study aimed to assess intra- and inter-observer agreement in assessing the systolic and diastolic function with equilibrium radionuclide angiography (ERNA). MATERIALS AND METHODS Thirty-two adults underwent baseline and repeat ERNA. An experienced and a trainee operator analyzed the data by assigning regions of interest manually, fully automatically, and semi-automatically. The Bland-Altman statistic (mean ± 1.96 standard deviations of the differences) was used to assess the repeatability (two different assessments of a single acquisition) and reproducibility (assessments of two different acquisitions). RESULTS Using the semi-automated technique the intraobserver repeatability and reproducibility of left ventricular ejection fraction for the experienced physician were - 0.1 ± 3.7 and 0.0 ± 3.8 and for the trainee 2.2 ± 10.6 and 1.9 ± 8.4, respectively. The inter-observer repeatability and reproducibility were - 1.8 ± 6.4 and 0.4 ± 9.0, respectively. Among the parameters of diastolic function, the intraobserver repeatability and reproducibility of the peak filling rate for the experienced physician were - 0.0 ± 1.1 and - 0.1 ± 1.1 and for the trainee 0.2 ± 3.5 and 0.4 ± 3.7, respectively. The inter-observer repeatability and reproducibility were 0.3 ± 1.5 and 0.5 ± 4.0, respectively. Similar was the pattern for the other diastolic indices. In all cases the limits of agreement varied according to the quantification approach. CONCLUSION A good repeatability but a moderate reproducibility was found in the assessment of the LVEF. Less good were the findings in the assessment of diastolic function.

What is the most useful imaging parameter to explore the prognostic value of the right ventricular function at the time of multimodality cardiovascular imaging? Echocardiography 2020; 37:1233-1242. [PMID: 32686860 DOI: 10.1111/echo.14686] [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: 08/10/2019] [Revised: 12/28/2019] [Accepted: 04/21/2020] [Indexed: 11/28/2022] Open
Abstract
BACKGROUND Right ventricular (RV) function is a powerful independent predictor of adverse heart failure outcomes. The aim of this study was to compare the predictive value of main RV systolic imaging parameters for outcome. METHODS Seventy-nine patients underwent comprehensive cardiovascular imaging modalities including transthoracic echocardiography, cardiac magnetic resonance (CMR) imaging, and tomographic equilibrium radionuclide ventriculography (ERV) for the assessment of RV function. The composite primary endpoint (CPE) was defined by the occurrence of death, heart transplantation, implantation of a left ventricular assist device, or new-onset acute heart failure. RESULTS During a mean follow-up of 13 ± 9 months, 15 (19%) patients reached the CPE. The areas under the receiver operator characteristic curves for the prediction of the CPE were 0.922 (P < .001), 0.913 (P < .001), 0.906 (P < .001), 0.849 (P = .002), 0.837 (P = .003), 0.799 (P = .009), 0.792 (P = .011), 0.753 (P = .026), 0.720 (P = .053), and 0.608 (P = .346) for integral systolic S' wave tricuspid annular velocity, RV free wall longitudinal strain (RVFWLS), RV fractional area change, tricuspid annular plane systolic excursion, RV ejection fraction (RVEF) by CMR using the 4-chamber slices, peak systolic S' wave tricuspid annular velocity, RVEF by CMR using short-axis slices, RVEF by ERV, RV myocardial performance index, and RV myocardial acceleration during isovolumic contraction, respectively. CONCLUSION Echocardiographic parameters, and particularly integral systolic S' wave tricuspid annular velocity and RVFWLS, have the best prognostic performance.

Is TOMPOOL (gated blood-pool SPECT processing software) accurate to diagnose right and left ventricular dysfunction in a clinical setting? J Nucl Cardiol 2014; 21:1011-22. [PMID: 24875579 DOI: 10.1007/s12350-014-9915-3] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2014] [Accepted: 04/17/2014] [Indexed: 10/25/2022]
Abstract
BACKGROUND The assessment of right ventricular function is crucial for management of heart disease. TOMPOOL is a software that processes data acquired with Tomographic Equilibrium Radionuclide Ventriculography. In this report, TOMPOOL's diagnostic accuracy and inter-observer reproducibility were assessed in a cohort of patients with various etiologies of ventricular dysfunction. METHODS AND RESULTS End-diastolic volume (EDV), ejection fraction (EF), and cardiac output (CO) were calculated for the right ventricle (RV) and the left ventricle (LV) using TOMPOOL in 99 consecutive patients. Thirty-five patients underwent cardiac magnetic resonance imaging (CMR) considered as the reference-standard to measure EDV and EF; the Spearman's rho correlation coefficients were r = 0.73/0.80 and 0.67/0.73 for right/left EF and EDV, respectively. Twenty-one patients had thermodilution measurements of right CO (reference-standard), the correlation was r = 0.57. The best cut-off points (sensitivity/specificity) in order to diagnose a ventricular dysfunction or enlargement were 46% for RVEF (67%/89%), 62% for LVEF (100%/90%), 94 mL for RVEDV (77%/73%), and 84 mL for LVEDV (100%/91%). The areas under the ROC curve were, respectively, 0.79, 0.91, 0.83, and 0.99. Inter-observer reproducibility was r = 0.81/0.94, 0.77/0.90, and 0.78/0.75 for Right/Left EF, EDV, and CO, respectively. CONCLUSION TOMPOOL is accurate: measurements of EDV, EF, and CO are reproducible and correlate with CMR and thermodilution. However, thresholds must be adjusted.
