“…The introduction of 3DE enables the accurate quantitation of RV volumes, function, and mass, and this accuracy can be compared with the results of MRI, which still remains a gold standard for the RV evaluation (31,32). Additionally, 2DE speckle tracking imaging, unlike conventional tissue Doppler imaging, identifies RV and RA myocardial deformation during the whole cardiac cycle, providing information not only about global strain but regional as well, and it also represents a highly reproducible imaging tool which could easily be used in everyday clinical practice (33).…”

Background: We sought to investigate right ventricular (RV) function and deformation assessed by three-dimensional echocardiography (3DE) and speckle tracking in patients with subclinical hypothyroidism (SHT), and to evaluate the influence of levothyroxine (L-T 4 ) therapy on RV remodeling. Methods: We included 50 untreated women with SHT and 45 healthy control women matched by age. The L-T 4 therapy was prescribed to all SHT patients who were followed 1 year after euthyroid status was achieved. All study participants underwent laboratory analyses which included thyroid hormone levels, and complete two-dimensional echocardiography (2DE) and 3DE examinations. Results: 3DE RV end-diastolic volume and ejection fraction were significantly reduced in the SHT patients before therapy in comparison with the healthy controls and treated SHT subjects. RV longitudinal strain, systolic, and early diastolic strain rates (SRs) were significantly decreased, whereas RV late diastolic SR was increased in the SHT patients before therapy when comparing with the controls. 2DE speckle tracking imaging revealed that L-T 4 substitution therapy significantly improved RV systolic mechanics, whereas RV diastolic deformation was not completely recovered. Right atrial (RA) function and deformation were significantly impacted by SHT. Replacement L-T 4 treatment improved but did not completely restore RA mechanics in the SHT patients. Conclusion: RV and RA function and mechanics are significantly affected by SHT. L-T 4 therapy and 1-year maintenance of euthyroid status improved but did not completely recover RV and RA function and deformation in the SHT patients, which implies that right heart remodeling caused by SHT is not reversible in a 1-year period.

“…Three-dimensional echocardiography allows the quantification of volumes and function in normal subjects and patients, 72 thereby allowing identification of patients with different degrees of severity of RV dilatation and dysfunction. 73 Several clinical studies have shown a good correlation between cardiac magnetic resonance and 3DE volumes and ejection fraction of the right ventricle in selected populations, with the majority of studies showing a slight underestimation of volumes compared with the reference technique.…”

“…Three-dimensional transthoracic echocardiography (3DTTE) has the advantage of full-volume acquisition of the entire right ventricle, which may overcome the technical and clinical limitations of 2-dimensional transthoracic echocardiography. [10][11][12] Recent studies have validated the accuracy of 3DTTE-determined RV volumes and RVEF against CMR 13,14 and determined the reference values of RV volumes and RVEF in healthy subjects. 15,16 However, the prognostic value of RVEF is largely unknown.…”

R ight ventricular (RV) function is closely coupled with subsequent morbidity and mortality in patients with diseases affecting the right heart chambers. [1][2][3][4][5][6][7] The most common cause of RV dysfunction is chronic left-sided heart failure. Complex factors such as pulmonary hypertension, intrinsic myocardial involvement, ventricular interdependence, and myocardial ischemia lead to RV dysfunction. 1 Therefore, assessment of RV function is clinically important in almost all patients with heart disease. However, the complex geometry of the RV poses a significant limitation to the reliable quantitation of RV volumes and ejection fraction (RVEF) using 2-dimensional transthoracic echocardiography. Although cardiac magnetic resonance (CMR) imaging is the gold standard for the evaluation of RV volumes and RVEF, 8,9 factors such as cost, portability, time consumption, and contraindications hinder its routine use in every patient. Three-dimensional transthoracic echocardiography (3DTTE) has the advantage of full-volume acquisition of the entire right ventricle, which may overcome the technical and clinical limitations of 2-dimensional transthoracic echocardiography. [10][11][12] Recent studies have validated the accuracy of 3DTTE-determined RV volumes and RVEF against CMR 13,14 and determined the reference values of RV volumes and RVEF in healthy subjects. 15,16 However, the prognostic value of RVEF is largely unknown. We hypothesized that RVEF assessed by 3DTTE (3DRVEF) would offer incremental value over left ventricular (LV) functional parameters for predicting future cardiac events. See Editorial by Fernández-Golfín and Zamorano See Clinical PerspectiveAccordingly, the aims of this study were (1) to validate the accuracy of 3DTTE-determined RV volumes and RVEF against CMR reference and (2) to evaluate the prognostic value of 3DRVEF to predict future cardiac death and major adverse cardiac events (MACEs) in a large number of patients.Background-Cardiac magnetic resonance is the gold standard for the evaluation of right ventricular (RV) volumes, but it is impractical to perform in every patient. Although reference values of RV volumes and RV ejection fraction by 3D transthoracic echocardiography (3DTTE) have been established, their prognostic values have not been elucidated yet. We hypothesized that RV ejection fraction measured by 3DTTE (3DRVEF) predicts future cardiovascular events. Methods and Results-In protocol 1, we determined the accuracy of RV volumes and RV ejection fraction measurements by 3DTTE against cardiac magnetic resonance in 60 subjects. In protocol 2, 3DRVEF was measured in 446 patients with various cardiovascular diseases. Study subjects were followed up to record cardiac death and major adverse cardiovascular events. In protocol 1, 3DTTE-determined RV end-diastolic volume, end-systolic volume, and RV ejection fraction had good correlations to those by cardiac magnetic resonance (r=0.74-0.90). In protocol 2, 38 cardiac deaths and 88 major adverse cardiovascular events occurred during a med...
