“…Most studies on 3D LAV have also reported on 3D maximum LAV (max LAV), 3D minimum LAV, and 3D pre-A LAV with their indexed values for LA function assessment. Generally, 3D LAV and LAVI showed similar trends to those for 2DE, namely that 3D max LAVIs were similar for both genders in spite of 3D max LAV for males being larger before indexation and not associated with age [26,31,32,55,57,58]. Some studies showed discrepant results.…”

“…Recently, the WASE Normal Values study used a uniformed measurement protocol to examine in two core laboratories data for over 2000 normal subjects enrolled worldwide, and found only minor differences for LV size among races and countries, although the normal reference values recommended in the current guidelines need to be adjusted [15]. Regarding 3DE, the current guidelines recommend normal values for 3D LV volumes on the basis of three studies published a decade ago [24][25][26], although several studies have reported that normal reference values for LV volumes were different in a variety of countries and regions [27][28][29][30][31][32] (Table 1). According to most of these publications, 3D LV volumes were larger than 2D LV volumes, as well as larger for males than for females even after indexing to BSA, while they decreased with age for both genders.…”

Echocardiography is used worldwide to evaluate cardiac size and function. To determine what values are abnormal, it is essential to establish normal reference values for echocardiography. The current guidelines for chamber quantification specify normative values for cardiac chambers and recommend that gender and body size be taken into account. However, these normative data were established using databases for which a variety of measurement methods were used and the majority of subjects consisted of Whites in Europe and the United States. However, several regional studies from other countries suggest that cardiac size varies globally. To overcome these limitations, the Normal Reference Ranges for Echocardiography study and the World Alliance of Societies of Echocardiography Normal Values study have recently been conducted to examine similarities and differences in cardiac chamber size and to establish normal reference values while taking worldwide diversity into account. The results from these studies have demonstrated that standardization of normal reference values for cardiac size is important. This review article aims to summarize the current status of normative echocardiographic values for cardiac chamber size.

Introduction: Hypopituitarism is a rare, often underdiagnosed, complex hormonal disease caused by the decreased secretion of one or more hormones in the pituitary gland. The present study was designed to assess left ventricular (LV) rotational mechanics in patients with treated hypopituitarism. It was also aimed to find possible differences in these parameters according to the origin of hypopituitarism (congenital vs. acquired).Methods: The present prospective study involved 35 treated patients with hypopituitarism; however, 4 patients had to be excluded due to inferior image quality. The mean age of the remaining 31 cases was 56.3 ± 13.2 years (18 males). The control group consisted of 29 age- and sex-matched healthy volunteers (mean age: 55.3 ± 4.8 years, 14 males). In all cases a complete two-dimensional echocardiography examination was performed followed by three-dimensional speckle-tracking echocardiography.Results: No significant differences could be found in LV volumes between the controls and patients with hypopituitarism and hypopituitary subgroups. LV apical rotation (8.1 ± 5.1° vs. 10.6 ± 3.5°, p < 0.05) and LV twist (11.9 ± 5.3° vs. 15.1 ± 3.8°, p < 0.05) were impaired in the hypopituitary group with normally directed LV rotational mechanics as compared to the healthy controls. However, 13% of patients showed a near absence of LV twist called LV “rigid body rotation” (LV-RBR). There were no significant differences regarding LV apical and basal rotations and twist between acquired and congenital hypopituitary subgroups.Conclusions: Impaired LV apical rotation and twist could be demonstrated in hypopituitarism regardless of its origin. In the present study with small number of patients with hypopituitarism, LV-RBR was present in 13% of cases.

Purpose: Patients with hypertrophic cardiomyopathy may exhibit impaired functional capacity, associated with increased morbidity and mortality. Systolic function is one of the determinants of functional capacity. Early identification of systolic disfunction may identify patients at risk for adverse outcomes. Myocardial deformation parameters, derived from three-dimensional (3D) speckle-tracking echocardiography (3DSTE) are are useful tools to assess left ventricular systolic function, and are often abnormal before a decline in ejection fraction is seen. The aim of this study was to evaluate the correlation between myocardial deformation parameters obtained by 3DSTE and functional capacity in patients with hypertrophic cardiomyopathy. Methods: Seventy-four hypertrophic cardiomyopathy adult patients were prospectively evaluated. All patients underwent a dedicated 2D and 3D echocardiographic examination and cardiopulmonary exercise testing (CPET). Results: Values of 3D global radial (GRS), longitudinal (3DGLS) and circumferential strain (GCS) were overall reduced in our population: 99% (n=73) of the patients had reduced GLS, 82% (n=61) had reduced GRS and all patients had reduced GCS obtain by 3DSTE. Average peak VO2 was 21.01 (6.08) ml/Kg/min; 58% (n=39) of the patients showed reduced exercise tolerance (predicted peak VO2< 80%). The average VE/VCO2 slope was 29.0 (5.3) and 16% (n= 11) of the patients had impaired ventilatory efficiency (VE/VCO2 >34). In multivariable analysis, 3D GLS (β1 = 0.10, 95%CI: 0.03;0.23, p=0.014), age (β1 = -0.15, 95%CI: -0.23; -0.05, p=0.002) and female gender (β1=-5.10, 95%CI: -7.7; -2.6, p<0.01) were independently associated with peak VO2. No association was found between left ventricle ejection fraction obtain and peak VO2 (r=0.161, p=0.5). Conclusion: Impaired myocardial deformation parameters evaluated by 3DSTE were associated with worse functional capacity assessed by peak VO2.
