Abstract Introduction Acromegaly is a chronic, rare hormonal disease associated with major cardiovascular comorbidities. The disease, in the majority of the cases, is caused by a benign human growth hormone secreting adenoma. Cardiovascular involvement is especially common in acromegaly patients from the most common hypertension to cardiomyopathy. It was set out to quantify right atrial (RA) morphology and function in a group of acromegaly patients using three-dimensional (3D) speckle-tracking echocardiography (3DSTE). Methods The study comprised 30 patients from which 8 patients were excluded due to inadequate image quality. Mean age of the remaining acromegaly patients were 53.7 ± 14.5 years (7 males). Ten patients were in active phase, while 12 subjects had inactive acromegaly. In the control group 40 healthy adults were enrolled (mean age: 52.3 ± 8.2 years, 15 males). In each case, complete two-dimensional Doppler echocardiography was performed followed by 3DSTE. Results Maximum (54.5 ± 14.4 ml vs. 47.2 ± 11.6 ml, p <0.05) and minimum (35.5 ± 10.2 ml vs. 29.2 ± 9.1 ml, p <0.05) RA volumes and RA volume before atrial contraction (45.1 ± 11.1 ml vs. 38.2 ± 10.3 ml, p <0.05) were significantly higher in case of acromegaly compared to the healthy controls. Both global and mean segmental peak 3D strain (-11.94 ± 7.52% vs. -8.07 ± 5.03%, p <0.05 and -17.16 ± 6.13% vs. -13.78 ± 5.35%, p <0.05) were higher in the acromegaly group compared to the controls. At atrial contraction, mean segmental radial strain (-13.22 ± 6.45% vs. -9.74 ± 4.58%, p <0.05) was significantly higher and mean segmental 3D strain (-9.78 ± 5.44% vs. -13.78 ± 5.35%, p <0.05) was significantly lower in the acromegaly group compared to the controls. Between the active and inactive group of acromegaly patients, mean segmental longitudinal strain (28.17 ± 4.89% vs. 35.34 ± 9.75%, p <0.05) was significantly different. Numerous independent strain parameters had significant correlations with different hormonal variables in the active acromegaly group. These correlations were not present in the inactive acromegaly subgroup. Conclusion Acromegaly is associated with significant RA volumetric and functional abnormalities.

Abstract Introduction The right atrium (RA) has several roles including a systolic reservoir, early diastolic conduit and late-diastolic booster pump functions. The present study aimed to assess normal reference values of three-dimensional speckle-tracking echocardiography (3DSTE)-derived RA volumetric data and volume-based functional properties (stroke volumes, SVs and emptying fractions, EFs) in healthy adult subjects. Methods 260 healthy adult subjects in sinus rhythm with complete clinical and demographic dataset have been included in the present study. However, due to inferior image quality 110 subjects have been excluded. The remaining population comprised 150 cases (31.0 ± 11.6 years, 79 males). Complete two-dimensional Doppler echocardiography and 3DSTE have been performed in all subjects. Results While systolic maximum RA volume did not change over age decades, early and late-diastolic RA pre-atrial contraction volume and minimum RA volume increased over time. Significantly larger values could be detected in more than 50 year-old healthy subjects as compared to younger subjects. Total atrial SV remained almost unchanged over age decades with a significant reduction in subjects aged >50 years. Passive atrial SV showed a continuous reduction over age decades and significant difference could be demonstrated between subjects aged 18-29 years and >50 years. Active atrial SV increased over age decades with a significant reduction in subjects aged >50 years. Total atrial EF did not show any changes over age decades, but a significant reduction could be demonstrated in cases aged >50 years. Passive atrial EF showed significant continuous reduction over age decades. Active atrial EF did not change in younger ages, it was the highest at ages 40-49 years with a significant impairment after 50 years. Females proved to have tendentiously higher RA volumes respecting the cardiac cycle regardless of age. No significant differences could be demonstrated between RA stroke volumes between genders except between 40-49 years when females had tendentiously higher values. RA emptying fractions were non-significantly, but tendentiously higher in females as compared to that of males regardless of age. Conclusions Normal reference values of 3DSTE-derived RA volumes and volume-based functional properties and their age- and gender dependency were defined in healthy adult subjects.

Introduction: Left atrium is a heart chamber with dinamic motion communicating with left ventricle through the mitral valve and its annulus. Aim: The aim of the present study was to analyse whether relationships could exist between three-dimensional speckle-tracking echocardiography-derived morphologic and functional parameters of the left atrium and mitral annulus in healthy subjects. Method: The present study comprised 35 healthy volunteers. Maximum (Vmax) and minimum (Vmin) left atrial volumes and left atrial volume before atrial contraction (VpreA) were measured, and several functional parameters based on these volumes were calculated in all cases. Morphologic and functional characteristics of the mitral annulus were also determined. Results: While Vmax showed correlations with both systolic and diastolic mitral annulus parameters, Vmin-VpreA correlated with only systolic ones. While total left atrial stroke volume correlated with both systolic and diastolic mitral annular parameters, passive left atrial stroke volume showed correlations only with diastolic ones. Conclusions: Correlations exist between left atrial and mitral annular morphological and functional characteristics in healthy subjects. Orv. Hetil., 2014, 155(38), 1517–1523.
