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 Background Studies on pediatric heart transplantation (HTx) are uniquely challenging because pediatric HTx center volumes are generally low. And, the biventricular function plays an important role in the prognosis of pediatric HTx. The primary aim of our study was to evaluate biventricular function of pediatric HTx by three-dimensional speckle tracking echocardiography(3D-STE). Methods We enrolled 30 clinically well pediatric HTx patients and 30 sex- and age- matched healthy controls. All subjects underwent comprehensive echocardiographic examinations. Left ventricular (LV) global longitudinal strain (GLS), global circumferential strain (GCS), LV and right ventricular (RV) ejection fraction (EF) and RV longitudinal strain (RVLS) of free wall and septum were acquired by 3D-STE. And the correlations between strains and clinical data were explored. Results Compared with controls, LV GLS was decreased in pediatric HTx patients (P<0.05), while LV GCS and LVEF showed no difference. RVEF, RVLS (free wall) and RVLS (septum) in HTx group were diminished (P<0.05), but RVEF was still in normal range. Cold ischemic time was correlated inversely with LV GLS (β=-0.401, P<0.05). The mean pulmonary artery pressure (β=0.447, P<0.05) and postoperative tricuspid regurgitation pressure (β=0.607, P<0.05) were associated with RVLS (free wall). Conclusion Biventricular longitudinal systolic function rather than global systolic function was impaired after HTx. 3D STE may be able to evaluate the ventricular function better. Prolonged ischemic time leads to impaired LV longitudinal systolic function in pediatric HTx patients. It’s interesting that in HTx patients, it shows compensatory enhancement due to increased pulmonary vascular resistance.
