The aims of this study were i) to evaluate mitral and aortic annuli excursion, and aortomitral angle (AMA) during the cardiac cycle in healthy adults using two-dimensional speckle tracking echocardiography, ii) to assess two annuli dynamics and coupling behaviors as an integral, and iii) to detect the relation between two annuli and left ventricular ejection fraction (LVEF). A total of 74 healthy adults underwent transthoracic echocardiography. In the parasternal long-axis view, a number of points were extracted, including right coronary aortic annular, aortomitral fibrous junction, and posterior mitral annular points. The annuli excursion and AMA were measured using a speckle tracking-derived software during the cardiac cycle. During the isovolumic contraction and the isovolumic relaxation phase, annuli excursion and AMA remain stable for a short time. During the systole, annuli excursion increased sharply to the maximum, while AMA narrowed quickly to the minimum value. During the diastole, there are three patterns of decrease in annuli excursion and AMA expansion in different phases. The annuli excursion of three points correlates well with the LVEF (right coronary aortic annulus excursion, r=0.71, P<0.05; non-coronary aortic annulus excursion, r=0.70, P<0.05; posterior mitral annulus excursion, r=0.82, P<0.05). Moreover, there are positive correlations between annuli excursion and the variation of AMA (r=0.60, P<0.05). The annuli excursion and AMA have various regular patterns in healthy adults. The interactions of mitral and aortic annuli correlate with the left ventricular function. Our findings may have relevance to the evaluation of left ventricular function and presurgical planning of patients with valvular diseases.

Active Acromegaly

Abstract Introduction Acromegaly is a relatively rare, chronic hormonal disease resulting in disfigurement. In 90% of the cases, acromegaly is caused by a benign pituitary monoclonal human growth hormone-secreting tumor. Hypertension and left ventricular (LV) hypertrophy are the most common cardiovascular comorbidites, but serious valvular regurgitation and heart failure could also develop at the end-stages. The aim of the present study was to determine the presence of LV deformational abnormalities using three-dimensional speckle-tracking echocardiography (3DSTE) in a group of acromegaly patients. Methods Thirty-eight acromegaly patients were involved in the present study. Thirteen patients were excluded due to inadequate image quality. The mean age of the remaining patients were 57.2 ± 13.6 years (7 males). The active acromegaly subgroup consisted of 14 patients (mean age: 58.6 ± 14.6 years, 5 males), while the inactive group contained 11 patients (mean age: 54.0 ± 12.9, 2 males). Their data was compared to an age- and gender matched control population, which comprised of 34 healthy volunteers (mean age: 52.7 ± 4.9 years, 15 males). All subjects have undergone complete two-dimensional Doppler echocardiography extended with 3DSTE. Results Significant differences in left atrial diameter and volume, LV end-diastolic diameter and volume, interventricular septum and LV posterior wall thickness could be demonstrated between the acromegaly group and healthy controls. Global and mean segmental 3DSTE-derived LV radial strain (RS)(33.2 ± 13.4% vs. 25.2 ± 10.8%, p =0.01 and 36.0 ± 12.1% vs. 28.2 ± 10.0%, p =0.009, respectively) proved to be significantly higher in acromegaly patients compared to controls. Active acromegaly patients had a significantly higher global and mean segmental RS (35.5 ± 14.4% vs. 25.2 ± 10.8%, p =0.03 and 37.9 ± 13.3% vs. 28.2 ± 10.0%, p =0.03, respectively) as compared to that of controls. Between active and inactive acromegaly groups only basal LV circumferential strain (-30.2 ± 4.8% vs. -26.7 ± 4.1%, p =0.02) was found to be significantly different. Conclusion With presented clinical, demographic, therapeutic and echocardiographic features, active acromegaly is associated with enhanced LV-RS as compared to the healthy population.
