In normal circumstances left ventricular (LV) apex and base rotate different directions during cardiac cycle, while LV apex rotates counterclocwise, LV base has a clockwise movement at the same time. This sort of towel-wringing-like movement is called LV twist. Three-dimensional speckle-tracking echocardiography (3DSTE) is a new, promising, easy-to-perform and reproducible modality for the evaluation of LV apical and basal rotations. Although cardiac adaptation is a known feature seen in highly trained athletes, there are conflicting results according to sport activity-related changes in LV rotational mechanics. The present study was designed to test whether differences in LV rotational mechanics could be detected in elite athletes with high dynamic, but different grade of static components of their training by 3DSTE. Methods. The subjects group comprised 80 elite sportmen, which group of athletes was further divided according to the task force classification of the American College of Cardiology considering dynamic and static components of their training. The following groups were created regarding to their physical activity: Group C1 (high dynamic/low static)(n = 13, mean age: 24.0 ± 5.1 years, Group C2 (high dynamic/moderate static)(n = 23, mean age: 24.6 ± 7.7 years) and Group C3 (high dynamic/high static)(n = 34, mean age: 22.8 ± 6.0 years). Their results were compared to 67 age- and gender-matched non-athletic healthy controls (mean age: 24.0 ± 5.1 years, 33 men). 3DSTE was used for the evaluation of LV rotational abnormalities. Results. Increased LV end-diastolic and end-systolic volumes could be detected in Groups C2 and C3 subjects as compared to controls. No changes in LV volumes and rotational mechanics could be detected in Group C1 cases. Reduced LV basal rotation was seen in Group C2 and C3 subjects compared to that of controls (-3.17 ± 2.81 degree and -2.88 ± 1.88 degree vs. -4.31 ± 1.82 degree, p < 0.05 and p < 0.05, respectively). It was accompanied with LV twist reduction in Groups C2 and C3 subjects compared to that of controls (11.3 ± 4.3 degree and 11.5 ± 4.1 degree vs. 14.0 ± 3.4 degree, p < 0.05 and p < 0.05, respectively). None of elite athletes showed absence of LV twist called as LV ‘rigid body rotation’ (LV-RBR). Conclusions. Significant LV basal rotation and twist reduction could be detected in elite athletes with high dynamic and moderate/high static components of their training.

Abstract Introduction Tetralogy of Fallot (TOF) is the most common cyanotic congenital heart disease. Abnormal aortic dimensions and elasticity parameters have been long described for corrected TOF (cTOF) together with left ventricular (LV) rotational abnormalities. The present study focuses on investigating LV rotational mechanics in cTOF, and possible correlation of these parameters with aortic elastic properties. It was also aimed to be examined whether different surgical strategies has any effect on the results. Methods The study involved 26 adult cTOF patients, from which 14 had palliative surgery first [Blaloc-Taussig (n=10), Waterstone-Cooley (n=2) shunts, or Brock procedure (n=2)] (mean age at the repair: 7.3±10.2 years) and a late total correction (mean age at the repair: 10.0±13.3 years) (pcTOF), while the early total correction was the treatment of choice in 12 patients (mean age at the repair: 4.2±3.2 years) (etrTOF). Their results were compared to that of 37 age- and gender-matched healthy adults. Routine transthoracic two-dimensional Doppler echocardiography extended with assessment of aortic elastic properties and three-dimensional speckle-tracking echocardiography (3DSTE) was performed in all cTOF patients and controls. Results Sixteen out of 26 cTOF patients showed normally directed LV rotational mechanics, while apical and basal LV rotations were in the same clockwise and counterclockwise directions in 7 and 3 cTOF cases, respectively (38%). This sort of LV movement is called as LV rigid body rotation (RBR). The ratio of LV-RBR between etrTOF and pcTOF patients did not differ significantly (33% vs. 43%, p=0.70). Significantly reduced LV apical rotation (5.2±3.7 degree vs. 10.2±4.5 degree, p<0.05) and twist (9.0±3.3 degree vs. 14.6±4.9 degree, p<0.05) could be demonstrated in cTOF patients with normally directed LV rotational mechanics with preserved LV basal rotation regardless of previous procedure. pcTOF patients showed significantly reduced LV apical rotation as compared to that of etrTOF cases (3.2±3.7 degree vs. 7.1±2.5 degree, p<0.05). From the 7 cTOF patients with clockwise LV-RBR, apical and basal LV rotation proved to be −6.8±5.4 degree and −4.9±2.4 degree, respectively with LV apico-basal gradient of 4.3±3.6 degree. The mean LV apical and basal LV rotation of 3 cTOF patients with counterclockwise LV-RBR prove to be −2.1±3.4 degree and 0.2±0.9 degree, respectively with LV apico-basal gradient of 2.5±2.4 degree. Significant correlations could be demonstrated between LV apical rotation and aortic stiffness index (r=−0.55, p=0.03) and aortic distensibility (r=0.52, p=0.04). Conclusions Significant LV rotational abnormalities could be demonstrated in cTOF with the high prevalence of LV-RBR. cTOF patients with early total reconstruction proved to have beneficial results. Abnormal physiologic response of LV rotational mechanics to increased aortic stiffness can be detected in cTOF patients without LV-RBR. Funding Acknowledgement Type of funding source: None

AbstractIntroductionLeft ventricular (LV) twist is considered an essential part of LV function due to oppositely directed LV basal and apical rotations. Several factors could play a role in determining LV rotational mechanics in normal circumstances. This study aimed to investigate the relationship between LV rotational mechanics and mitral annular (MA) size and function in healthy subjects.MethodsThe study comprised 118 healthy adult volunteers (mean age: 31.5 ± 11.8 years, 50 males). All subjects had undergone complete two-dimensional (2D) Doppler echocardiography and three-dimensional speckle-tracking echocardiography (3DSTE) at the same time by the same echocardiography equipment.ResultsThe normal mean LV apical and basal rotations proved to be 9.57 ± 3.33 and −3.75 ± 1.98°, respectively. LV apical rotation correlated with end-systolic MA diameter, area, perimeter, fractional area change, and fractional shortening, but did not correlate with any end-diastolic mitral annular morphologic parameters. The logistic regression model identified MA fractional area change as an independent predictor of ≤6° left ventricular apical rotation (P < 0.003).ConclusionsCorrelations could be detected between apical LV rotation and end-systolic MA size and function, suggesting relationships between MA dimensions and function and LV rotational mechanics.

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.
