| Tartalmi kivonat: | Background/Objectives: The aortic valve has a prominent role in regulating blood flow and is of exceptional importance in clinical cardiological practice, as it can be affected by numerous abnormalities, so any clinical study that examines its physiological properties may be of significance. It is known that the dimensions of the aortic valve annulus (AVA) not only change during the cardiac cycle, but also undergo spatial displacement. Considering this, the question arises as to whether the AVA’s dimensions and their spatial displacement, represented by aortic annular plane systolic excursion (AAPSE), are related or not. Therefore, these parameters were simultaneously assessed using three-dimensional speckle-tracking echocardiography (3DSTE) in healthy adults. Methods: The present study’s cohort consisted of 148 healthy adults (mean age: 34.8 ± 12.4 years, 80 men). In all cases, two-dimensional Doppler echocardiography and 3DSTE were performed, the latter being used to assess the aortic valve. Results: In all subjects, end-diastolic and end-systolic AVA dimensions showed no association with an increase in AAPSE. In subjects with a greater end-diastolic AVA area (AVA-A), end-systolic AVA dimensions tended to decrease with increasing AAPSE; this trend reached statistical significance for end-systolic minimum AVA diameter, when comparing participants with AAPSE below versus above the mean. With increasing end-diastolic AVA-A, all other AVA parameters increased accordingly in all subjects and regardless of which AVA-A proved to be greater. In all subjects, and in those with a greater end-systolic AVA-A, the AAPSE proved to be similar regardless of the size of the end-diastolic AVA-A. In cases with a greater end-diastolic AVA-A, only one subject showed a very small end-diastolic AVA-A. With increasing end-systolic AVA-A, all other AVA dimensions were increased in all subjects and in cases with a greater end-diastolic or end-systolic AVA-A. AAPSE showed no significant differences between the subgroups examined, although it tended to be lower in cases with a greater end-diastolic AVA-A and the largest end-systolic AVA-A, and in subjects with a greater end-systolic AVA-A and the smallest end-systolic AVA-A. Moreover, individuals with a greater end-diastolic AVA-A and the smallest end-systolic AVA-A had a tendency for increased AAPSE. No correlations were present between AVA dimensions and AAPSE. Conclusions: 3DSTE-derived AVA dimensions showed no obvious associations with AAPSE in the same healthy adults. |
