Aim of the study was to test the feasibility of transthoracic real-time 3D (Philips) echocardiography (RT3D) during parabolic flight, to allow direct measurement of heart chambers volumes modifications during the parabola. One RT3D dataset corresponding to one cardiac cycle was acquired at each gravity phase (1 Gz, 1.8 Gz, 0 Gz, 1.8 Gz) during breath-hold in 8 unmedicated normal subjects (41 +/- 8 years old) in standing upright position. Preliminary results, obtained by semi-automatically tracing left ventricular (LV) and left atrial (LA) endocardial contours in multiple views (Tomtec), showed a significant (p0.05) reduction, compared to 1 Gz, of LV and LA volumes with 1.8 Gz, and a significant increase with 0 Gz. Further analysis will focus on the right heart.

Background— Mitral and aortic valves are known to be coupled via fibrous tissue connecting the two annuli. Previous studies evaluating this coupling have been limited to experimental animals using invasive techniques. The new matrix array transesophageal transducer provides high-resolution real-time 3D images of both valves simultaneously. We sought to develop and test a technique for quantitative assessment of mitral and aortic valve dynamics and coupling. Methods and Results— Matrix array transesophageal (Philips iE33) imaging was performed in 24 patients with normal valves who underwent clinically indicated transesophageal echocardiography. Custom software was used to detect and track the mitral and aortic annuli in 3D space throughout the cardiac cycle, allowing automated measurement of changes in mitral and aortic valve morphology. Mitral annulus surface area and aortic annulus projected area changed reciprocally over time. Mitral annulus surface area was 8.0�2.1 cm 2 at end-diastole and decreased to 7.7�2.1 cm 2 in systole, reaching its maximum (10.0�2.2 cm 2 ) at mitral valve opening. Aortic annulus projected area was 4.1�1.2 cm 2 at end-diastole, then increased during isovolumic contraction reaching its maximum (4.8�1.3 cm 2 ) in the first third of systole and its minimum (3.6�1.0 cm 2 ) during isovolumic relaxation. The angle between the mitral and aortic annuli was maximum (136�13�) at end-diastole and decreased to its minimum value (129�11�) during systole. Conclusions— This is the first study to report quantitative 3D assessment of the mitral and aortic valve dynamics from matrix array transesophageal images and describe the mitral-aortic coupling in a beating human heart. This ability may have impact on patient evaluation for valvular surgical interventions and prosthesis design.

The recently developed echocardiographic matrix array transesophageal (mTEE) transducer provides real-time 3D images of high spatial and temporal resolution that may be suitable for detailed simultaneous study of functional anatomy of the mitral and aortic valves. We developed software that detects and tracks throughout the cardiac cycle mitral and aortic annuli (MA and AoA) and tested it in 15 patients with normal valves. Following manual initialization of each annulus in 15 planes rotated around the valvepsilas axis, the position of each annulus was tracked using a two-step 3D feature tracking algorithm based on maximum likelihood and Lucas-Kanade optical flow techniques and parameters of valve geometry were automatically measured throughout the cardiac cycle. Frame-by-frame detection and tracking of MA and AoA was possible in all patients. This approach allowed for the first time non-invasive quantitative measurements of the 3D dynamic geometry of normal MA and AoA and their coupling from mTEE data.

Quantitative information on regional left ventricular (LV) function from real-time 3D echocardiographic (RT3DE) images has significant clinical potential, but needs validation. Our goals were to validate these measurements against cardiac magnetic resonance (CMR) and test the feasibility of automated detection of regional wall motion (RWM) abnormalities from RT3DE data. RT3DE and CMR images were obtained in 31 pts and analyzed using prototype software to calculate regional volumes and ejection fractions. Indices were compared between RT3DE and CMR. Additionally, CMR images were reviewed by an expert, whose RWM grades were used as a reference for the automated detection of RWM abnormalities. RT3DE measurements resulted in good agreement with CMR. Automated detection showed high levels of agreement with expert reading, similar for CMR and RT3DE. Analysis of RT3DE data provides accurate quantification of regional function and allows automated detection of RWM abnormalities.

- Abstract
Aortic stenosis (AS) is the most common native valve disease. The assessment of its severity is routinely performed using transthoracic 2D echocardiography. In particular, aortic valve area (AVA) is usually assessed by continuity equation, although this measurement relies on geometrical assumptions, or by planimetry on transesophageal echocardiography. Accordingly, the aim of this study was to develop and test a new technique to assess the severity of AS using data acquired with realtime 3D matrix transesophageal echocardiographic (MTEE) probe. We studied 20 patients undergoing clinically indicated TEE. MTEE imaging was performed in 10 subjects with normal mitral and normal aortic valves and in 10 patients with moderate to severe AS (AVA < 1.4 cm²) and normal mitral valve. Our technique allowed quantitative volumetric measurements of dynamic AV parameters, and thus constitutes a new tool for objective assessment of the severity of AS.
