“…However, this has not been widely adopted, partly because of the time-consuming off-line analysis. 17 Other nonechocardiographic methods such as multislice CT and MRI have also been successfully used for evaluation of the severity of AS [18][19][20][21][22] ; however, they are time consuming and have other known limitations compared with a simple bedside echo study. Recently, transthoracic real-time three-dimensional echocardiography (RT3D) has been introduced as a novel technique, which allows the spatial recognition of the anatomy and function of cardiac structures.…”

Background: Accurate assessment of aortic valve area (AVA) is important for clinical decision-making in patients with aortic valve stenosis (AS). The role of three-dimensional echocardiography (3D) in the quantitative assessment of AS has not been evaluated so far. Objectives: To evaluate the reproducibility and accuracy of real-time three-dimensional echocardiography (RT3D) and 3D-guided two-dimensional planimetry (3D/2D) for assessment of AS, and compare these results with those of standard echocardiography and cardiac catheterisation (Cath). Methods: AVA was estimated by transthoracic echo-Doppler (TTE) and by direct planimetry using transoesophageal echocardiography (TEE) as well as RT3D and 3D/2D. 15 patients underwent assessment of AS by Cath. Results: 33 patients with AS were studied (20 men, mean (SD) age 70 (14) 2 for TEE. Correlation coefficient r for AVA assessment between each of 3D/2D, RT3D, TEE planimetry and Cath was 0.81, 0.86 and 0.71, respectively. The intraobserver variability was similar for all methods, but interobserver variability was better for 3D techniques than for TEE (p,0.05). Conclusions: The 3D echo methods for planimetry of the AVA showed good agreement with the standard TEE technique and flow-derived methods. Compared with AV planimetry by TEE, both 3D methods were at least as good as TEE and had better reproducibility. 3D aortic valve planimetry is a novel non-invasive technique, which provides an accurate and reliable quantitative assessment of AS.

“…RT 3-D TEE is emerging as the preferred echocardiographic tool for the morphologic and functional characterization of the stenotic aortic valve [20][21][22][23][24][25] ( Figure 4). RT 3-D TEE facilitates the obtaining of the cross-sectional plane where the aortic valve area is smallest, usually at the tips of the leaflets.…”

Calcific aortic stenosis is now understood as a complex valvular degenerative process sharing many risk factors with atherosclerosis. Once patients develop symptomatic calcific aortic stenosis, the only effective treatment is aortic valve replacement. In the past decade, transcatheter aortic valve replacement (TAVR) has been developed as an alternative to surgery to treat severe calcific aortic stenosis. Cardiac imaging plays a pivotal role in the contemporary management of patients with calcific aortic stenosis, and particularly in patients being considered for TAVR, who demand detailed imaging of the aortic valve apparatus. In this review, we highlight the role of cardiac imaging for patient selection, procedural guidance, and evaluation of results of TAVR.

“…Nevertheless, it was found that adequate to excellent reconstruction of the aortic valve is feasible in more than 80% of patients, more commonly in native than in prosthetic valves [54]. Similar to mitral stenosis, in patients with aortic stenosis, TEE-based planimetry of the aortic valve is more accurate with 3D than with 2D imaging [55]. The use of 3D echocardiography in evaluating tricuspid valve disease has not been explored in-depth.…”

The introduction of three-dimensional (3D) imaging and its evolution from slow and labor-intense off-line reconstruction to real-time volumetric imaging is one of the most significant developments in ultrasound imaging of the heart of the past decade. This imaging modality currently provides valuable clinical information that empowers echocardiography with new levels of confidence in diagnosing heart disease. One major advantage of seeing the additional dimension is the improvement in the accuracy of the evaluation of cardiac chamber volumes by eliminating geometric modeling and the errors caused by foreshortened views. Another benefit of 3D imaging is the realistic views of cardiac valves capable of demonstrating numerous pathologies in a unique, noninvasive manner. This article reviews the major technological developments in 3D echocardiography and some of the recent literature that has provided the scientific basis for its clinical use.
