Abstract

Integration of volumetric heart chamber quantification by 3D echocardiography into clinical practice has been hampered by several factors which a new fully automated algorithm (Left Heart Model, (LHM)) may help overcome. This study therefore aims to evaluate the feasibility and accuracy of the LHM software in quantifying left atrial and left ventricular volumes and left ventricular ejection fraction in a cohort of patients with a bicuspid aortic valve. Patients with a bicuspid aortic valve were prospectively included. All patients underwent 2D and 3D transthoracic echocardiography and computed tomography. Left atrial and ventricular volumes were obtained using the automated program, which did not require manual contour detection. For comparison manual and semi-automated measurements were performed using conventional 2D and 3D datasets. 53 patients were included, in four of those patients no 3D dataset could be acquired. Additionally, 12 patients were excluded based on poor imaging quality. Left ventricular end-diastolic and end-systolic volumes and ejection fraction calculated by the LHM correlated well with manual 2D and 3D measurements (Pearson’s r between 0.43 and 0.97, p

Abstract

Mitral annulus assessment is of great importance for the diagnosis and treatment of mitral valve disease. The present study sought to assess the value of real-time three-dimensional echocardiography for the assessment of true mitral annulus diameter (MAD).One hundred and fifty patients (mean age 38 +/- 18 years) with adequate two-dimensional (2D) echocardiographic image quality underwent assessment of MAD(2D) and MAD(3D) (with real-time three-dimensional echocardiography). In a subgroup of 30 patients true MAD was validated with magnetic resonance imaging (MRI).There was a good interobserver agreement for MAD(2D) (mean difference = -0.25 +/- 2.90 mm, agreement: -3.16, 2.66) and MAD(3D) (mean difference = 0.29 +/- 2.03, agreement = -1.74, 2.32). Measurements of MAD(2D) and MAD(3D) were well correlated (R = 0.81, P0.0001). However, MAD(3D) was significantly larger than MAD(2D) (3.7 +/- 0.9 vs. 3.3 +/- 0.8 cm, P0.0001). In the subgroup of 30 patients with MRI validation, MAD(3D) and MAD(MRI) were significantly larger than MAD(2D) (3.3 +/- 0.5 and 3.4 +/- 0.5 cm vs. 2.9 +/- 0.4 cm, both P0.001). There was no significant difference between MAD(MRI) and MAD(3D).MAD(3D) can be reliably measured and is superior to MAD(2D) in the assessment of true mitral annular size.
