Objective: To assess prospectively, in healthy subjects and in patients with dilated cardiomyopathy (DCM) and hypertrophic obstructive cardiomyopathy (HOCM), the 3-dimensional (3D) shape, size, and motion of the mitral annulus (MA) using computed tomography (CT).
Materials And Methods: Twenty patients with no cardiac abnormalities (referred to as normals), 15 with DCM, and 15 with HOCM as determined by echocardiography underwent contrast-enhanced, retrospectively electrocardiography (ECG)-gated 64-slice CT of the heart. The MA was manually segmented in 10% steps of the RR interval with dedicated 3D software employing the point-wrap algorithm.
Objectives: We sought to determine the agreement for the quantification of cardiac chamber dimensions, volumes, and myocardial mass between dual-source computed tomography (DSCT) and echocardiography.
Material And Methods: One-hundred patients underwent DSCT and transthoracal echocardiography within 1 week. Measurements of dimensions were obtained in standardized planes in end-systole and end-diastole and included the anterior-posterior diameter of the left atrium, septal and posterior wall thickness, and inner diameter of the left ventricle.
Objective: Tricuspid valve replacement in children is associated with a nonnegligible complication rate because of specific disadvantages of mechanical or biologic prostheses. The objective of this study was to examine the midterm clinical outcomes of tricuspid valve replacement with a mitral homograft in 8 children with unreparable rheumatic tricuspid valve involvement.
Methods: Between 1993 and 2003, tricuspid valve replacement with a mitral homograft was performed in 8 patients (2 male and 6 female patients; mean age, 14.
