Three-dimensional echocardiographic evaluation of right ventricular volume and function in pediatric patients: validation of the technique.
The right ventricle (RV) is the main ventricular chamber in many congenital heart diseases before and after surgical correction, and it is the most important determinant of outcome in postoperative tetralogy of Fallot and other complex malformations. Unfortunately its irregular crescentic shape does not allow the use of the geometric assumption used for the left ventricle. Many methods have been suggested in the literature to overcome this problem, none fully reliable. ⋯ The coefficient of repeatability was 4.79 mL with all the values within this range (2 SD of the mean). We conclude that 3DE provides an accurate measurement of RV volume in pediatric patients with RV volume overload. It is a reliable, noninvasive, and nongeometric method of evaluation of the volume of this chamber, and can be considered a precious tool in the armamentarium of the pediatric cardiologist.

Case ReportsLeft valsalva sinus aneurysm rupture into left atrium and aortic valve prolapse confirmed with transesophageal echocardiography.
We report a very rare case of left Valsalva sinus aneurysm rupture into left atrium in a 55-year-old man with severe aortic regurgitation caused by aortic valve prolapse. The Valsalva sinus aneurysm rupture was clearly visualized with transesophageal echocardiography performed to further delineate the aortic valve pathology. The 3-dimensional reconstruction of multislice computed tomography images nicely visualized the left Valsalva sinus aneurysm.
