Abstract The majority of cardiac myxomas (75–80%) are located within the left atrium, characteristically originating from the mid-portion of the atrial septum by a narrow stalk; The detection of such a feature has paramount importance for the diagnosis of myxoma ; in fact other anatomical findings as sessile implantation or other locations may be common to other cadiac tumors. Two dimensional (2D) transthoracic (TT) and transesophageal(TE) echocardiography E and cardiac magnetic resonance imaging (MRI) are mainstay in the diagnosis; It has been reported that Three dimensional(3D) E and in particular the 2D orthogonal cross sectional planes generated by electronically sectioning the 3D volume, could correctly identify the attachment and the peduncle sometimes missed by other imaging modality and therefore lead to a correct diagnosis. Purpose of our study was to assess the usefulness of 3DE in the detection of the mainstay anatomical features of the cardiac myxomas; We retrospectively reviewed all the case of the myxomas with pathology confirmation that underwent 2D TEE, 3D TEE and MRI in the past 5 years in order to assess the ability of the techniques in identifying the following anatomical features: site of attachment (mid atrial septum, other locations ) , modality of attachment (pedunculated or sessile); Every study was reviewed by an expert reader. Our study group is comprised by 7 patients, 6 female, mean age 48.8 ±9.7 with 12 myxomas ; 8 located in the left atrium 3 in the right atrium ; In 6 case was the first diagnosis , in one patient was a recurrence. 9 mixomas were in the left atrium , 3 in the right atrium. & were pedunculated, 5 sessile. There was an agreement in detecting the anatomical features except in two patients in a one patients the attachment by a peduncle in the atrial septum close to the opening of the left upper pulmonary vein was seen only by 3DE ; in a second patient a small myxoma close to the left atrial appendage was detected only by TEE ; Until now few reports have described the uselfuness of three dimensional echocardiography in detecting the anatomical features of cardiac myxomas. Even though MRI is the only technique able to detect perfusion of a mass otherwise it is not able to distinguish among different tumors; therefore the visualization of the anatomical features may lead a more correct diagnosis that can help in a better therapeutical and surgical plan. In our study 3DE was the only technique able to correctly depict the mainstay anatomical features of cardiac myxomas. It was possible in particular by using the 2D cross sectional planes generated by electronically sectioning the 3D volume in a case of a small peduncle attached in an uncommon location of the interatrial septum. All the techniques are reliable in assessing the anatomical features of myxomas however 3DE could have an additional value in particular in not common location and will compliment 2D imaging in cardiac myxoma diagnosis

AbstractIntroductionWe aimed to assess the ability of the multiplanar review modality of three-dimensional echocardiography to examine the dynamic morphology and the functional characteristics of malformed tricuspid valves in patients previously identified as having Ebstein’s malformation. Based on these characteristics, we attempted to differentiate Ebstein’s malformation from tricuspid valvar dysplasia.MethodsUsing three-dimensional multiplanar review, analysed with either Qlab 6.0 or Tomtech Image Arena 3.0, we studied 23 patients, aged from 1 day to 70 years, previously diagnosed using cross-sectional echocardiography as having Ebstein’s malformation.ResultsUsing the features of rotational abnormality, and the orientation, of the effective tricuspid valvar orifice as diagnostic features of Ebstein’s malformation, we reclassified 11 patients (48 per cent) as exhibiting tricuspid valvar dysplasia. In addition, we studied the dynamic morphology as well as the function of the tricuspid valve. Surgical treatment was undertaken on 10 patients, revealing good correlation with the findings obtained using three-dimensional multiplanar review. In those with Ebstein’s malformation, we found varying degrees of rotation, with the effective valvar orifice always directed towards the right ventricular outflow tract. The opening of the orifice of dysplastic tricuspid valves, in contrast, was towards the apex of the right ventricle. The degree of delamination, and abnormalities of subcordal apparatus, were similar in the two groups.DiscussionThree-dimensional multiplanar review permits accurate definition of the dynamic morphology of Ebstein’s malformation, permitting clear differentiation from tricuspid valvar dysplasia.

We report a case of a recurrence of 5 cardiac myxomas in both atria with atypical anatomical features difficult to image. Although a multimodality imaging was performed, three-dimensional echocardiography (3DE) was the only technique able to correctly identify all the recurrences and the anatomical characteristics of the myxomas. MRI detected the blood supply of the mass but even after careful review was able to identify only 4 of the 5 lesions. Even though it was already reported the usefulness of 3DE to better delineate the site of attachment of cardiac tumors, it was never reported its sensibility in the setting of multiple myxomas; this case highlights the ability of the 3DE in this challenging scenario and its potential for being considered the key adjunctive modality for the anatomy when advanced surgical plan is required.

Objective: To define the anatomic characteristics of the congenitally malformed and severely stenotic aortic valve using trans-thoracic real time three-dimensional echocardiography, and to compare and contrast this with the valvar morphology as seen at surgery. Design: Prospective cross-sectional observational study Setting: Tertiary centre for paediatric cardiology Methods: All patients requiring aortic valvotomy between December 2003 and July 2004 were evaluated prior to surgery with three-dimensional echocardiography. Full volume loop images were acquired using the Phillips Sonos 7500 system. A single observer analysed the images using “Q lab 4.1” software. The details were then compared with operative findings. Results: We identified 8 consecutive patients, with a median age of 16 weeks, ranging from 1 day to 11 years, with median weight of 7.22 kilograms, ranging from 2.78 to 22 kilograms. The measured diameter of the valvar orifice, and the number of leaflets identified, corresponded closely with surgical assessment. The sites of fusion of the leaflets were correctly identified by the echocardiographic imaging in all cases. Fusion between the right and non-coronary leaflets was identified in half the patients. Dysplasia was observed in 3 patients, with 1 patient having nodules and 2 shown to have excrescences. At surgery, nodules were excised, and excrescences were trimmed. The dysplastic changes correlated well with operative findings, though statistically not significant. Conclusion: We recommend trans-thoracic real time three-dimensional echocardiography for the assessment of the congenitally malformed aortic valve, particularly to identify sites of fusion between leaflets and to measure the orificial diameter. The definition of nodularity, and the prognosis of nodules based on the mode of intervention, will need a comparative study of patients submitted to balloon dilation as well as those undergoing surgical valvotomy

AbstractThe feasibility of rendering three dimensional (3D) pelvic models of vaginal, urethral and paraurethral lesions from 2D MRI has been demonstrated previously. To quantitatively compare 3D models using two different image processing applications: 3D Slicer and OsiriX. Secondary analysis and processing of five MRI scan based image sets from female patients aged 29–43 years old with vaginal or paraurethral lesions. Cross sectional image sets were used to create 3D models of the pelvic structures with 3D Slicer and OsiriX image processing applications. The linear dimensions of the models created using the two different methods were compared using Bland-Altman plots. The comparisons demonstrated good agreement between measurements from the two applications. The two data sets obtained from different image processing methods demonstrated good agreement. Both 3D Slicer and OsiriX can be used interchangeably and produce almost similar results. The clinical role of this investigation modality remains to be further evaluated.

Aortico-left ventricular tunnel is a rare congenital cardiac defect, which bypasses the aortic valve via the paravalvar connection from the aorta to the left ventricle. The authors report the history of a 14-year-old boy with aortico-left ventricular tunnel in whom the aortic orifice arose from the right aortic sinus and was closed by a pericardial patch. The diagnosis was confirmed by combined two-dimensional and real time three-dimensional echocardiogram and magnetic resonance imaging. This is the first case, in which these complex diagnostic imaging methods have been used in the pre- and postoperative management of this defect. Optimally the new transthoratic three-dimensional echocardiography would be needed to define the anatomy and functional consequences of the aortico-left ventricular tunnel and in the postoperative follow-up.

The tricuspid valve is currently the subject of much interest from echocardiographers and surgeons. Functional tricuspid regurgitation is the most frequent aetiology of tricuspid valve pathology, is characterized by structurally normal leaflets, and is due to annular dilation and/or leaflet tethering. A primary cause of tricuspid regurgitation with/without stenosis can be identified only in a minority of cases. Echocardiography is the imaging modality of choice for assessing tricuspid valve diseases. It enables the cause to be identified, assesses the severity of valve dysfunction, monitors the right heart remodelling and haemodynamics, and helps decide the timing for surgery. The severity assessment requires the integration of multiple qualitative and quantitative parameters. The recent insights from three-dimensional echocardiography have greatly increased our understanding about the tricuspid valve and its peculiarities with respect to the mitral valve, showing promise to solve many of the current problems of conventional two-dimensional imaging. This chapter provides an overview of the current state-of-the-art assessment of tricuspid valve pathology by echocardiography, including the specific indications, strengths, and limitations of each method for diagnosis and therapeutic planning.
