RESUMO
BACKGROUND: The ascending aorta (AA) has not been well studied using two-dimensional right parasternal transthoracic echocardiographic examination (2DRPE). AIM: The aim of the present study was to assess the incremental value of 2DRPE over two-dimensional left parasternal transthoracic echocardiographic examination (2DLPE) in evaluating the size of AA in adult patients (pts) and, secondly, to determine whether live/real time three-dimensional (3D) RPE provided any additional benefit over 2DRPE. MATERIALS AND METHODS: The AA was successfully imaged by 2DLPE, 2DRPE, and 3D RPE in 87 of 141 (61.7%) pts which comprised of two groups of consecutive pts separated by an interval of 2 weeks. RESULTS: The maximum length of AA visualized by 2DRPE (4.98 ± 0.89) was larger than 2DLPE in 76/87(87%) pts (P < 0.001). Both the maximum systolic AA inner luminal width and leading edge-to-leading edge width by 2DRPE were greater than 2DLPE (P < 0.001). Similar to other noninvasive imaging modalities where mid-AA width is taken at level of right pulmonary artery, mid-AA width could also be taken at this level by 2DRPE in 79/87(91%) pts since this landmark was visualized during 2DRPE. However, this vessel could be visualized in only 2/87 (2%) pts with 2DLPE. 3DRPE conferred additional benefit over 2DRPE. The maximal AA length by 3DRPE was larger than 2DRPE in 60/87(69%) pts, and the maximal inner lumen and leading edge to leading edge widths were larger in 54/87(62%) and 66/87(76%) pts, respectively. CONCLUSION: Our preliminary study demonstrates significant incremental value of 2DRPE over 2DLPE in the assessment of AA. 3DRPE confers an additional advantage over 2DRPE.

We demonstrate the incremental value of live/real time three-dimensional transthoracic echocardiography (3DTTE) over the two-dimensional modality in the identification of all three cusps of the pulmonary valve in patients in whom only two leaflets could be detected by the latter technique. This was because of the ability of 3DTTE to view the cusps enface permitting assessment of relationship to one another and the surrounding cardiac structures. In addition, 3DTTE showed not only the potential errors that can occur in pulmonary valve cusp identification when the two-dimensional modality is used alone but also how some of these errors can be avoided by paying attention to the surrounding structures.

Hemangiomas are rarely found in the heart and pericardial involvement is even more rare. We report a case of primary pericardial hemangioma, in which three-dimensional transesophageal echocardiography (3DTEE) provided incremental benefit over standard two-dimensional images. Our case also highlights the importance of systematic cropping of the 3D datasets in making a diagnosis of pericardial hemangioma with a greater degree of certainty. In addition, we also provide a literature review of the features of cardiac/pericardial hemangiomas in a tabular form.

Ostial lesions represent a challenging clinical scenario and percutaneous intervention (PCI) of left main coronary artery ostial lesions has been associated with postintervention complications, including protrusion of deployed stents into a sinus of Valsalva or aortic root. We report a case of stent protrusion into the aortic root following aorto-ostial left main coronary artery PCI, in which three-dimensional transesophageal echocardiography (3DTEE) provided incremental benefit over standard two-dimensional images. Specifically, 3DTEE confirmed the presence of stent protrusion by allowing clear visualization of the stent scaffold, in addition to characterizing the relationship between the stent and surrounding structures.

Ascending aortic pseudoaneurysms (AO PSAs), if left untreated, are complicated by a high rate of rupture resulting in significant morbidity and mortality. New transcatheter modalities have emerged as acceptable surgical alternatives for their management. We present a case of an ascending aortic PSA in which intraoperative two- and three-dimensional transesophageal echocardiography (2DTEE and 3DTEE) provided a comprehensive assessment of the PSA in pre- and postclosure settings.

Ventricular septal rupture is a serious complication following acute myocardial infarctions and is associated with a significant mortality rate. Classically, two-dimensional transthoracic echocardiography has been used to diagnose this complication and visualize its location. Two-dimensional transesophageal echocardiography has supplemented the transthoracic approach by providing more accurate assessment of the defect size and in guiding closure both percutaneously and intraoperatively. This modality, however, is limited to two-dimensional views only, and a greater breadth of information is instead available through the use of three-dimensional transesophageal echocardiography. We present a series of 11 patients in which live/real time three-dimensional transesophageal echocardiography offered incremental benefits over two-dimensional imaging alone.

BACKGROUND: The noninvasive assessment of superior vena cava (SVC), crista terminalis (CT), and the right atrial appendage (RAA) has clinical implications in determining the right atrium (RA) pressure in adult patients in whom the inferior vena cava cannot be imaged, in planning electrophysiological procedures and for evaluation of thrombi in RA/RAA. It is difficult to image these structures using standard two-dimensional transthoracic echocardiography (2DTTE), but the right parasternal approach has shown promise in the very few studies published so far. AIM: The aim of this study was to show the feasibility of this approach and its usefulness in qualitative and quantitative assessments of these structures by both 2D and three (3D) TTE in patients with and without known cardiac pathologies. MATERIAL AND METHODS: The study consisted of 38 adult patients, 17 of whom had cardiac pathologies (Group 1) while the remainder (Group 2) had no evidence of heart disease clinically or by echocardiography. RESULTS AND CONCLUSION: Both SVC and RAA could be imaged by 2DTTE and 3DTTE in 53% of 40 patients (two separate groups of 20 consecutive patients) studied demonstrating the technical feasibility of this approach. SVC size and collapsibility, CT and RAA size, and RAA fractional shortening were evaluated in both groups by both 2D and 3DTTE. 3DTTE provided incremental value over 2DTTE by its ability to view en face the SVC in short axis and the base of RAA and RAA volumes resulting in more comprehensive assessment of their size and function.

Transcatheter aortic valve replacement (TAVR) has emerged as a highly effective minimally invasive treatment for symptomatically critical aortic stenosis (AS) in patients at high or prohibitive surgical risk. We report a case of staged transcatheter management of critical AS combined with an atrial septal defect (ASD) with attenuated anterior superior rim. The clinical result of this case suggests that both procedures can be safely performed simultaneously. Therefore, combined transcatheter treatment may appear as a possible strategy in patients with concomitant cardiac conditions.

We present two cases in whom live/real time three-dimensional transesophageal echocardiography (3DTEE) provided incremental value in the assessment of atherosclerotic disease in the aorta. In one patient, it identified additional atherosclerotic ulcers as well as thrombi within them which were missed by two-dimensional (2D) TEE. In both cases, the size of the large mobile atherosclerotic plaque was underestimated by 2DTEE as compared with 3DTEE. Furthermore, 3DTEE provided volume quantification of the thrombi and ulcers which is not possible by 2DTEE. The echocardiographic findings of atherosclerotic plaques were confirmed by computed tomography in one patient and by surgery in the other.

An atrial septal pouch (ASP) results from partial fusion of the septum primum and the septum secundum, and depending on the site of fusion, the pouch can be left-sided (LASP) or right-sided (RASP). LASPs have been described in association with thrombi found in patients admitted with acute strokes, raising awareness of its potential cardioembolic role, especially in those with no other clearly identifiable embolic source. We retrospectively studied 39 patients in whom the presence of an ASP had been identified by three-dimensional transesophageal echocardiography (3DTEE) and who had a two-dimensional transesophageal echocardiogram (2DTEE) performed during the same clinical encounter. The incremental value provided by 3DTEE over 2DTEE included the detection of six ASPs not found by 2DTEE; the detection of two ASPs in the same subject (in four patients) not identified by 2DTEE; larger ASP measurements of length and height in over 80% of the cases; and measurement of the ASP width (elevational axis) for the calculation of the area of the ASP opening, because of its unique capability to view the pouch en face. In addition, the volume of ASP and of the echogenic masses contained in the ASP (four of 39 patients) could be calculated by 3DTEE, which is a superior parameter of size characterization when compared to individual dimensions. One of these patients who presented with ischemic stroke diagnosed by magnetic resonance imaging had a large (>2 cm) mass in a LASP, with echolucencies similar to those seen in thrombi and associated with clot lysis and resolution. This mass completely disappeared on anticoagulant therapy lending credence that it was most likely a thrombus. There was no history of stroke or any other type of embolic event in the other three patients with masses in ASP. In conclusion, this retrospective study highlights the incremental value of 3DTEE over 2DTEE in the comprehensive assessment and characterization of ASPs, which can aid in the clarification of their role in cryptogenic stroke patients.

BACKGROUND: Few data exist on the relation of the 3-dimensional morphology of mitral valve and degree of mitral regurgitation (MR) in mitral valve prolapse. METHODS AND RESULTS: Real-time 3-dimensional transesophageal echocardiography of the mitral valve was acquired in 112 subjects, including 36 patients with mitral valve prolapse and significant MR (≥3+; MR+ group), 32 patients with mitral valve prolapse but no or mild MR (≤2+; MR- group), 12 patients with significant MR resulting from nonprolapse pathologies (nonprolapse group), and 32 control subjects. The 3-dimensional geometry of mitral valve apparatus was measured with dedicated quantification software. Compared with the normal and MR- groups, the MR+ group had more dilated mitral annulus (P<0.0001), a reduced annular height to commissural width ratio (AHCWR) (P<0.0001) indicating flattening of annular saddle shape, redundant leaflet surfaces (P<0.0001), greater leaflet billow volume (P<0.0001) and billow height (P<0.0001), longer lengths from papillary muscles to coaptation (P<0.0001), and more frequent chordal rupture (P<0.0001). Prevalence of chordal rupture increased progressively with annulus flattening (7% versus 24% versus 42% for AHCWR >20%, 15%-20%, and <15%, respectively; P=0.004). Leaflet billow volume increased exponentially with decreasing AHCWR in patients without chordal rupture (r(2)=0.66, P<0.0001). MR severity correlated strongly with leaflet billow volume (r(2)=0.74, P<0.0001) and inversely with AHCWR (r(2)=0.44, P<0.0001). In contrast, annulus dilatation but not flattening occurred in nonprolapse MR patients. An AHCWR <15% (odds ratio=7.1; P=0.0004) was strongly associated with significant MR in mitral valve prolapse. CONCLUSION: Flattening of the annular saddle shape is associated with progressive leaflet billowing and increased frequencies of chordal rupture and may be important in the pathogenesis of MR in mitral valve prolapse.

BACKGROUND: Ascending aortic pseudoaneurysm (PsA) is an uncommon but surgically challenging problem with high morbidity and mortality. Herein we describe the efficacy and safety of the different approaches to transcatheter intervention for repair of ascending PsA and assess the selection of occluder devices using real-time 3-dimensional (RT 3D) color Doppler transesophageal echocardiography (TEE).METHODSâANDâRESULTS: Three patients with complex ascending PsA after cardiac or aortic root surgery were treated with transcatheter intervention due to high risk for redo surgery. Perioperative RT 3D-TEE combined with fluoroscopy was used for monitoring. All ascending PsA were successfully occluded with different devices using the transcatheter technique either with the transapical, transarterial approach, or transvenous combined with hybrid process depending on lesion anatomy. CONCLUSIONS: Treatment of complex ascending PsA with transcatheter or combined hybrid intervention with cautious planning based on patient presentation and well-coordinated teamwork was successful. RT 3D color Doppler TEE provided precise information for the selection of appropriate occluder device, and also facilitated the procedure by guiding the catheter through difficult anatomy.

Currently, tricuspid valve infective endocarditis (TVIE) is encountered in daily clinical practice more frequently due to the increasing prevalence of illicit intravenous drug use and the implantation of intracardiac devices. In this study, we compared findings from intra-operative live/real time three-dimensional transesophageal echocardiograms (3DTEE) and two-dimensional transesophageal echocardiograms (2DTEE) of 10 patients who underwent surgery for native tricuspid valve (TV) endocarditis. Unlike 2DTEE, 3DTEE allowed en face visualization of the 3 TV leaflets from both, atrial and ventricular aspects, in 9 of the 10 cases. In the remaining patient, in whom 3DTEE could not identify all 3 leaflets en face, the TV was found essentially destroyed at surgery. Using 3DTEE, the number of vegetations was accurately reported when compared with the surgical record. Furthermore, the orientation of each vegetation was the same as noted in the surgical findings. 2DTEE missed the identification of vegetations in 5 patients. The attachment site of vegetations to the TV were also not characterized by 2DTEE in 5 patients. In all 10 cases, 3DTEE characterized the vegetations more accurately with larger dimensions, including those in the azimuthal axis, and volumes. In addition, a perivalvular abscess that lead to surgical intervention was identified by 3DTEE, however, missed by 2DTEE. In conclusion, 3DTEE allows en face visualization of the TV apparatus permitting accurate description of the number and dimensions of vegetations identified by our surgical standard, which ultimately informs patients' prognosis and dictates the timing and planning for surgical intervention. Its use should be in conjunction with 2DTEE when evaluating TVIE.

A 2.5-year-old boy presented with frequent hospitalizations due to recurrent respiratory tract infections with dyspnea. A fibromuscular membrane dividing the left atrium with obstruction of left atrial inflow to the left ventricle was documented by two-dimensional transthoracic echocardiography (2DTTE). Live/real time three-dimensional transthoracic echocardiography (3DTTE) provided incremental value over 2DTTE by providing en face views of the 2 obstructing orifices in the membrane enabling accurate assessment of their position, shape and size. 3DTTE also showed clearly the location of the membrane superior and proximal to the left atrial appendage which was not well delineated by 2DTTE. In addition, 3DTTE demonstrated the full extent of the left atrial appendage and careful sequential cropping of the 3D dataset showed it to have 2 distinct lobes and no thrombus. These findings provided comprehensive assessment of the lesion and were helpful in surgical decision making and planning.

OBJECTIVES: This study assessed the ability of live/real time three-dimensional transesophageal echocardiography (3DTEE) in measuring (1) atrial septal defect (ASD) maximum dimension, area, and adjacent rim size, (2) ASD occluder left and right atrial disk size, (3) length of contact between the left atrial (LA) disk and the aorta, and in (4) assessing device related complications such as residual shunt, device embolization, and device encroachment upon adjacent cardiac structures. MATERIALS AND METHODS: 3DTEE images acquired during percutaneous ASD closure by the Amplatzer Septal Occluder in 15 adult patients were retrospectively analyzed. Offline analysis was done using both the Philips 5500 ultrasound system and Philips QLAB software. 3D color flow Doppler images were used to assess residual ASD shunting. RESULTS: The Philips 5500 and Philips QLAB measurements correlated well for ASD maximum dimension and area measurements. The Philips QLAB 3DTEE disk size measurements also correlated well with the manufacturer obtained sizes. The aortic rim was deficient in 7 of the 15 patients, and the mean ASD occluder device size was 4 mm greater than the mean ASD maximum dimension. The LA occluder disk was in contact with the aorta throughout the cardiac cycle in 12 of the 15 patients, and the LA occluder disk size correlated significantly with the contact length with the aorta. CONCLUSION: Most of the patients demonstrated contact between the LA occluder disk and the aorta throughout the cardiac cycle. 3DTEE may be useful in identifying patients at greater risk for aortic erosion.

Percutaneous closure of secundum atrial defects has become an accepted treatment in part because it is minimally invasive and relatively low risk. Despite recent advances in implantation technique and device improvements, complications occur. Here, we report a case of device embolization during percutaneous repair of an atrial septal defect (ASD) with multiple fenestrations. We highlight the value of using live/real time three-dimensional transesophageal echocardiography to help plan the percutaneous procedure and detect complications.

We compared findings from intraoperative live/real time three-dimensional transesophageal echocardiography (3DTEE) and two-dimensional transesophageal echocardiography (2DTEE) with surgery in 67 patients having aortic aneurysm and/or aortic dissection. Of these, 20 patients had aortic aneurysm without dissection, 21 aortic aneurysm and dissection, and 26 aortic dissection without aneurysm. 3DTEE diagnosed the type and location of aneurysm correctly in all patients unlike 2DTEE, which missed an aneurysm in one case. There were four cases of aortic aneurysm rupture. Three of them were diagnosed by 3DTEE but only one by 2DTEE, and one missed by both techniques. The mouth of saccular aneurysm, site of aortic aneurysm rupture, and communication sites between perfusing and nonperfusing lumens of aortic dissection could be viewed en face only with 3DTEE, enabling comprehensive measurements of their area and dimensions as well as increasing the confidence level of their diagnosis. In all patients with aortic dissection, 3DTEE enabled a more confident diagnosis of dissection because the dissection flap when viewed en face presented as a sheet of tissue rather than a linear echo seen on 2DTEE which can be confused with an artifact. 2DTEE missed dissection in one patient. In six cases the dissection flap involved the right coronary artery orifice by 3DTEE and surgery. These were missed by 2DTEE. Aortic regurgitation severity was more comprehensively assessed by 3DTEE than 2DTEE. Aneurysm size by 3DTEE correlated well with 2DTEE and surgery/computed tomography scan. In conclusion, 3DTEE provides incremental information over 2DTEE in patients with aortic aneurysm and dissection.
