Coexistence of bicuspid aortic and pulmonary valves in the same patient is a very rare entity identified mainly during surgery and postmortem. To the best of our knowledge, only one case has been diagnosed by two‐dimensional echocardiography in a newborn with malposition of the great arteries but no images were presented. Here, we are reporting the first case of bicuspid pulmonary and aortic valves diagnosed by live/real time three‐dimensional transesophageal echocardiography in an adult with normally related great arteries. 相似文献

Incremental benefit of three‐dimensional transthoracic echocardiography in the assessment of left atrial appendage aneurysm leading to severe extrinsic compression of a coronary artery 下载免费PDF全文
Rohit Tandon MD Mohammed J. Arisha MD Navin C. Nanda MD Sooraj Kumar MD Gurpreet S. Wander MD Swetha Srialluri MD Hassan Kamel MD Ahmed Y. Salama MBChB 《Echocardiography (Mount Kisco, N.Y.)》2018,35(5):685-691
Left atrial appendage aneurysm (LAA AN) is a rare disease entity, which can be congenital or acquired in nature. We report an adult patient with LAA AN presenting with anginal chest pain in whom live/real time three‐dimensional transthoracic echocardiography (3DTTE) provided incremental value over the two‐dimensional (2D) technique in providing a more comprehensive assessment of the lesion. A literature review of the salient features of LAA AN is also provided in a tabular form. 相似文献

We describe the incremental value of live/real time three‐dimensional (3D) echocardiography over the 2D technique in the assessment of ruptured right sinus of Valsalva into the right ventricle associated with an adjacent perimembranous ventricular septal defect in an elderly patient. 相似文献

Left atrial appendage (LAA) has unique anatomical and physiological properties, which make it a common site for thrombus formation in many cardiovascular and systemic diseases. Assessment of LAA for thrombus thus becomes important in many clinical situations and two-dimensional transesophageal echocardiography (2D TEE), which allows excellent quality images of LAA because of its close proximity to esophagus is routinely used for this purpose. However, it is a semiinvasive procedure, requires more time and involves some degree of patient discomfort. With some training and experience, two-dimensional transthoracic echocardiography (2D TTE) can visualize LAA in most patients with good acoustic windows. A disadvantage of both 2D TTE and 2D TEE is that they provide only a thin slice or section of cardiac structures at any given time limiting their utility in comprehensively assessing the LAA for thrombus. On the other hand, live/real time three-dimensional (3D) TTE overcomes this limitation of both 2D TTE and 2D TEE because of its ability to encompass whole of the LAA in three-dimensions in the acquired data set, which can then be cropped and sectioned systematically at any desired angulation to more definitively look for clot. 3D TTE is also useful in differentiating a clot from pectinate muscles in the LAA, which can mimic a thrombus resulting in patient mismanagement. In addition, 3D TTE is helpful in sectioning a clot for lysis, which has implications in clot resolution. We reviewed the existing literature comparing the relative advantages and disadvantages of 3D TTE versus 2D TEE and found that in patients with good acoustic windows 3D TTE had similar efficacy for detecting LAA thrombus.

Incremental value of live/real time three‐dimensional transesophageal echocardiography in the assessment of ventricular septal rupture following acute myocardial infarction 下载免费PDF全文
Mohammed J. Arisha MD Ming C. Hsiung MD Navin C. Nanda MD Bulur Serkan MD Amier Ahmad MD Ahmed Elkaryoni MD Mahmoud Elsayed MD Leilani Adana MD Shravan Turaga MD Emel Guler MD Nermina Alagic MD 《Echocardiography (Mount Kisco, N.Y.)》2017,34(11):1680-1686
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. 相似文献
