Case ReportsReal-time three-dimensional transesophageal echocardiographic imaging of cor triatriatum and persistent left superior vena cava.
The authors describe the case of a 54-year-old woman with the association of two rare congenital cardiac anomalies: cor triatriatum and persistent left superior vena cava with the special characteristic of direct drainage to the right atrium. Real-time three-dimensional transesophageal echocardiography offered a comprehensive anatomic and functional evaluation of these infrequent entities.

Real-time three-dimensional transesophageal echocardiography in patients with secundum atrial septal defects: outcomes following transcatheter closure.
Successful transcatheter closure of atrial septal defects (ASDs) requires the accurate assessment of defect size and morphology. Assessment of ASD anatomy may be difficult by two-dimensional (2D) echocardiography. The aim of this study was to test the hypothesis that real-time three-dimensional (3D) transesophageal echocardiography (TEE) may provide more accurate morphologic assessment of ASDs than multiplane 2D TEE. ⋯ Three-dimensional TEE can identify ASD shape. Maximal dimensions on 3D TEE were well correlated with balloon-stretched 2D dimensions. Two-dimensional TEE can underestimate the area of complex-shaped ASDs, which may result in residual right-to-left shunting.

Quantitative analysis of mitral valve apparatus in mitral valve prolapse before and after annuloplasty: a three-dimensional intraoperative transesophageal study.
Intraoperative real-time three-dimensional transesophageal echocardiography has been shown useful in the evaluation of the mitral valve (MV) apparatus, and dedicated commercial software allows its quantitative assessment. The aims of this study were to (1) quantify the effects induced by prolapse on MV anatomy in the presence of fibroelastic deficiency (FED) or Barlow's disease (BD), (2) assess the effect of surgery on the MV apparatus, and (3) investigate the potential role of three-dimensional transesophageal echocardiography in surgical planning. ⋯ Intraoperative three-dimensional transesophageal echocardiography allows quantitative evaluation of the MV apparatus in the presence of FED or BD and could be useful for immediate assessment of the surgical procedure.

Validation of noninvasive measurements of cardiac output in mice using echocardiography.
Although multiple echocardiographic methods exist to calculate cardiac output (CO), they have not been validated in mice using a reference method. ⋯ In mice, CO calculated from two-dimensional parasternal long-axis images is most accurate when compared with flow probe measurements; however, pulmonary VTI-derived CO is subject to less variability.

Practice GuidelineACCF/ASE/AHA/ASNC/HFSA/HRS/SCAI/SCCM/SCCT/SCMR 2011 Appropriate Use Criteria for Echocardiography. A Report of the American College of Cardiology Foundation Appropriate Use Criteria Task Force, American Society of Echocardiography, American Heart Association, American Society of Nuclear Cardiology, Heart Failure Society of America, Heart Rhythm Society, Society for Cardiovascular Angiography and Interventions, Society of Critical Care Medicine, Society of Cardiovascular Computed Tomography, Society for Cardiovascular Magnetic Resonance American College of Chest Physicians.
The American College of Cardiology Foundation (ACCF), in partnership with the American Society of Echocardiography (ASE) and along with key specialty and subspecialty societies, conducted a review of common clinical scenarios where echocardiography is frequently considered. This document combines and updates the original transthoracic and transesophageal echocardiography appropriateness criteria published in 2007 (1) and the original stress echocardiography appropriateness criteria published in 2008 (2). This revision reflects new clinical data, reflects changes in test utilization patterns,and clarifies echocardiography use where omissions or lack of clarity existed in the original criteria. ⋯ Routine testing when there was no change in clinical status or when results of testing were unlikely to modify management were more likely to be inappropriate than appropriate/uncertain. The AUC for echocardiography have the potential to impact physician decision making,healthcare delivery, and reimbursement policy. Furthermore,recognition of uncertain clinical scenarios facilitates identification of areas that would benefit from future research.
