Background and Purpose— Warfarin prevents stroke in atrial fibrillation (AF); however, concerns regarding international normalized ratio control and hemorrhage limit its use in the elderly. The oral direct thrombin inhibitors (DTIs) are potential alternatives to warfarin, offering fixed dosing without drug and dietary interactions and the need for international normalized ratio monitoring. Although ximelagatran, a DTI studied in the Stroke Prevention using an ORal Thrombin Inhibitor in atrial Fi...

Abstract The aim of this study was to evaluate the risk of performing cardiac catheterization or intraaortic balloon pump placement in patients with transesophageal echocardiographically detected atherosclerotic aortic debris. Cardiac catheterization was performed in 70 patients with atherosclerotic aortic debris (in 11 via the brachial approach and in 59 via the femoral approach) and in 71 control patients. An embolic event occurred in 10 (17%) of 59 patients with atherosclerotic aortic debris ...

Arterial embolization from thrombolytic therapy for acute myocardial infarction is rare. We report two cases of spontaneous arterial embolization following the use of tissue plasminogen activator for acute myocardial infarction. Transesophageal echocardiography was able to identify the source of embolism as mobile atherosclerotic debris within the thoracic aorta. This information was of value in the management of these patients, in that femoral catheterization which could have precipitated furth...

Previous studies assessing the value of transthoracic echocardiography (TTE) in blunt chest trauma are limited because patients with severe chest wall injury often have suboptimal echocardiographic findings. Transesophageal echocardiography (TEE) can provide high quality images when the transthoracic image quality is poor. To provide complete echocardiographic assessment of cardiac structure and function we prospectively performed TTE in 105 patients with severe blunt chest trauma and TEE in 20 ...

Abstract Transesophageal 2-dimensional echocardiography provides high-quality images of the thoracic aorta. 1,2 Although this display technique is generally quite adequate for diagnosis, it does not optimally communicate the 3-dimensional nature of the anatomy and the full extent of pathology. Therefore, the purpose of this study was (1) to evaluate the feasibility of generating 3-dimensional images of the descending thoracic aorta from sequential 2-dimensional transesophageal echocardiographic ...

Clinically, severe right ventricular contusion may mimic cardiac tamponade. We report two cases of suspected cardiac tamponade after blunt chest trauma in which the diagnosis of severe right ventricular contusion was made only by transesophageal echocardiography, avoiding unnecessary and hazardous pericardiocentesis. These cases illustrate the value of transesophageal echocardiography in diagnosing blunt chest trauma.

Acute paraplegia must be investigated promptly to exclude reversible causes. In this report we illustrate the usefulness of transesophageal echocardiography in identifying the vascular etiologies of acute paraplegia.Two patients presented with acute paraplegia, one spontaneously and the other after removal of an intra-aortic balloon pump catheter. Through the use of transesophageal echocardiography, we excluded aortic dissection and identified protruding atherosclerotic plaques in the descending...

Superior vena caval (SVC) syndrome may be caused by extravascular compression or intravascular obstruction. Knowing the mechanism of SVC syndrome enables the physician to choose appropriate treatment. Transesophageal echocardiography (TEE) is a safe bedside procedure that is excellent for evaluating the SVC and its surrounding structures. We report the valuable role of TEE in demonstrating the mechanism of SVC syndrome.
