Transesophageal echocardiographically detected atherosclerotic aortic plaque is a marker for coronary artery disease.
The aim of this study was to test the hypothesis that atherosclerotic plaque in the thoracic aorta detected by transesophageal echocardiography is a marker for coronary artery disease. ⋯ The detection of atherosclerotic plaque in the thoracic aorta by transesophageal echocardiography appears to be a marker for the identification of obstructive coronary artery disease and deserves further investigation.

Syncope in advanced heart failure: high risk of sudden death regardless of origin of syncope.
The purpose of this study was to assess the importance of syncope as a warning sign for sudden death in advanced heart failure and to determine the relative importance of cardiac syncope and syncope from other causes. ⋯ Patients with advanced heart failure are at especially high risk for sudden death regardless of the etiology of syncope.

Intracardiac echocardiography in humans using a small-sized (6F), low frequency (12.5 MHz) ultrasound catheter. Methods, imaging planes and clinical experience.
This study was designed to determine the clinical utility and feasibility of using 12.5-MHz ultrasound catheters for intracardiac echocardiography. ⋯ Intracardiac echocardiography with 12.5-MHz ultrasound catheters is safe and feasible; it also provides anatomic and physiologic information. This feasibility study provides a foundation for wider clinical use of intracardic echocardiography.

Prognosis in cardiogenic shock after acute myocardial infarction in the interventional era.
The purpose of this study is to describe the outcome in cardiogenic shock treated with aggressive reperfusion therapy and to identify factors predictive of in-hospital and long-term mortality. ⋯ In a large consecutive series of patients with cardiogenic shock with complete follow-up, patency of the infarct-related artery was most strongly associated with in-hospital and long-term mortality. This finding supports an aggressive interventional strategy in patients with cardiogenic shock.

Comparative StudyComparison of transthoracic and transesophageal echocardiography in evaluation of 47 Starr-Edwards prosthetic valves.
Our objectives were to characterize by transesophageal echocardiography the normal appearance of the Starr-Edwards prosthetic heart valve and to compare the utility of transesophageal and transthoracic echocardiography in detection of valve abnormality. ⋯ These observations demonstrated the unique utility of transesophageal echocardiography in patients with Starr-Edwards prosthetic valve dysfunction, endocarditis or thrombus formation, and of the clear superiority of transesophageal echocardiography over transthoracic echocardiography in these situations.
