Case ReportsThe role of color flow Doppler in the echocardiographic diagnosis of mitral valve aneurysm.
A case of mitral valve aneurysm is presented in which infective endocarditis of the mitral valve was complicated by aneurysm formation 6 weeks later. The presence of mitral valve aneurysm was suspected on transthoracic echocardiography and confirmed by transesophageal echocardiography.

A 35-year-old woman had infective endocarditis and an aneurysm of the anterior mitral leaflet. The patient was managed conservatively and the mitral valve aneurysm remained stable over 3 years. Two-dimensional, color flow Doppler, and magnetic resonance images of the aneurysm are presented and features of mitral valve aneurysms are discussed. Conservative management of mitral valve aneurysms with careful follow-up is an acceptable approach.

Case ReportsHiatal hernia: the "X" factor in transesophageal echocardiography.
Two patients with large hiatal hernias underwent transesophageal echocardiographic examinations. In one case adequate images could not be obtained. In the other, skewed images and misleading information required other modes of investigation. We propose that the presence of a large hiatal hernia may lead to poor images or total inability to collect sonographic data.

ReviewAorta: comprehensive evaluation by echocardiography and transesophageal echocardiography.
The emergence of transesophageal echocardiography has made echocardiography a nearly ideal technique for evaluating the thoracic aorta. The echocardiographic anatomy of the aorta is reviewed. The role of echocardiography for evaluating aortic dissection, thoracic aortic aneurysm, aortic atherosclerosis, and thoracic aortic trauma is discussed. Comparison of echocardiography with other techniques for imaging the aorta (computed tomographic scan, nuclear magnetic resonance, and aortography) is presented.

Improved echocardiographic detection and characterization of left ventricular apical thrombi with a 5.0 MHz short-focus transducer.
Transthoracic echocardiography is a frequently used technique for detecting ventricular thrombi. This study compares the usefulness of a 5.0 MHz short focal length transducer (5-short) with standard frequency (2.5 or 3.5 MHz) transducers for the detection of left ventricular thrombi. In addition, the effect of body habitus on study quality was evaluated. ⋯ The studies positive only with the 5-short had significantly smaller calculated thrombi areas than those visualized by the standard transducers (1.6 +/- 1.2 vs 4.2 +/- 2.1 cm2, p = 0.02). No thrombus was detected by either technique in a normally contracting left ventricular apex. There were significantly fewer studies having near-field artifact when performed by the 5-short compared with those performed with standard transducers (14/101 vs 40/101, p = 0.00004).(ABSTRACT TRUNCATED AT 250 WORDS)
