Review Case ReportsTransesophageal echocardiographic features and management of retained intracardiac air in two patients after surgery.
Intracardiac residual air after open-heart surgery may carry a significant risk of embolization with associated morbidity and death. We hereby report two cases of retained intracardiac air detected in an unusual location with transesophageal echocardiography in the superior aspect of the left atrium after completion of standard air-evacuation procedures. Characteristic echocardiographic features and the impact on immediate management are described along with a review of the literature.

Review Case ReportsEchocardiographic diagnosis of right and left sinus of Valsalva aneurysms dissecting into the ventricular septum.
We report a case of dissection of the ventricular septum by two aneurysms of the right and left coronary sinuses of Valsalva. Transthoracic and transesophageal echocardiography allowed accurate preoperative assessment and postoperative evaluation.

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.

ReviewDoppler flow velocity patterns of the superior vena cava, inferior vena cava, hepatic vein, coronary sinus, and atrial septal defect: a guide for the echocardiographer.
Pulsed-wave Doppler provides the echocardiographer the advantage of range resolution; confusion as to the source of Doppler shift information is unusual. One area of the heart that may lead to interpretive difficulties, however, is the right atrium because the right atrium receives blood flow from three venous sources and from the left atrium when an atrial septal defect is present. Our article presents information on the normal pulsed-wave Doppler spectral displays for the superior vena cava, inferior vena cava, hepatic vein, and coronary sinus. Because it is clinically pertinent, methods on how to differentiate these normal venous flow patterns from atrial septal defect flow will be emphasized.
