Local thrombus as an isolated sign of traumatic aortic injury.

We report an unusual case of blunt traumatic aortic injury in which a mobile thrombus located at the isthmus was the only abnormality detected by transesophageal echocardiography. The case illustrates the high sensitivity of this diagnostic tool in aortic trauma and underscores the possibility of finding infrequent evidence of injury in subtle aortic lesions.

Left ventricular function impairment in pregnancy-induced hypertension.

The changes induced by transient hypertension on cardiac structure and function are unclear. Pregnancy-induced hypertension offers a natural and spontaneous model of this condition. To assess the potential of echocardiographic Doppler to unmask left ventricular function impairment, we studied 28 women aged 26.

Reassessment of electrovectorcardiographic signs of left atrial enlargement.

Echocardiographic left atrial size was correlated with 27 electrovectorcardiographic parameters in 93 subjects. In 20 of them hemodynamic studies, including calculation of the left atrial volume, were performed. Subjects were divided into four groups as follows: Group I, 21 healthy subjects; group II, 45 patients with heart disease but no left atrial enlargement; group III, 15 patients with heart disease and left atrial size from 4.
