[Persistent left superior vena cava and rheumatic mitral valve stenosis studied with echocardiography].

A case of persistent left superior vena cava associated with rheumatic mitral stenosis in a 27 year old woman is described. Comments are made of the echocardiographic findings of a space free of echos located at a level behind the back wall of the left ventricle, at a level of the mitral valve. Echocardiographic Mode and two-dimensional technics were used in the observation of this image. Other pathologies, in which is possible to obtain similar images are also discussed, as well as the value of using echocardiographic contrast studies in the differential diagnosis.

Pathologic intrathyroidal parathyroid glands.

BACKGROUND: Parathyroid glands originate from the third and fourth branchial pouches and migrate caudally to their final positions. Aberrations during migration result in anomalous locations. Intrathyroidal location is not common. METHODS: We reviewed cervical explorations performed from 1974 to 1993 in hyperparathyroidism patients. RESULTS: We found pathological intrathyroidal glands in six patients. Three patients had adenomas (left superior, left inferior and right inferior glands). The hyperplastic glands were left inferior in one patient and right inferior in the remaining two. Intraoperative diagnosis was made in three cases in which palpation of the thyroid gland showed a nodule that was suspected to be the parathyroid missing gland. In three patients it was a finding in thyroidectomy or hemithyroidectomy specimens, two of them with associated thyroid nodular disease. CONCLUSIONS: Ipsilateral thyroidotomy on the side of a palpable thyroid mass or blind hemithyroidectomy are justified if a presumably pathological intrathyroidal gland is suspected, when all other sites in the neck have been excluded.

[Echocardiographic evaluation of ischemic cardiopathy].

We studied a group of patients with ischemic heart disease divided into two groups: Group I coronary insufficiency. Group II myocardial infaction. We centered the work on the following aspects: analysis of the contractility; evaluation of the movement of the ventricular wall and of the septum; movement of the mitral valve; diagnosis of ventricular dyskinesias, akinesias, and hypokinesias. The patients in group I did not show significant alterations in the values of the ejection fraction and speed of circunferential shortening. The mean values of these parimeters are significantly less than the group of patients with infarcts, and 41% of these patients have EF less than 50% and Vcf less than 0.9. We did not find a correlation between these perimeters and the localization of the infarct. The velocity of the posterior ventricular wall was disminished in both groups of patients. The amplitude of movement of the posterior wall was reduced in the group of patients with infarctions. These parimeters were more altered in the posterior infarcts than in those with anterior localization and they are more an index of the state of the posterior wall than of the ventricular contractility considered overall, contary to mitral descriptions. In 3 cases of acute infarct we found paradoxical movement of the septum, which normalized itself in one patient in 6 months. In 6 other patients with old infarct we observed localized dyskinesias of the septum and of the free wall of the left ventricle. The mitral valve appears altered in a great proportion of coronary patients the most notorious characteristics being: a decrease in the EF pendent; an increase of the F index. These findings are considered in relation with the ventricular pressures and with the degree of distensibility of the left ventricle.
