Multiple Local Recurrent Myxoma.

Cardiac myxomas, usually considered benign tumors, occasionally pursue an aggressive clinical course. The recurrence of sporadic myxomas is much less frequent than that of complex or familial myxomas (1-3% vs. 22% vs.

[Two-dimensional color-Doppler in the diagnosis of left ventricle-right atrium shunts].

Left ventricular to right atrial shunts, known as Gerbode's defects, are a kind of uncommon atrioventricular defect, the diagnostic of which had been always based on hemodynamic and angiographic findings. Although, at the present, this diagnosis can be done easily by color Doppler echocardiography, there are few references in the literature. We show 4 patients in whom the diagnosis was made by this technique, pointing out the aspects to keep in mind in order to avoid erroneous interpretations.

[Diagnosis of pulmonary hypertension by means of continuous, pulsed and color Doppler, and its correlation with hemodynamics].

We have performed a study on 28 patients (20 with valve disease and eight with Eisenmenger syndrome) to evaluate the degree of pulmonary hypertension by means of continuous, pulsed and color Doppler, comparing these results with those obtained at cardiac catheterisation. Invasive systolic pulmonary pressure corresponded excellently with the transtricuspid gradient determined by continuous Doppler (r = 0.97).
