[Mechanism of electric alternance in pericardial effusion. Study with ultrasonics].

Two cases are presented, one with chronic renal failure and the other with a hepatic cyst perforated in the pericardium, with a tension pericardic leakage accompanied with by electrocardiographic alternance. After correct treatment, pericardiocentesis and surgery, respectively, the electrocardiogram lost its electric alternance. The echocardiogram evaluates the importance of the pericardic liquid volume which causes, because of the particular cardiac anatomy, an alternating movement of the heart within the pericardic sac. This factor would be decisive in the origen of the electric phenomenon, a fact corroborated when the electric alternance disappears after pericardiocentesis or surgery.

[A simplified method for estimating mitral valve area by Doppler].

Based upon geometrical considerations we have developed a new method for estimation of valve area in patients with mitral stenosis. A special ruler enables us to read the valve area from the Doppler record. We prove that our new method is more precise and rapid than original Hatle's procedure. In 35 patients, we found a good correlation between the result of our method and the valve area obtained by 2D-Echo. Thus the new method is very useful for Doppler evaluation of mitral stenosis patients.

[Color-coded cardiac Doppler].

Color flow mapping with Doppler technique was reviewed. We describe the advantages and technical was reviewed. We describe the advantages and technical limitations of the technique. The usefulness of color flow mapping in acquired and congenital disease was studied. We conclude that new information was added, concerning complex intracardiac flow, in order to the traditional study with classic continuous and pulsed Doppler examination.
