ABSTRACT
In 30 patients with clinical diagnosis of ischemic heart disease, we correlated the segmental mobility of left ventricular walls as estimated by two-dimensional echocardiography (2-D Echo), and coronary arteriography findings. In consideration to the distribution of the coronary arteries, the left ventricular circle was divided in 5 sections: anterior interventricular septum, anterior wall, lateral wall, posterior wall and posterior interventricular septum. Each one of these walls were divided in three levels: basal, mid and apical, integrating 15 segments. Potentially we could study 450 segments, but it was only possible to examine 444 (98.6%) by 2-D Echo. In 26 patients in whom the coronary arteriography demonstrated ischemic heart disease, the 2-D Echo showed 100% sensitivity and specificity in recognizing the disease. In respect to the number of obstructed vessels, the sensitivity was the same and the specificity 66.6%. Regarding the location of the obstruction; the results of sensitivity and specificity were: for the left anterior descending 96% and 80% respectively, for the left circumflex 87% and 92% and for the right coronary artery 95% and 90%. In regard to the level of obstruction (proximal, mid or distal) the values were 88.6% and 81.8%. Finally, to recognize the presence of significant obstruction (75% or more) the sensitivity of 2-D Echo was 95% and the specificity 76.1%. It is concluded that the 2-D Echo is useful for the diagnosis of coronary artery disease, the number of obstructed vessels, the location, the level and the degree of obstruction.(ABSTRACT TRUNCATED AT 250 WORDS)

We present the case of an 8 year old boy with A-V fistula from the right coronary artery to the right ventricle, successfully treated by surgery. The main clinical features with differential diagnosis are discussed and the advantages of early surgical treatment are commented.

We present here three cases of systemic Lupus Erythematosus which fulfilled the diagnostic criteria of the American Rheumatism Association. These three cases also had Chorea. This kind of association is not frequent and the cases here described are the last three of 32 published until now. We discusse in this paper the significance of the Chorea Syndrome and the probable causes originating it.

1. The first case of Chagasic Miocardiopathy with complete immunologic confirmation is described. 2. The clinical, radiological, and electrocardiographic basis of the case were analyzed. 3. The specificity and the sensibility to the different seroimmunologic reactions in the Chagasic Disease was discussed. 4. An emphasis is placed on the fact that Chagas illness is not a rare entity in the Mexican Republic. 5. We recommend that a campaign of serologic investigation is begin to discover the true frequency of this illness.
