Chagas disease as a cause of symptomatic chronic myocardopathy in Mexican children.

We report the first case series of children in Mexico living with symptomatic Chagas disease causing chronic myocardopathy. The findings suggest that children with Chagas disease may develop symptomatic chronic myocardopathy earlier than previously recognized. Our findings emphasize the importance of longitudinal cardiologic follow-up of all children identified with acute Chagas disease.

[Hypoplastic left ventricle syndrome. Report of a case in an adult woman].

Patients with hypoplastic left heart syndrome without surgery dye during the first year of life. In the literature there is only one report from our institution of a patient who survived to the second decade of life without surgery. The purpose of this work is to describe a case of a 24 years old female with hypoplastic left heart syndrome, who has survived until now in functional class I of New York Heart Association without surgery.

[Clinical and echocardiographic characteristics of scimitar syndrome].

Seven patients with scimitar syndrome underwent retrospective clinical and echocardiographic examination. The findings were: respiratory infection with dyspnea on moderate exercise in 90%, scimitar sign in four (57%), dextrocardia in five (71%), and interatrial septal defect in five (71%), one of whom had patent ductus arteriosus. Overall, two patients had patent ductus arteriosus: one also had aortic coarctation and the other, a bicuspid aortic valve.

[Right atrial isomerism in adults. Clinical and echocardiographic study].

The most important feature of right atrial isomerism in the heart is the presence of both atria with morphologically right atrial appendages. The main aim of this study was to do a description of clinical and echocardiographic findings in adult patients with right atrial isomerism. A total of eleven consecutive patients were identified with a diagnosis of right atrial isomerism and complex congenital heart disease.

[Anatomo-echocardiographic correlation of scimitar syndrome in adults].

It is a retrospective study of 7 patients with clinical and echocardiographic assessment, the last was correlated with morphologic features of one equivalent anatomic specimen. The results are: respiratory infections and dyspnea in 90% of cases, scimitar sign in four (57%), interatrial septal defect in five (71%), one of them with patent ductus arteriosus, two (28.6%) only with patent ductus arteriosus.

Anatomic three-dimensional echocardiographic correlation of bicuspid aortic valve.

This study was undertaken to verify the echocardiographic characteristics of bicuspid aortic valve (AV) using 3-dimensional transesophageal echocardiography by comparing the findings with anatomic examination of autopsy specimens from carriers of this condition. Three-dimensional reconstructions of transesophageal echocardiograms were performed on 14 patients with bicuspid AV, and 20 autopsy specimens of bicuspid AVs were analyzed. Echocardiographic images and autopsy material were correlated.
