Six hearts specimens of cor triatriatum dextrum, eight with the Chiari's network, and 3 with a membranous remnant of the crista terminalis are studied. These anomalies are interpreted as varying degrees of persistence of the right valve of the sinus venous which reflect different stages of their morphogenesis. The most frequent congenital heart defects(More)
An anatomical embryological and histological study of a malformed heart is presented in which the right concordant atrioventricular connexion is unguarded by the tricuspid valve, due to absence of the three leaflets, chordae tendinae and papillary muscles; only the fibrous ring is present in the atrioventricular junction. This very rare malformation is(More)
The anatomic and embryologic elements forming th crista supraventricularis are reviewed, mainly those absent or dissociated in congenital heart diseases with alterations in the outflow tracts. In order to avoid confusion in the outflow tracts. In order to avoid confusion in the nomenclature of these malformations, we discuss the inconvenience of using(More)
Left juxtaposition of atrial appendages is an anomaly of their origin and position which is associated with a high incidence of complex congenital heart defects. We studied six cases of juxtaposed right atrial appendages. They emerged from the anterior wall adjacent to the atrial septum and were situated to the left of the origin of the great arteries.(More)
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(More)
The goal of this paper has been to count and describe congenital heart disease associated with double conus. We studied 196 pathologic specimens from to the Pathologic Collection of the Department of Embryology of the National Institute of Cardiology "Ignacio Chávez" of México. We found 3% of double conus in classic tricuspid atresia with concordant(More)
INTRODUCTION AND OBJECTIVES The association of univentricular heart with double inlet and Ebstein's "like" anomaly of the common atrioventricular valve is extremely rare. METHODS Two hearts with this association are described with the segmental sequential system which determine the atrial situs, the types of atrioventricular and ventriculoarterial(More)
In order to inform the pathologic features and their associated anomalies twenty five hearts with common trunk were studied with the segmental sequential system. An anatomico-embryological correlation was made to understand the pathological complex of this malformation. The results were: type I truncus (96%), infundibular ventricular septal defect (96%),(More)
The various terms and classifications of ventricular septal defects (VSD) stimulated us to perform the present study with the purpose of adopting a common terminology and classification in which morphologic, topographic and surgical criteria concur. One hundred and one VSD where studied by means of the sequential segmental approach from the pathologic(More)
