          Abstract

          Para conocer mejor la morfopatología de los defectos septales interatriales (DSA) se informa una casuística de necropsia con sistematización topográfica y se propone una correlación anatomoembriológica para entender su patogénesis. Se describieron morfológicamente setenta y un corazones portadores de DSA y veintiséis corazones normales con foramen oval permeable (FOP) de la colección del Instituto Nacional de Cardiología "Ignacio Chávez". Se utilizó el método secuencial segmentario. Se determinó la topografía del tabique interatrial en relación con estructuras vecinas que sirvió de base para clasificar los defectos septales. Se proyectó el área del foramen secundum (FS) sobre la superficie septal derecha a través de alfileres; para establecer la correlación anatomoembriológica se comparó la anatomía del DSA con los procesos embrionarios de la tabicación interatrial. El tipo de defecto septal más frecuente fue la malformación del orificio oval (00) (64.78%), seguido del atrio común (2.81%), FS genuino (2.81%), foramen primum (FP) (2.81%) seno venoso superior (2.81%), seno venoso inferior (2.81%) seno venoso coronario (1.40%). El área del FS se proyectó debajo de la desembocadura de la vena cava superior. El conocimiento morfológico y topográfico de estos DSA es orientador en los estudios de imagen y es de interés para el cirujano y para el cardiólogo intervencionista. Se proponen dos mecanismos patogénicos: apoptosis excesiva ectópica y retardo del crecimiento.

          Translated abstract

          To contribute to a better understanding of the morphopathology of atrial septal defects (ASD), we describe and classify topographically a series of hearts obtained from necropsies. We performed an anatomo-embryological correlation to gain insight on the pathogenesis of this type of congenital heart disease. Seventy-one hearts with ASD and twenty-three normal hearts with patent foramen ovale from the collection at the Instituto Nacional de Cardiología "Ignacio Chávez" were studied morphologically; segmen-tal sequential analysis was used. The topography of the interatrial septum was determined on the basis of the structures related to it in order to classify the ASD. The FS area was projected on the right septal surface using pins. To stablish the anatomo-embryological correlation, the ASD's anatomy was compared with the embryological processes that take place in atrial septation. The most frequent ASD was the 00 type (FS) with 64.78%, followed by common atrium, true FS, FP, superior and inferior sinus venosus, types each one with 2.81% and one coronary sinus venosus type (1.40%). The FS area was projected below the superior vena cava. The morphologically and topographically knowledge of atrial septal defect is useful to interpret the imaging studies of this cardiopathy and is basic for the surgeon and the interventionist cardiologist. Abnormal apoptosis and retarded developmental growth are proposed as pathogenic mechanisms.

            Nomenclature and classification of congenital heart disease.

            At present there is no universally accepted nomenclature for congenital cardiac malformations. Much of the controversy results from failure to distinguish the structural connections of the heart from the morphology and spatial relations of its components. The confusion is compounded by an abundance of individual definitions, many of them speculative. The present article proposes a totally descriptive nomenclature. It describes in turn the connections of the cardiac segments, their morphology, their relations, and additional anomalies in any segment. Each step in the segmental approach is discrete. The overall effect is to force a succinct and comprehensive description of any cardiac malformation, no matter how complex.
