Congenital cardiopathies are the most frequent congenital malformations. Reports of its prevalence around the world range from 2.1 to 12.3 for every 1000 newborns. Prevalence in our country remains unknown, but it probably occupies sixth place for mortality in infants less than a year old, and third place for mortality in those aged between 1 and 4 years.(More)
Surgical development of mitral valve repair techniques in pediatric patients has been slow because of the great variety in the presentation of congenital mitral valve malformations and the still unknown growing effect over the complex mitral valve apparatus. The aim of this study is to review our early an mid-term institutional outcomes in surgical repair(More)
INTRODUCTION Current world tendency is the detection of health problems in order to offer solution alternatives by means of the development of computarized data bases. OBJECTIVE To present the results of a computerized data base developed for the registry of pediatric cardiac surgery with the support of Asociación Mexicana de Especialistas en Cardiopatías(More)
Heart development consists in a group of complex and specific morfogenetic interactions, that requires the proper activity of each factor implicated in this process. Congenital heart defects (CHD) are a group of multifactorial complex diseases with environmental and genetic factors playing important roles. There is not an exact relation between molecular(More)
The diagnosis and treatment for paediatric and congenital cardiac disease has undergone remarkable progress over the last 60 years. Unfortunately, this progress has been largely limited to the developed world. Yet every year approximately 90% of the more than 1,000,000 children who are born with congenital cardiac disease across the world receive either(More)
UNLABELLED Fontan operation is the final palliative stage of patients with univentricular hearts. Cardiopulmonary bypass (CPB) decreases ventricular performance and increases pulmonary artery pressures in the post operative recovery period. It seems that Fontan operation performed without CPB decreases short term morbidity and intra hospitalary length of(More)
The morphopathology of tetralogy of Fallot with pulmonary atresia is detailed as a spectrum of variations which is the foundation to highlight the surgical anatomy of this cardiopathy and it is the embryological basis which determines its structure. Thirty five hearts were studied with the methodology of the segmental sequential system. The atrial situs,(More)
The modified Fontan procedure represents the final stage of reconstructive surgery for most patients with functionally univentricular hearts. Although outcomes following Fontan procedures performed at sea level are widely reported, less has been documented and reported concerning outcomes in regions at high altitude. To clarify the main features involved,(More)
