ABSTRACTThe hospital of the Mexican Institute of Social Security (MISS), the National Medical Center La Raza “Dr. Gaudencio Gonzalez Garza” (NMC La Raza), is a center of reference and concentration for medical attention provided in our country, preferably we provide pediatric medical care and a high percentage of those with congenital cardiac pathology.
The incidence in our hospital is according to the results posted in the medical journals, being the most frecuent: Interventricular Communication (IVC), Interatrial Communication (IAC), Patent Ductus Arteriosus (PDA), Coarctation of the Aorta (CoA), tetralogy of Fallot, Total Anomalous Pulmonary Venous Connection (TAPVC), Transposition of the Great Arteries (TGA), among others. The aorto-ventricular tunnel is an infrequent congenital heart disease less than 0.1% of all congenital malformations, of which 90% of the cases communicate the left ventricule. About 130 cases have been reported until 2007, prevailing the male cases in ratio 2:1. Some patients present a heart murmur and cardiomegaly, but most of them suffer from heart failure in the first year, the study of choice for diagnosis is echocardiography. Generaly they are treated with surgery, but in selected cases they can be treated with percutaneous catheterization.
In our hospital this is the second one in 15 years, both male and they were treated with surgery. The diagnosis was initially suspected by echocardiography and through tomography was performed in final form. The information in reference to the anesthetic management for this congenital heart disease is limited, Carol L. Lake et al., described briefly the anethetics objetctives improving the ejection fraction and the afterload; the decrease of the systemic vascular resistance and improving more flow forward, as well as chronic vasodilator therapy, diuretics or digital; the use of halogenated and the previous mesurements to the cardiac cannulation, and to the bypass output.
Due to the insufficient management coupled with the rarity of this malformation, we took on the task of reporting this case providing tools for treatment from the point of view anesthetic.
