Introduction: Congenital heart disease (CHD) has an incidence of 8-10 cases per 1000 live births. In Mexico, there are 18,000-20,000 new cases per year. Most tertiary care centers for CHD attend only pediatric population; the Mexican Institute of Social Security (IMSS) has a clinic that attends pediatric and adult population., Objective: To analyze the demographic aspects of the CHD clinic of IMSS., Methods: From 2011 to 2016 a cross-sectional study of the CC clinic of a third level hospital of the IMSS, including all patients with confirmed structural heart disease of recent diagnosis was carried out. The sex, age, reference entity, antecedent of pregnancy and treatment were registered. The population was divided into age ranges (<2 years, 2.1-6 years, 6.1-10 years, 10.1-17 years and >17.1 years). Descriptive statistics and χ 2 test were used in qualitative variables., Results: 3,483 patients with CHD (male:female ratio, 0.8:1.2) were included. Increased pulmonary flow acyanogenic cardiopathies were the most frequent CHD group (47.2%), with atrial septal defect being the most frequent diagnosis overall; 25.6% were adults and 35% of women with a history of pregnancy. Chiapas was Federal entity with greater proportion of patients diagnosed in the adult stage (33.82%); 7% were not candidates for any treatment for complications of the disease., Conclusions: CHD is a late diagnosis; it is necessary to create a national register to promote new health policies and a rational distribution of resources for these patients., (Copyright © 2017 Instituto Nacional de Cardiología Ignacio Chávez.

Unlabelled: Congenital coronary artery fistulas are uncommon anomalies, however themselves may resemble the whole spectrum of cardiac manifestations. Clinical presentations vary considerably from adults to children., Material and Methods: patients with coronary artery fistula diagnosed by selective coronariography in the period from 2000 to 2007 were included., Results: 7 cases were found, 4 children, mean age 6.5 years, and 3 adults, mean age 25.6 years. The fistulae originate from the left coronary artery in 3 children, 2 connect to the pulmonary artery an one to the right atrium, in one child the fistula originated from the right coronary artery and terminated at the right ventricle. In the 3 adult patients, the fistula originated from the right ventricle, two connected to the right ventricle and one to the coronary sinus. Two children were operated on successfully and are asymptomatic 1 and 4 years later. In an adult patient with surgical ligation was performed, 4 weeks later developed an uncomplicated myocardial infarction. We reviewed the literature available and were compared with our cases., Conclusions: The clinical manifestations and hemodynamic features differ in childhood and adulthood. Coronary angiography is the primary diagnostic tool. Surgical treatment has low mortality and morbidity.

Ectopia cordis is an extremely rare cardiac anomaly. The heart is localized partially or totally outside the thorax cavity. This anomaly occurs as an isolated defect or combined with others midline defects. Cantrell and colleagues described, in 1958, a syndrome including defects of the abdominal wall, sternum, diaphragm, pericardium and heart. There are few successful surgical cases with this pentalogy. We describe a case with this Cantrell's pentalogy. The cardiac malformation was a univentricular heart with pulmonary stenosis. The patient underwent successful surgical palliation with a systemic-to-pulmonary anastomosis and uneventful recovering.

The primary cardiac tumors are inusual, the incidence varies in all the ages between 0.005 to 0.05%. In pediatrics patients the incidence is 0.27%. The more frequent tumors during the childhood are the cardiac rhabdomyomas. These tumors are considered benigns. The clinical expression is wide, in the most the cases, the patients are asymptomatic and are detected by murmurs. In the prenatal age are manifested by arrhythmias or hydrops fetalis. The neonates and children may be show cardiac arrhythmias, low cardiac index and sudden cardiac death. The association with tuberous sclerosis had been reported in 81%. We present a neonate with cardiac rhabdomyoma diagnosed in the newborn period when he was asymptomatic, however in the follow-up he developed cardiac failure by obstruction in the out flow tract of the right ventricle. He underwent open cardiac surgery to resect the obstruction. Five months after surgery, the patient remain asymptomatic.
