The International Committee of Medical Journal Editors (ICMJE) provides recommendations to improve the editorial standards and scientific quality of biomedical journals. These recommendations range from uniform technical requirements to more complex and elusive editorial issues including ethical aspects of the scientific process. Recently, registration of clinical trials, conflicts of interest disclosure, and new criteria for authorship -emphasizing the importance of responsibility and accountability-, have been proposed.

Objective: Cardiopulmonary exercise testing is a tool that helps clinicians to establish diagnosis and calculate risk stratification in adults. However, the utility of this test among children with congenital heart disease has not been fully explored. The goal of this study was to describe reference values for cardiopulmonary performance of healthy children.

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, we present our institutional experience with Fontan operations performed in Mexico city (2,240 m above the sea level), with an emphasis on historical evolution of treatment.

Introduction And Objectives: We report our experience in the surgical correction of anomalous origin of left coronary artery from pulmonary artery (ALCAPA), with an emphasis on the coronary reimplantation technique and its outcome.

Methods: We designed a retrospective, longitudinal, descriptive study that included patients with ALCAPA who underwent surgery involving coronary reimplantation over a 19-year period. We describe perioperative details such as variations in the surgical technique and the postoperative outcome in terms of morbidity and mortality.

The epidemic of childhood obesity, the risk of developing left ventricular hypertrophy, and evidence of the early development of atherosclerosis in children would make the detection of and intervention in childhood hypertension important to reduce long-term health risks; however, supporting data are lacking. Secondary hypertension is more common in preadolescent children, with most cases caused by renal disease. Primary or essential hypertension is more common in adolescents and has multiple risk factors, including obesity and a family history of hypertension.

Objectives: To compare the short- and mid-term outcomes of surgical (SUR) vs. transcatheter closure of secundum atrial septal defect (ASD) using Amplatzer septal occluder (ASO) in adults with a very similar spectrum of the disease; and to identify predictors for the primary end point.

Design: Single-center, concurrent comparative study.

A 1-month-old girl was referred at our Institution with a history of heart failure and cyanosis. We established diagnosis of multiple congenital heart disease with criss-crossed atrioventricular connections but concordant. This type of anomaly has a variety of presentations of high diagnostic complexity.

We present a case of a 9 month old female with a history of cyanosis. The cardiovascular evaluation included angiocardiogram and magnetic resonance. The diagnosis was: origin of the right pulmonary artery from the ascending aorta, stenosis of the left superior pulmonary vein, patent ductus arteriosus and severe pulmonary hypertension.

Objective: To compare the hemodynamic state, the severity and reversibility of pulmonary arterial hypertension (PAH) in patients with Down's syndrome and congenital heart disease (CHD) with respect to those without chromosomal pathologies.

Material And Methods: 30 patients with congenital heart disease and left to right shunt were studied, corroborated by echocardiography; 16 patients had Down's syndrome and CHD and the control group was constituted by 14 patients without chromosomal abnormalities and with CHD. The age was R = 4.

In this report we present the case of a patient with ventricular-arterial discordance in which a QAV was diagnosed by bidimensional echocardiogram with the purpose of expanding the anatomical spectrum of the anomalies associated with d-TGA and to manifest the clinical awareness of the consequence that the QAV has on the evolution of the patients that undergo to anatomic correction.

A case of an 11-months-old girl with vomiting and laryngeal stridor is presented, and in whom a Kommerell diverticulum was demonstrated, which is a rare variant of the incomplete vascular ring. It is well known that the magnetic resonance is the best study to define this malformation. In this patient, it was the cardiac catheterization which allowed to define the structures that constituted the vascular ring.

We present the case of a giant aneurysm and dissection of the abdominal aorta in an eight month old infant. Imaging studies especially a helicoid computerized axial tomography with 3D reconstruction, showed a lesion which extended from the diaphragm to the iliac arteries. The clinical findings and the above mentioned studies revealed non-obstructive heart rhabdomyomas, tubers in the brain and the abdominal aortic aneurysm, all of which were consistent with the diagnosis of tuberous sclerosis.

The purpose of this retrospective study was to determine the outcome of patients who underwent a Fontan procedure at National Heart Institute "Ignacio Chávez", Mexico, from January 1989 to December 2003. We had 81 patients with a mean age of 7 years old: 53 with tricuspid atresia, 14 with pulmonary atresia and intact septum, 11 with univentricular atrioventricular connection and 3 with Ebstein's anomaly. An intra-atrial tunnel was performed on 61 patients and an extracardiac conduit on the rest.
