Arterial oxygen saturation in healthy Mexican full-term newborns at different altitudes above sea level.

Background: Arterial oxygen saturation (SO) values are used to make clinical decisions that might change a patient's prognosis, and it has been proposed as the fifth vital sign. This study aimed to determine the variation of SO at different altitudes above sea level (ASL) in healthy Mexican full-term newborns.

Methods: From July 2018 to June 2019, a cross-over study was conducted in six hospitals at different altitudes ASL in Mexico.

Idiopathic dilatation of the right atrium. Case report and literature review.

Idiopathic dilatation of the right atrium is a rare malformation characterized by disproportionate growth of the right atrium in the absence of a cause that justifies it. We present the case of a patient with idiopathic dilatation of the right atrium diagnosed since fetal life.

Early Bidirectional Glenn Procedure as Initial Surgical Palliation for Functionally Univentricular Heart with Common Arterial Trunk.

We report an unusual case of a 2-month-old baby with a diagnosis of common arterial trunk and double outlet right ventricle with a remote type ventricular septal defect. Taking into consideration the physiologic moment and anatomic findings of the patient, we planned and successfully performed a bidirectional Glenn procedure as its first palliative procedure.

Pediatric multisystem SARS COV2 with versus without cardiac involvement: a multicenter study from Latin America.

Latin America (LATAM) children offer special insight into Severe Acute Respiratory Syndrome Coronavirus 2 (SARS COV2) due to high-risk race/ethnicity, variability in medical resources, diverse socioeconomic background, and numerous involved organ systems. This multinational study of LATAM youth examined the distinguishing features of acute or late multisystem SARS COV2 with versus without cardiac involvement. A consecutive sample of youth 0-18 years old (N = 98;50% male) presenting with multisystem SARS COV2 to 32 centers in 10 Latin American countries participating in a pediatric cardiac multi-imaging society were grouped as with versus without cardiac involvement, defined as abnormal echocardiographic findings or arrhythmia.

[Presentation and management of congenital heart disease in the first year of age].

Congenital heart disease (CHD) is defined as a structural abnormality of the heart or large intrathoracic vessels. They constitute the most frequent congenital malformation at birth. At least one third of patients require some type of intervention before the year of age.

Outcomes of the Non-fenestrated Fontan Procedure at High Altitude.

Background: Although high altitude has been considered a risk factor for the Fontan operation, and an indication for fenestration, there is a paucity of data to support its routine use. Fenestration, with its necessary right to left induced shunt, together with the lower partial pressure of oxygen found with progressive altitude, can significantly decrease hemoglobin oxygen saturation, and therefore, it would be desirable to avoid it.

Objective: To analyze immediate and medium-term results of the non-fenestrated, extracardiac, Fontan procedure at high altitude.

A Novel Private-Public Hybrid Model for Treatment of Congenital Heart Disease in Mexico.

Mortality after surgery for congenital heart disease (CHD) in Mexico is significantly higher than in high-income countries due to structural, medical, and financial factors. In Mexico, public hospitals have a large volume of patients but inadequate quality control systems, whereas private hospitals, although having higher quality control systems, have an insufficient number of patients to build programs of excellence. We describe the creation of a novel hybrid private-public program in Mexico that leverages the advantages of both sectors while establishing an integrated multidisciplinary unit that has allowed us to improve the quality of care for patients with CHD.
